Wait, a CPU socket is only rated for 10 insertions and an M.2 connector only for 60?! That's the actual thing I learned from this video. That's kinda shocking tbh.
Funny story about storage removal: in my early computer days I used a laptop with Ubuntu Linux, while not really knowing how to USE Linux. I tried formatting a USB stick, and somehow managed to FORMAT THE BOOT DRIVE. It actually completed the process of erasing itself and ran fine for 10 seconds after. I didn’t realize until I tried to open the usb stick and crashed.
"When in doubt: Blue Screen" is actually really acurate to the mindset of a BSOD/Bugcheck. It basically means that either some Kernel-Mode driver or the kernel itself has no damn clue what the crap is going on, and can't safely continue to function. Hence why Linux sais "Kernel Panic: Not syncing". It's not syncing to the disk because something has gone catastrophically wrong (e.g. you are dereferencing a NULL Pointer in Kernel-Mode) and it would be unsafe to keep going.
I had a situation about a month ago where one of my RAM sticks was dying and the behaviour you described when "yanking" a RAM stick was very similar to what I was experiencing some times. At first I thought it was the MOBO going kaput but thankfully it was just a single stick. In all due honesty, nobody's going around yanking their components but faulty components can sometimes act like they're disconnected so knowing what it looks like when those things happen is quite useful.
In modern PCs, the CPU isn't who commands the system to turn on (at least not when fully off), it's actually a couple of chips on the motherboard that do: the "SuperIO" along with the "chipset". In my experience, removing the OS drive in Windows doesn't blue screen immediately; instead appears to keep running but simply programs and basic OS UI elements begin to not respond; then the unresponsiveness gets worse over time that the computer becomes unusable. Mouse pointer never freezes, no BSoD, simply becomes so unresponsive that becomes unusable.
@@kuhljager2429 now that you mention it, only twice I did experienced a BSoD by bad OS drives, but suprisingly never by disconnected drives (or maybe after a while, not immediately).
@@lucario4483I pulled out the HDD on my latitude E6510 while running windows 7 pro and got a BSOD after a few minutes but I have the page file disabled on all my windows computers, I did it because I wanted to see what would happen and I didn't have anything important on the drive.
Since Windows 8, Windows actually attempts to survive a temporary main drive disconnect. The kernel intentionally hangs practically all processes for a few seconds and sees if the drive comes back online. If the drive comes back, it keeps going as if nothing happened. Only after the drive reconnect window times out do you actually get the BSOD. Presumably, this safeguard was implemented as part of Windows To Go. Windows To Go is a feature of Enterprise versions of Windows that assists users in installing Windows to external, removable storage. It requires fairly beefy, fast USB drives that can tank Windows' space requirements and constant disk activity. As a result of effectively providing official support for installing Windows to external storage, they had to make it reasonably resilient to the boot drive dropping off the bus. Of course, this only works on the internal storage if the system BIOS/UEFI handles SATA/NVMe hotplug. Otherwise Windows is not informed that the drive actually disconnected and instead receives corrupt data, which either crashes or hangs, but the system basically can't recover then. The OS kernels (both Windows and Linux) also support running with less than the total available RAM for debugging purposes. Then, removing a stick of RAM should be safe if it is completely unused by the software and firmware. And whether or not removing the GPU (or any PCIe devices) is safe relies mostly on the hardware and firmware not shitting their pants, and properly reporting to the OS. Assuming the motherboard supports PCIe hotplug, the drivers mostly handle it fine. After all, eGPU drivers come from the same codebase as their PCIe siblings. Linux even supports securely ejecting PCIe hardware the same way it does for USB devices.
@@3lH4ck3rC0mf0r7 I guess that's why I've experienced some resilience in modern Windows: the drive wasn't actually disconnected, but having a faulty SATA cable/connection; or the drive was just really bad (that hangs loading due to physical bad sectors)
Not exactly the same, but related. There’s a technique for reading RAM on a PC that is locked by quickly removing power, powering back up, and then booting into special recovery software. It relies on the RAM not completely losing data for something like a second or two (I forget the actual avg timing). Because of this, there is a chance that you could pull the RAM and very quickly get it into a homebrew device to keep it powered until you get it somewhere safe
Dongles could be used for power connectors. So the end of the dongle is what sees most of the wear. PCIe risers could help also. Then there's the old fashioned way, repair it, but that's just crazy.
