In this video we go over gaming motherboard Z97-G45 and while diagnostic we see that our chipset is "punctured" on two powers to it.
It felt like I was at a medical appointment. The expertise is insane, this guy is the computer doctor.
Would be nice if you could give sort of a checklist what to check when diagnosing a motherboard and what the approximate voltages/Ohms should be otherwise, Great Vid! big thumbs up from South Africa
You should place the camera overhead, so we can see what your'e actually probing... Its very hard to see what your're actually doing, for the 1st half of the video. Thanks for the videos anyway.. Keep up the great work!!!
I agree, please show us what you are actually metering, this way we can't see it.
I do agree with you but I have something to add.

Sit through a few of his streams and you will quickly understand the basic topology of mosfet power circuitry.
Another great topic to research is Buck Converter topology as this is essentially how your motherboard steps down the 12v to 1v and other voltages.
If you watch Eli Tech he is going from ground to the gate or collector of the mosfet to confirm that the entire power rail is down.
Since there is a short to ground overcurrent protection will kick in not allowing the board to turn on.
We probe in peace!

When he says "Hub" he's referring to the PCH (Platform Controller Hub), older computers used a North Bridge and a South Bridge for Intel based chips. AMD had its own PCH called Fusion Controller Hub. Now Intel and AMD simply refer to it/them as the "Chipset", meaningless trivia but here we are.
thanks was lost being a intel guy for life was confused kept talking to the screen calling it a south bridge which I know now is wrong .
Didn’t know this, however to me, that clearly looked like the chipset. I’ve been calling it chipset for some time, but I do remember the north and south bridge, even older AMD boards had this because I’ve owned amd my whole life and I remember upgrading heat sinks on the n/s bridges. Though eventually I noticed newer mobos just had one bridge and they resorted to call it “chipset”
I seem to remember most chipsets back in the day after IO moved from a VESA slot of the '486s to the mainboard when pentiums 1st came out, both AMD and intel had a north and south bridge, later on around the time of the via KT133 chipsets AMD had a lot of extra speed with the magic pixie dust of the inter-chipset communication in the form of a dedicated ' hypertransport' bus, but intel was stuck at FSB speeds between the 2 chips , the oddball of the bunch was the SIS630/730 which was a single chipset that had everything in it, and for once it was a SIS chipset that didnt give a lot of headaches... and performed well enough for the time
@@DevilbyMoonlight Yeah, I remember that too.

thanks
Wow. Troubleshooting a motherboard down to the component level is truly genius.
As an electrical engineer, I really like your videos. Wish you would better show the diagnostic steps though
I could watch you repair electronics all day.
jump the power supply = touch green wire to ground and turns on.
@Robbi Robson i only do to turn on psu if i dont have a motherboard to see if it works.
Nice work! Came here for a DIY solution of troubleshooting but stayed for the entertainment
I'm impressed! If I ever need any repairs of this nature, I'll send it to you. Great work!
You found those power lines like a champ, I usually spend a couple of hours looking for the schematics I bought of some russian forum for 10 bucks!
Where do you buy them? I would like to get a schematic for Rx 480 gpu
@@DragonAndrija it's real rough, because I searched for a while on a bunch of different forums, it would be much safer to buy a parts board instead
This comments funny because it’s true 😂
@@DragonAndrija badcaps
Thanks. That was actually potentially helpful. It's unbelievably hard to figure out the minutiae of not only everything that can go wrong with a motherboard, but what did, which is often first assessed by figuring out what didn't.
mate this is the best video ever, I have work on smd soldering for a year know, it's really satisfying how easy you cleanup the pads
Oh gosh, this is getting much better, now fixing mobos at the component level now
Nice video and hope to see more in the future.
Quick FYI:
Some desktop MOBOs can have a resistance of less than 50ohm on the 5v line (with nothing connected or inserted).
I have 2 Intel boards that show 52ohm and 24ohm on them and work fine. Th is can fool some people used to healthy rails showing 500+ on them.
My first desktop board repair had this. I spent 2 days searching for the 24ohm short on the +5v rail. Two days of prodding and marking data because, surely, 24ohm is a short. Always.
Nope. Got fed up just before taking the PCH off and tested it. Booted right up, lmao. Noticed more like it after that.
If it's showing 20+ ohm and it isn't taking too much current on power injection, it just may be good. Now, here the PCH was getting hot on standby. That's obviously a definite short so look for that but of it stays cool even with powerinjection, test it *FULLY*
(CPU, one stick of RAM, all fans plugged in, etc).
I love your work. I've learned a lot just watching you.
Whenever I use a multimeter, I just blow fuses lol.
If I attempted to use solder on a small chip, the whole board would get it!
Impressive electronic knowledge.
Old video - but a question - What is that card you plug into motherboard? Thank you for sharing your knowledge.
I'm proud your experienced to troubleshoots a dead motherboard. That's the most underrated and comprehensive boardview of that moboard component part operations video tutorial ever so far. But I need help a quick question my friend about my Asus P4P800-E Deluxe motherboard. This is my first time trying to resurrect/repair my dead motherboard. Only certain part I repaired and changed/replaced already the (1) BIOS chip, (2) capacitors, (1) IC-driver controller to mosfet, and (2) transistor mosfets (negative side body) near side of the CPU processor. I have the PTi9 LCD PCI Diagnostic Analyzer Tester...indicates LED lights of +12V, +5V, +3.3V, and Reset are good (lights on) & fan runs means no problem on transistor Mosfets anymore as I double tested too that 12Volts are running good designed to run CPU processor. But the PTi9 LCD PCI Diagnostic Analyzer tester still telling me that there's signal error, it says check the CPU and power box (power supply is tested good all +12V, -12V, +5V & +3.3V) and the other two indicates that RST and FRAME are both Invalid shows in PTi9 tester. Also I'm seeing LED lights of FRAME, IRDY, and SYSClk are off, it shows in the PTi9 PCI Diagnostic Analyzer tester. I have the "Boardviewer" software (to see the schematic diagram of P4P800-E Deluxe board) that I clicked the CPU drawing part and looked at the RESET, looked at the motherboard then tested the Resistor that is soldered/connected on negative side that the value is correct that has no problem. The two pin reset (for the button reset) doesn't work when I pressed the button. If you have time, please try to look on the Boardview in part of the RESET pin because it's not working. I don't know about that FRAME & RST where to troubleshoot that. I touched the CPU processor it doesn't make any at least build up heat/warm. I tested the CPU processor from my other Asus motherboard, it's running fine. What part of the motherboard should I trouble shoot on that P4P800-E Deluxe? This part I'm lost already. I need help, any idea? Great help would be appreciated so much.
Here's what I did, I plugged one 1GB stick ram, 3V battery button, fan for CPU, plugged-in the PTi9 Post Diagnostic Analyzer Tester, unplugged CPU processor and 12V-4-pins, then plugged the 20-pin power supply, then turn it on, everything runs even though it's unplugged CPU and 12Volts-4-pin. On the tester it shows LED lights on at the +12Volts, +5Volts, 3.3Volts, RST, CLK, except FRAME, IRDY, and SYSClk. So, it means the issue is at the Power Block of CPU because CPU doesn't build up warm/heat. Problem is still don't know where is the one that doesn't provide either the +5Volts or 3Volts or 1.2Volts. Intel 82865PE MCH Chipset build up its own heat but it has its own original heatsink since P4P800-E Deluxe was built in & sold in the market.
Awesome thank you, I'm a PC tech from Bolivia, never knew you could buy a Hub Chipset and re-ball it, and checking the voltages was great, we don't have anything like this over here
The probe in left hand while measuring resistance, where are you connecting it? Looks to be outside of the card?
I wish you would have shown the points where you were checking for each item. Thanks for the video.
wow I could just watch this guy all day
Great video. I have a msi motherboard that the cup fan spins but the motherboard shows no display also the pic e slot has no power. What would be your opinion on what's wrong with it. Thanks
Hey i repaired similiar board.Asus Z97 Pro with only 1 bent pin :D
Easy repair
greetings from Indonesia, thank you sir, the knowledge is very useful.
I wonder what type of thermal compound was on the chipset. If it was factory thermal glue/epoxy or if someone replaced it with thermal paste.