It doesn't actually limit you, it's just that the manufacturer (AMD and Intel in this case) have only tested the socket to work for ~10 insertions. It may still work after 100, even 1000, it's just that they never actually cared about making the socket endure this many insertions. At worst, you might not get a warranty replacement if you did it that many times.
I remember the video of Linus doing PCIe hotswapping and the problems it entailed... The only things I know of that really cannot be hotswapped are things like PS/2 keyboards/mice and M.2 drives. PS/2 hotswapping doesn't cause any problems other than the fact that you have to restart the computer. In situations where PCIe, CPUs, RAM and SATA need to be swapped, daughter boards are used and are designed to prevent damage. Even things like power supplies, in servers, can be hot swapped, but you require at least one PSU to be active at all times (which is why redundant PSUs exist).
My experience, mostly with computers that are 20+ years old at this point, is that PS/2 can actually handle being hot swapped and will work just fine after, though this is usually only at the BIOS. It's Windows that can't handle it correctly and requires a restart. On Linux, I've plugged a PS/2 keyboard while it was already booted and it just worked
At 0:45 you say a modern socket is rated for only ten insertions? That stood out to me wildly because I work at a tech shop and have to remove CPUs A LOT. I looked it up and that claim doesn't seem valid. A lot of sites like tomshardware where that "ten insertion limit" isn't even mentioned when talking about swapping CPUs... Could y'all back that up or expand on that? Did Intel/AMD tell y'all? Idk it stuck out like a sore thumb and now I'm super curios where you got that claim.
I actually did some research because i thought there must be limits specified. Finding specific socket info is kinda hard but i found LGA 775 socket specs and there it says ''socket must withstand 20 insert cycles''. So i don' see it unreasonable that some sockets only are made to withstand 10.
It's a "rating" not a limit. It's like how you need to get your oil changed every howeversomany miles/kilometers. You can certainly drive it a lot further than that and continue to use it but the chances of things going wrong increases.
Look at @SmolPotatowo 's reply; with caution with removing CPUs from sockets, the socket can potentially last significantly longer than its rating. The rating only shows how many times it can be inserted before the likelihood of something wrong occuring increases. Matter of fact, the channel replied to another comment saying the exact same thing we are. Notice how the three of us also never specified a number - different mobos will have different socket ratings, but even with the scarce amount of research I did (thank you comment/replies :D), the consensus seems that 10 and 20 are the most common values for a given CPU socket rating. It all depends on the mobo. If anything, just another detail to think about when working with PCs :)
Wouldn't it be great if it were standard for PCs without a CPU to boot to the point where you could update the BIOS / UEFI? This way you could, for example, update it to make the board compatible with the CPU you want to install. Edit: So that even the Brainy Smurfs are getting it.
Well the cpu executes the BIOS to begin with, but perhaps a motherboard with BMC could do it, they're not consumer grade hardware though and I don't think they'd sell enough for the added cost, maybe on those $1000 elite ones
Full boot is asking a bit much with everything a modern board does... but it's absolutely idiotic that anything wouldn't have flashback in this day and age.
Some are but having this kind of features is expensive, since many components (specifically the GPU card) are connected directly to the CPU for best performance. Adding a way to control them while there is no CPU will require redesigning the traces and adding extra switches and might not be a sensible use of both space, performance and money.
As someone who's accidentally restarted the wrong SAN node: Windows Server will keep running even without any IOPS response for extended periods of time and resume operations once the SAN is back up. That said, this is a case of 'system drive unresponsive' rather than 'system drive disappearing'.
It's very fun when your game harddrive fails on you while you're gaming. Your game keeps running for a while, but gets progressively worse with each second. Like i wasn't able to use the menu in the game at all hahaha
There's an exception to this "Pulling out the OS drive will BSOD". Namly, if you system has the Windows To Go flag enabled (or if it's an actual Windows To Go workspace), then pulling the system disk will just freeze. If you reinsert the disk to the same port within 60 seconds, then the system will resume working. Otherwise, it will power off the machine.
It doesn't actually just "freeze". You get a nice warning message that asks you to plug in the USB drive back, and warns you "Your Windows To Go workspace might crash".
MrYeester has has a couple of videos on this. One where he removes a CPU while the PC is running. He also has one where he removes different components while the PC is on
the damage is usually caused by a spark that is created for a short amount of time a high potential difference will be generated to damage FET transistors (which are very sensitive), diodes and possibly capacitors therefore a protective circuit is used in external ports to avoid this spark that can damage those components
I know from experience, removing power to the hard drive on my old Windows 7 computer caused the computer to immediately reboot and boot to a "Boot drive not found" screen. The computer was built in 2013 and is a relic nowadays but it didn't hurt anything once I restored power to the hard drive. And no, I didn't just pull the hard drive out, it was a bad connection that dropped out all of a sudden.
In the 70s, I programmed on a small main frame, the power went off from lighting, the computer used core memory. When the power came back on, the computer continued processing where it left off with no loss of data.
This is the sort of question I expect my non-techie friends to ask me out of sheer boredom. I'd probably tell them what a dumb question it is, but secretly be like "but what happen though? 🤔"
In many server system a lot of component including CPU (in multi socket configuration), RAM, PCIe cards, fans, drives etc are hot swap able so can be safely changed while the system is still running.
Well, I happened to know that the LGA 1155 socket used for Ivy and Sandy Bridge was rated for 20 insertions, and that there was a lot of talk when LGA 775 came out about processors no longer being user-serviceable because they don't use PGA anymore... LGA was touted as a reason why only technicians should be installing or removing CPUs now, and people were up in arms about it. Did future processors become that much more fragile? I wouldn't expect LGA 1150, 1151, or even 1200 to be a lot more fragile... but maybe with 1700 pins, now it is so fragile that it can't be replaced more than 10 times.
I’ve done this before. I pulled my ram stick out while pc was on. Computer froze but remained completely on with out any problems. Shut pc down removed all power and put ram back in. Started up fine. This is why I love micron ram. I was 14 when I did this by the way. I am 36 now :)
I've removed old HDDs, my GPU(by mistake) and a DVD drive while my PC was running, even spilled water in one. But the only thing that's ever killed a component was a single splash of orange juice that hit my GPU on the back and fried it. What I've learned is that as long as it's not orange juice, it won't kill anything. Probably.
one time i was testing a couple different CPUs in a pc, swapping them out-benchmarking then swapping again, I accidently pulled the CPU out before the PC shut off and there was a Loud zzzzZZZZZAP-POP with a nice bright blue lightning bolt between the CPU pins and the socket, right in my hands Didnt check if that CPU worked and sold it for parts, mobo worked fine surprisingly.
I've pulled SATA-DATA from System's (Win10) drive by mistake yesterday, due to poor connection. System wasn't responsive, but was able to start browser and even task scheduler. This data was probably cached in RAM anyway, and a few minutes later completely froze, even tho the cursor was moving. No BSOD appeared. The system was a haswell-based desktop I believe. I'm surprised you've mentioned U.2, but not SAS or IDE.
😂, I have actually done this Many Many years ago just to "Experiment" along with RAM modules, PCI/HDD cables, AGP/PCI cards, SATA cable, bios/CPU jumpers etc. Tried it all just to SEE what happens. 😂

I whip mine out wherever I go. Work, library. When I'm at the coffee shop on my laptop, wait. They can't come out there it's soldiered down but you get the overall idea.
For the people gasping at the low rating numbers. These sockets are fragile. They are RATED at these low numbers because the manufacturer can't guarantee the component beyond this many insertions. It will work just fine if you use the slot more times than this on most occasions, but the metal pins may warp and the connections may become less reliable. Especially on LGA sockets.
When it comes to sudden removal of the GPU the ability for the OS to recover is dependent on the PCI Express controller being able to notify the operating system that a card has been removed. Note it is also particularly dangerous to remove the GPU card on modern computers because the slot designated for the GPU is wired directly to the CPU. The risk depends on how good the protective circuitry around the PCIE lanes is.
Removing the CPU while the system is running, might not neceserally shut the system off. The superIO chip is responsible for power managment in the system and it doesn't react to the CPU suddenly dissapearing, but to a huge voltage spikes that appear on the regulators as such big load suddenly dissapears.