I mistakenly took the chipset heatsink off of my main PC (AM2+ socket...) while cleaning it out one day. Thinking it was just thermal paste underneath. Boy was I wrong and what a pain that turned out to be. 5 days of research and 3-4 days of finally scraping that pink crap off with toothpicks I cut in half at an angle - because isopropyl alcohol was ineffective... Luckily I had some thermal pads on hand that I had bought for my old laptop I'm trying to fix up (from the same era). Put 2 and 2 together realizing it wasn't thermal paste initially and there could be some clearance between the die and the heatsink - and it had foam padding, similar to my laptop GPU. Which required thermal padding. - Replaced the pink adhesive with a thermal pad and my chipset temps dropped from around 89°C down to like 56°C lol.
Apparently they're made to withstand high temps, but it's nice to know this old motherboard I had recently maxed out the CPU on might last me many more years. And will be much easier to maintain in the future with thermal padding there.
Hi i have the same bga rework station but sometimes i have problems with motherboards of laptops , motherboards layers blow, what temperature you use?
You are Tech Rockstar. I have to keep rewatching everything. Ogromnoe sposibo.
Where did you buy your diagnostic card sir. And what model is your diagnostic card. Thank you in advance
@Eli Tech, i have asus rog rampage vi apex mobo and few pins in socket are bent and tried unbending them and it worked fine, later on i had a leak in waterloop and A1 memory slot stopped working and i sent it in repair to asus but they declined to repair under warranty due to socket pin damage even though even though it was not a problem, later i tried to mess with pins again and broke one ( like 6-7 pins were bent and i broke one trying to bend them back again, so i purchased a new 2066 socket and i should get it soon, will u be able to replace socket and also check why A1 ram slot does not work, at this point i dont know what else is not working as i have not used it ( but after the leak i dried it good and it booted fine except for A1 ram slot not detecting any ram), do u have time to fix my mobo, thank you.
Hi. You sound like you know a bit about a PCs. I have a Motherboard with no Manual for it and it's not available on line. My header has 10 Pins unmarked. Can you please tell us how to identify Front panel Pins using Multimeter or any other technic without damaging the board. Thank you.
Is it worth doing the reflow of the chipset if the board was bent and the issue could be that the soder balls just got cracked?
I like him when say "we have a picture"
I have a faulty Asus Z270-P Motherboard. It was ultrasonic cleaned but the CMOS battery was left in. After this it doesn't work anymore. Would this be an easy fix or not?
Seems to be that the power supply does not get triggered to power on. I initially thought it was a faulty PSU but i tried another motherboard and PSU worked fine.
Can you tell us what diagnostic/debug board do you use?
Hi, I have a z390 Designare, I had it for 1 year and a half, then I switched my RAM modules, in this specific motherboard I wasn't able to enable XMP, it simply wouldn't post, and when it post, it BSOD or freeze...
It got worse recently, when turning it on it get stuck on DRAM and sometimes VGA (both are fine), then I found out that CPU VAXG is showing 0.0v, reseting the bios didn't changed it.
CPU socket pins seem fine, so I wonder where the problem is exactly...
Could you point out elements to check? I'm thinking this could be a similar problem...
HI! What training do you have or how did you learn?
I have a motherboard that is broken apparently. CPU fans starts spinning and all just shuts off in 2 seconds max. I'd like to learn to diagnose and repair them myself.
I have bootloop mainboard, is it also the symptom of shorted chipset? Or just shorted caps or something?
Hi, so desperate as of now. Have you encountered this problem?
I have a Msi b350m bazooka and a ryzen 5 2400g. Its been almost 2 years, and last friday it wont turn on. I pull out the motherboard from the case, tested it with out the CPU plug in or seated in. The motherboard turns on, but when seated. Motherboard wont even light up. What could be the problem?
Maybe the bios was resetd and the board wont identify the cpu?
do you know if any motherboard at least powers up and throws any lights or codes with ONLY a PSU and nothing else?
asking for testing purposes
I had no 0V on the 1st button(assuming that was the power switch?).
How would I proceed with a repair?
thanks!! but how can know how much ohms should be in there for example how can you know if the normal resistance should be 1k ohms instead of 2k or whatever ?
i hope you'll answer me as soon as possible !