Had sticky thermal paste in my dads prebuilt, never had paste get sticky. I neglected the fact that my pga cpu would be yanked out if I pulled on the cooler. Seemed like nothing happened but I damn near had a heart attack.
5:57 Yes, slim it down by adding built-in ads, subscriptions to the built-in programs, and making the entire OS spyware with an OS as as a crappy afterthought.
Once I was wondering why Cities: Skylines was all of a sudden very slow and really bad at drawing light rays like it had to draw them but didn't have any shaders to customise the rending of them. Turned out the HDMI cable was plugged into the CPU rather than the GPU because the monitor was being hot swapped for laptops back them.
I remember playing Dragon Age 2, off an external drive where the cable had a tendency to... fall off sometimes. When it did so, the game would run perfectly well... UNTIL it needed to load something new (like a new area) and then i got an infinite loading screen... IIRC there where some music glitches too, but cant be sure.
Something similar happened to me when a hard drive started failing while I was playing Skyrim. Right in the middle of a tavern, the game suddenly got super laggy as it had trouble reading data in. Might've been as simple as the tavern bard changing songs, or two NPCs starting a conversation. It was a known failing drive I'd had issues with before, on an old PC I'd already replaced as my main PC -- so not a huge surprise. The only reason I was playing on it at all was that I had Linux on the new PC, and had never gotten Mod Organizer (with its virtual file system for easily loading and unloading my 200+ mods from the game) working properly on Linux.
back in the Pentium 4 days I actually did pull out a CPU while the system was powered on, the PC died immediately, it booted up normally when put the cpu back in.
I was shocked that the CPU is only rated for 10 insertions but then I thought about it and couldn't come up with a single reason why I would ever insert it more than once...
I did accidentally rip a CPU out of a running machine once. It was a P4, some Dell slimline case, I was trying to pull a fan shroud. The shroud was apparently attached to the heatsink and the CPU was attached to that. All it did was turn off. I put it back together, booted it up, and never had a problem.
The craziest thing i ever hotswapped was a bios chip way back in time when it still was a "removable" eeprom on the mainboard.. i use " here because it was not that easy without the pc resetting.. but after a couple of tries i succeeded and could recover my friends corrupted bios flash on his identical mainboard....
I accidentally removed a processor from a laptop while it was on. I had closed the lid earlier in the day but didn't shut it off. I pulled the CPU to clean it and put new paste on it, reinstalled it and flipped open the lid and it was sitting at the windows desktop. And apparently complete unfazed. It didn't lock up or anything. I guess sleep mode powers off the CPU but keeps the ram running. It was a second gen core i7 Dell laptop if that matters to anyone.
I’m glad I don’t have to listen to my inner child and try this myself anymore 😂 👍 For the next video though, please use some background “noise” that doesn’t sound like a phone is ringing all the time (and No, ofc I did not start looking for the ringing phone in my room while watching this video😅)
Ive pulled the CPU like this before. Computer was off but plugged in. I was in the habit of leaving the power plugged in from when PCs had actual power switches (to ground the case), so the PC was still technically on; waiting for a signal to power on everything. The system crashed and would not power on until i unplugged it.
Once, a colleague hot unplugged a SATA hard drive from a Windows 8.1 computer (he was tinkering and mixed up which case under the desk was which) and Windows just froze like when you wait for a hard disk to wake up from standby, but surprisingly did *not* crash. When he plugged it back in, Windows just kept on going as if nothing had happened!
The gpu response reminds me of the time my 2090ti from a prebuild that happened to have ass warrenty compared to the rest of the industry decided to shit itself. Constant bluescreens, recovery modes, etc. I now have a 3070 directly from nvidia, with 5 years of warrenty instead of just 1.
Regarding Linux without it's HDD, had a situation in the company i work for (Networking company) a while ago, where one of our webservers HDDs completely failed (the entire RAID if i remember correctly). I remember a colleague writing into our chat "Okay, nobody reboots the Webserver1 now, the HDDs failed and it is solely running of RAM right now!". I didn't know it was possible before, but was a rather cool moment to learn that.
I heard a story of a person falling headfirst into a open PC and they took out CPU at same time...they now have a permanent CPU scar on their forehead 😢
Wait, a CPU socket is only rated for 10 insertions and an M.2 connector only for 60?! That's the actual thing I learned from this video. That's kinda shocking tbh.
Thats also new for me. Never even thought about that to be honest
No way that is true
Same, now I'm wondering if there's a reason they need to be so fragile, would be another interesting video
I need to see citations. Big wtf moment here.
PCIe and other power connectors are also limited.
USB: "Plug me in 10,000 times".

the damage is usually caused by a spark that is created for a short amount of time a high potential difference will be generated to damage FET transistors (which are very sensitive), diodes and possibly capacitors therefore a protective circuit is used in external ports to avoid this spark that can damage those components
I know from experience, removing power to the hard drive on my old Windows 7 computer caused the computer to immediately reboot and boot to a "Boot drive not found" screen. The computer was built in 2013 and is a relic nowadays but it didn't hurt anything once I restored power to the hard drive. And no, I didn't just pull the hard drive out, it was a bad connection that dropped out all of a sudden.
This video crashed my smart tv. I thought it was a gag till it went on for too long
In the 70s, I programmed on a small main frame, the power went off from lighting, the computer used core memory. When the power came back on, the computer continued processing where it left off with no loss of data.
10 insertions ? So my socket is a legend ? 😂
Im going save your time: Your pc just shut off
I'd like an LTT video demonstrating this in action
In Linus Tech Tips channel they had a video where Linus yanked a CPU out of working PC. The GPU just proceeded to display the last frame in its buffer
Techquickie is officially out of sane topics to cover 😂
Lol
What if you cut your computer in half while it's on?
@@50-50_Grind speedrun strats
next : what happens if you pee on your mobo.
The windows + ctrl + shift + b seems like an excellent key combo to troll streamers with.
This is the sort of question I expect my non-techie friends to ask me out of sheer boredom.
I'd probably tell them what a dumb question it is, but secretly be like "but what happen though? 🤔"
0:43 Only 10 insertions? So does that mean you can only install a CPU 10 times?
yes it does
Yes and no, it means warranty won't protect past 10 insertions but odds are it will be able to handle more
@@FlashDrive356 how they gonna know how many times I inserted 😂
In many server system a lot of component including CPU (in multi socket configuration), RAM, PCIe cards, fans, drives etc are hot swap able so can be safely changed while the system is still running.
Well, I happened to know that the LGA 1155 socket used for Ivy and Sandy Bridge was rated for 20 insertions, and that there was a lot of talk when LGA 775 came out about processors no longer being user-serviceable because they don't use PGA anymore... LGA was touted as a reason why only technicians should be installing or removing CPUs now, and people were up in arms about it. Did future processors become that much more fragile? I wouldn't expect LGA 1150, 1151, or even 1200 to be a lot more fragile... but maybe with 1700 pins, now it is so fragile that it can't be replaced more than 10 times.
Today I learned about the Win + Ctrl + Shift + B shortcut. Neat!
Is Riley starting a new Computer Fetishes series ?
Maybe what happened if you cut down one of the CPU Pin ?
Com'on they have like more than 1K pins
The CPU will work perfectly fine because CPUs usually have duplicate pins
I’ve done this before. I pulled my ram stick out while pc was on. Computer froze but remained completely on with out any problems. Shut pc down removed all power and put ram back in. Started up fine. This is why I love micron ram. I was 14 when I did this by the way. I am 36 now :)
This should be called "What happens if you perform a lobotomy on your PC?"
I've removed old HDDs, my GPU(by mistake) and a DVD drive while my PC was running, even spilled water in one. But the only thing that's ever killed a component was a single splash of orange juice that hit my GPU on the back and fried it.
What I've learned is that as long as it's not orange juice, it won't kill anything. Probably.
I thought my GPU crashed for a bit @ 2:34
This like removing a game from a Gameboy while playing a from it at the same time, but on a whole other level 😂
new for me was the limited duty cycles of any slots of the mainboards
one time i was testing a couple different CPUs in a pc, swapping them out-benchmarking then swapping again, I accidently pulled the CPU out before the PC shut off and there was a Loud zzzzZZZZZAP-POP with a nice bright blue lightning bolt between the CPU pins and the socket, right in my hands
Didnt check if that CPU worked and sold it for parts, mobo worked fine surprisingly.