I like when you say "We have a picture" :)
What is the model (and brand) of the tester board wich u put in the PCI slot? Thank You!
hi, I still don't understand why did you change the southbridge if the transistors were not getting power? I believed that the problem was with them not the SB. please explain
im wondering if soldering the hub with a hairgun would do the same trick
Hey man sorry to bother u 2 years after u posted the video, but i have the same motherboard, something strange happened today, i started my PC and i got an instant smell of burning, i turned off the PC immediately, then i opened the PC to see the damage to the Motherboard, to my surprise it was only that small chip that is between those 2 small capacitors beside the sysfan3, so i removed everything from the PC but the CPU + memory, then i restarted the PC and it worked just fine, then put everything back GPU and all, and the PC worked just fine, i could run heavy apps and games no problem, then i used a multimeter to check the voltages on those sysfan3 pins, all was fine, then i turned off the pc and left if to drain all their power, no battery or power for a few hours while i was at work, when i came back i checked the resistance on those sysfan3 pins, all was fine too, so i connected another fan to that sysfan3 and it worked just fine, pwm and all, fan speed worked no problem, the PC works fine but that specific chip between those 2 capacitor close to the sysfan3 its visually destroyed, i can even see the inside of the chip, anyway now im curious about that chip because in my mind it should be impossible for that chip to still be working after literally caching fire and sending sparks... if u want some photos just send me your email or WhatsApp or whatever way u prefer, i am no bot or scammer, i will not bother u i give u my word, if u can spare some time to give me ideias about what that chip does or why the PC "works fine" i would really appreciate.
I have gigabyte Z97 gaming 5 ... it posts sometimes and sometimes it gets stuck during the POST. I wonder how to repair it?
I don't understand . He tested for 3.3 on the main 3.3 pin but surely if the supply is good, then it should show regular voltage?
I would love the video more if the camera was ABOVE view point. Hard to tell what you were testing and why. Why prob 1 point when we have no idea why and what you were probing. Other than that. How much is the charge for the fix.?
why did you replaced the chip. why no reball it first? how did you know what to do?
Hi quick question I have this same Mobo almost, z87-gd65, uses same parts and all, @6:00 of this video that chip you say it has to be over 1k, is that accurate? I have the same problem as this mobo no power and such and by jumping the 24pin like the previous owner did on your mobo I also don't get post or video to recognize the HDMI, well my question really was because both those chips are reading resistance of Left Chip: Left 716 Mid 124 Right 063 and Right Chip Reads: Left 716 Mid 124 Right 063.... Do I also have a short there? I am continuing to check this video to check the board more but that is so far puzzling me.
Hi Eli, do you have a reference for that POST diagnostics board you use? I assume it is always the same - or do you have more that are specific to brand? I would like to repair an old Intel motherboard that doesn't post also.
What diagnostic card are you using for PCI-E?
I can't understand what he said that first card is he plugged in. Did he say plus card? If so what is that?
what are you putting your multimeter probe on near the io port? Looks like the usb header?
sir, my unit is not powerring on if both 24pin psu cable and 4pun cpu cable is plugged in to motherboard. once 4pin cable is removed and 24pin is left connected that is the only time i get the fans running but still no boot.
Hello, do you reprogram the BIOS the Intel ME? i notice when i replace Chipsets i need to reprograme intel ME firmware
Hi, do you know what the part number is for the PCH/hub? I have the same motherboard with the same problem and can't seem to find the PCH chip online.
Hi, I have an old motherboard and I desoldered the speaker buzzer, now it won't power on, no fans, no signs of life, could it be that the buzzer is connected with power pins, and the motherboard won't power on without it?
In which country you live as I got few motherboards that shoud need fix it
What are you probing at 4:45? it's off camera. thanks
Hey Eli,
I got a MSI X470 Gaming Plus, as my brother buyed a PC from ebay where the vendor had no screw in mainboard to fix it.
So while beeing shipped, it inspected every corner of the case. Then, while not booting up, he got a refund and I have now the old board.
It runs again "yeahh", but 2nd memory controller won´t recognize. So it boots up with RAM post beep, recognizes 32GB but only give me 16 to use.
CPU is ok, RAM is ok - so it is the board. Where would you start to search? Measuring from CPU to RAM slot? (Do you have a wiring diagram?)
Br Sascha
so cool man and you are growing as hell I wish my channel grow that fast congratulations my friend
Hi Eli, i have "fix" a msi gtx 970 gaming 4g by removing 1 faulty mosfet and 1 driver, so my card have 4 phases on the original 6 phases, did you think it's can damage it ? (i can not replace the dead mosfet because it was solder to the pcd due to a very hard burn and some trace are gone) Thanks !!