It'd be cool to see a video about the potential of FPGAs for hardware acceleration
I've pulled SATA-DATA from System's (Win10) drive by mistake yesterday, due to poor connection. System wasn't responsive, but was able to start browser and even task scheduler. This data was probably cached in RAM anyway, and a few minutes later completely froze, even tho the cursor was moving. No BSOD appeared.
The system was a haswell-based desktop I believe.
I'm surprised you've mentioned U.2, but not SAS or IDE.
😂, I have actually done this Many Many years ago just to "Experiment" along with RAM modules, PCI/HDD cables, AGP/PCI cards, SATA cable, bios/CPU jumpers etc. Tried it all just to SEE what happens. 😂
the number of people who tried the win + ctrl + shift + B shortcut after pausing the video on the exact frame has to be staggering
the mere idea of taking anything out while pc is running is just terrifying
Your computer actively protests if you start tearing chunks of its brain out? Shocking.
"Daisy, Daisy, give me your answer do. I'm half crazy all for the love of you. It won't be a stylish marriage, I can't afford a carriage. But you'll look sweet upon the seat of a bicycle built for two."
Now I'm trying to remember the number of times I inserted CPUs in my motherboard.
I whip mine out wherever I go. Work, library. When I'm at the coffee shop on my laptop, wait. They can't come out there it's soldiered down but you get the overall idea.
Filthy Frank!?! My software just became hardware.
We need a full LTT video with Dennis or someone pulling a bunch of components while they’re on.
it was like asking what if..organs were removed while the person is alive and not on anesthetics.
What happens when "madman" Muntz sees a computer for the first time
Evidence suggests the size of the CPU can impact the total number of insertions it can experience.
You didn't explain what happens when you yank the power supply out
For the people gasping at the low rating numbers.
These sockets are fragile. They are RATED at these low numbers because the manufacturer can't guarantee the component beyond this many insertions. It will work just fine if you use the slot more times than this on most occasions, but the metal pins may warp and the connections may become less reliable. Especially on LGA sockets.
Outside of the graphics card, I've never even thought taking out components while it was on.
I had a hard drive fail while the system was working and the system just froze. I think it depends on the age and era of the hardware and windows
When it comes to sudden removal of the GPU the ability for the OS to recover is dependent on the PCI Express controller being able to notify the operating system that a card has been removed.
Note it is also particularly dangerous to remove the GPU card on modern computers because the slot designated for the GPU is wired directly to the CPU. The risk depends on how good the protective circuitry around the PCIE lanes is.
"Keyboard not found, press F1 to continue..." 🤣
"When in doubt, bluescreen"
This seems to have been the foundation windows was built upon.
Removing the CPU while the system is running, might not neceserally shut the system off.
The superIO chip is responsible for power managment in the system and it doesn't react to the CPU suddenly dissapearing, but to a huge voltage spikes that appear on the regulators as such big load suddenly dissapears.
Linus letting intrusive thoughts win.
THAT'S new, when Riley said "Subscribe and follow", the subscribe button went all flashy RGB highlighted. Never seen that before.
I had no idea parts are only rated for a certain number of insertions
Had sticky thermal paste in my dads prebuilt, never had paste get sticky. I neglected the fact that my pga cpu would be yanked out if I pulled on the cooler. Seemed like nothing happened but I damn near had a heart attack.
5:57
Yes, slim it down by adding built-in ads, subscriptions to the built-in programs, and making the entire OS spyware with an OS as as a crappy afterthought.
Once I was wondering why Cities: Skylines was all of a sudden very slow and really bad at drawing light rays like it had to draw them but didn't have any shaders to customise the rending of them. Turned out the HDMI cable was plugged into the CPU rather than the GPU because the monitor was being hot swapped for laptops back them.
If you're running a LiveCD, you can pull the USB drive out, no problem.
I would think that the CPU could burn your hand if you would pull it during a stresstest.
I remember playing Dragon Age 2, off an external drive where the cable had a tendency to... fall off sometimes.
When it did so, the game would run perfectly well... UNTIL it needed to load something new (like a new area) and then i got an infinite loading screen...
IIRC there where some music glitches too, but cant be sure.
Something similar happened to me when a hard drive started failing while I was playing Skyrim. Right in the middle of a tavern, the game suddenly got super laggy as it had trouble reading data in. Might've been as simple as the tavern bard changing songs, or two NPCs starting a conversation.
It was a known failing drive I'd had issues with before, on an old PC I'd already replaced as my main PC -- so not a huge surprise. The only reason I was playing on it at all was that I had Linux on the new PC, and had never gotten Mod Organizer (with its virtual file system for easily loading and unloading my 200+ mods from the game) working properly on Linux.
I'm not convinced everyone would notice if their brain was removed.
back in the Pentium 4 days I actually did pull out a CPU while the system was powered on, the PC died immediately, it booted up normally when put the cpu back in.
I was shocked that the CPU is only rated for 10 insertions but then I thought about it and couldn't come up with a single reason why I would ever insert it more than once...
I do remove power cable from gpu while running because amd gpu have bug which freeze gpu when running under kvm so removing power is only option
I remember pulling out the HDD on my laptop once when I was a teenager while it was running. You're correct; it's a BSOD. :)
I did accidentally rip a CPU out of a running machine once. It was a P4, some Dell slimline case, I was trying to pull a fan shroud. The shroud was apparently attached to the heatsink and the CPU was attached to that. All it did was turn off. I put it back together, booted it up, and never had a problem.
Wow .. only 10 insertions over its whole lifetime? That's rough.
The craziest thing i ever hotswapped was a bios chip way back in time when it still was a "removable" eeprom on the mainboard.. i use " here because it was not that easy without the pc resetting.. but after a couple of tries i succeeded and could recover my friends corrupted bios flash on his identical mainboard....
The term you didn't use but is the correct term for what you're talking about: "hot swapping"
frank has been gone for so long, yet he is still here
LOL "When in doubt Blue Screen" hahahha
Bro brought out Filthy Frank
I accidentally removed a processor from a laptop while it was on. I had closed the lid earlier in the day but didn't shut it off. I pulled the CPU to clean it and put new paste on it, reinstalled it and flipped open the lid and it was sitting at the windows desktop.
And apparently complete unfazed. It didn't lock up or anything. I guess sleep mode powers off the CPU but keeps the ram running. It was a second gen core i7 Dell laptop if that matters to anyone.
I’m glad I don’t have to listen to my inner child and try this myself anymore 😂 👍 For the next video though, please use some background “noise” that doesn’t sound like a phone is ringing all the time (and No, ofc I did not start looking for the ringing phone in my room while watching this video😅)
Ive pulled the CPU like this before. Computer was off but plugged in. I was in the habit of leaving the power plugged in from when PCs had actual power switches (to ground the case), so the PC was still technically on; waiting for a signal to power on everything.
The system crashed and would not power on until i unplugged it.
Once, a colleague hot unplugged a SATA hard drive from a Windows 8.1 computer (he was tinkering and mixed up which case under the desk was which) and Windows just froze like when you wait for a hard disk to wake up from standby, but surprisingly did *not* crash. When he plugged it back in, Windows just kept on going as if nothing had happened!
So, in summary, it causes electrical damage if you take the CPU off.
I was hoping to see PC parts getting removed from a running PC. :(
Linux is "very popular" for servers in the same way that water is very popular for humans and plants 😂
I am a human being and I like water
I really like your videos as I’m not too good with tech things but recently got into learning about them and you explain it very clearly.
Giving me ideas I’ll never test!
The gpu response reminds me of the time my 2090ti from a prebuild that happened to have ass warrenty compared to the rest of the industry decided to shit itself. Constant bluescreens, recovery modes, etc.
I now have a 3070 directly from nvidia, with 5 years of warrenty instead of just 1.
Regarding Linux without it's HDD, had a situation in the company i work for (Networking company) a while ago, where one of our webservers HDDs completely failed (the entire RAID if i remember correctly). I remember a colleague writing into our chat "Okay, nobody reboots the Webserver1 now, the HDDs failed and it is solely running of RAM right now!". I didn't know it was possible before, but was a rather cool moment to learn that.
I heard a story of a person falling headfirst into a open PC and they took out CPU at same time...they now have a permanent CPU scar on their forehead 😢
i will remember "delete me" just in case i had a cancer