Can you help? I have a keyboard (musical), and I plugged in the wrong adapter (took 9v, I must have used something higher) and I believe it fried something (it doesn't work now). I love that keyboard, I've had it since 1989. Could you offer any ideas/suggestions as to what the problem might be and how to fix it? Thank you :)
Can I ask about my case? The RAM slot 2 and 3 can't detect the ram. The model of my motherboard was Gigabyte B150M-D2H. Can you help me to fix my problem? I need to function it the reason is for multitasking. I really need you help. :(
I have the same board all pcie slots are dead. I also have an evga 1070 system can't find. Can you fix them for me?
would you like to diagnose twin asus z97-a mobo's? they both seem dead in exact same way. when power switch is applied the fan spins up then turns off... repeatedly. never posts.
That reballing machine is one nice thing to have .
What diagnostic card and from where you have purchased it ?
hey bro i was just thinking the customer that had this board that i need to fix, they had the psu floppy cable plugged into a fan header do u know what may have shorted out or burnt out so i can replace it? any ideas thank you its a Asus M5A99FX R2.0
What type or model of fluke are you using?
thank you for all your labor, im getting enjoy and learn step by step. choov
Hi Eli!I have one rly strange problem,i owned a asus maximus V mbo and that mbo works only with a duall core cpu-s!!I change like 2 or 3 cpu-s and work just fine,but when i put i3,i5 or i7 mbo working but shows error 55-memory problem..I try all what i know,from bios,like 20 different memory stick but nothing..So i dont know if u ever have simular problem i bee glad to give me some edvice what to doo..
Greatings from Croatia
Eli Tech, can you tell how to fix SATA3 ports , or what to look for when trying to diagnose it?
Astonished! This kind of knowledge is mind-blowing!
Hey Eli do you put flux before reflowing new hub (chipset)?
my motherboard also have problem, everything is working fine but its it not display anything in monitor.can u give any advice
Can u teach me what to touch with the negative what to touch with the positive? My board turns on can play gta 5 but I think I shorted argb I can get lights to light up with unplugging and plugging argb but the computer then gets problems and will get blue screen and shut down but when I initially plug in argb fan at botten of board it won't have no lights until I mess with it unplugging plugging back in ect
What course did you take??? Please i want to learn also.
pch chipset getting hot in 3.3 volt power rail, is it short?
Hello i have a Gigabyte Z87 motherboard (im not sure on the model i will have to edit this when i know) it powers on but after a few seconds it will turn off, then power back on and it keeps doing this with or without a ANYTHING installed. any idea what it could be and how much to repair?
I have a asus 970 aura am3+ motherboard that i need repaired...how do I go about sending it to you?
One question!? Where can i buy theese parts? I mean u repair videocards and motherboards and u allways got the part what u need, i surched up on it and sometimes i found it to, so tue real questin is which sites looking for theese parts?
I've been wondering this as well, but he actually answered it above: Taobao, Ebay, AliExpress.
hi Eli what diagnostic card you used cant i know it
Stupid question: How do you know where to test the power pins / where each power line runs to on the board?
Great work I can only imagine how advanced you are now. Where is a good place to order the Z97chipset from?
Sir my zotac gtx 1060 3gb mini shows error code 43 or 31 and black screen also which problem inside it and it is repairable or not
Hey buddy, I've been having a problem over the course of the last 7 months, my PC wouldn't post and the CPU_led stays on, it happened first in march for a couple of days, then again in June, September and lastly yesterday. Every time it would be solved differently, like once it worked when I took the motherboard out of the case, another when I reset the CMOS. When it happens again, none of the previous solutions work, and now I'm stuck and have no idea what to do. Please note that the thermal paste is old and dried out but when it was working until two days ago the thermals were pretty alright for a stock cooler. Could this be my problem?
Where did you get the replacement chip set?
Hi Eli.
Can you please make a video about the reballing station. Do you have different settings for gpu and mobo? What settings do you have.
And please make videos more often!!
Golden regards...
where did you get your preheater / bga rework machine? how much?
Which post test card are using?
what did you do at 4:54? where did you make contact?
Wow! Anyway i can contact you? I need help with asrock Z87E-ITX that a transistor blow on but i cant find out what transistor i need to buy to Change it with.
What was he checking for ram power? A coil?
Keep doing this type of video. Very interesting and the step by step vlog is really nice
Oh, wait, It seemed to me, or I just heard "Dosvidanya"? O_о Thx for the video! From Russia with love.
