I owned my own Electronic shop for 20 years in Canada and have been in the repair business for total of 54 year. That was a great repair and shows
your dedication to the customer, thank you for putting this video online. Michael
I think skills like this is a dying art now.
@@procta2343 : but still very much need it
This is why I love this channel. That was a masterclass. Satisfying.
Fantastic breakdown of how to diagnose, never assuming or defaulting, and then repairing a desktop pc. Maximum respect.
Going above and beyond as is standard operating procedure for Adamant IT I've noticed. You're local customers are so lucky to have you and many of them probably don't even know it. Most computer stores would at best diagnose a motherboard fault and then just toss out the existing board. They would then perhaps upsell the customer on a more expensive replacement part with a decent markup, plus probably charge more labor than you did in actually repairing the board. So yay to no needless e-waste and another bravo job sir!
Can’t beat a lunchtime adamant IT upload
47:52 - That "Hallelujah!" moment when you know you've found it. A lesson in methodical diagnosis. Top man!
Hell of a find. Thanks for taking us along on that journey.
I can say with a fair bit of confidence that the misaligned i/o plate and the broken solder joints have the same cause. When the expanding packing inflated, it pushed down on the gpu hard enough to not only bend the motherboard, causing the already substandard solder joints to fail, but it also bent the motherboard tray of the case.
Yep I was screaming this at the screen the entire time. Too much pressure from the expanding foam
@@ve4edj Right from the beginning that motherboard was screaming for attention. There are literally hundreds of copper traces on the bottom of the board that could have been shorting out. If this had been my repair I would have gone for that mobo first. Amateur Radio much? N4RGQ
@@williamjones4483 Traces on the bottom of the board won't short to anything with 6mm standoffs. Sounds like you have no clue.
My thoughts too 👍 still a good watch tho
"Already substandard"?
IMHO this was one of your all-time best videos. You were able to diagnose a very unusual and tricky problem while bringing us along for the ride. I really enjoy troubleshooting videos in general and this was a great one. Please keep up the excellent work!
Absolutely amazing find and fix. Love it when you post gems Like this. 👍
Can i give you 5 tumbs up Gragam? One seems not enough for this video. Oh i have to answer under a post, i cant post on my own.
You should be proud of your work here mate. You're the kind of skilled repairman everyone wishes for.
Well done Graham, good diagnostics, thoroughness in checking the board paid off, most repair shops would have given up and sold a new motherboard. Hope your customer appreciates it, but at least you had a really interesting repair video out of it!!
i think this sort of repair work now, is getting very thin on the ground. Too many shops just want to the quick swop and away, rather than use skills on repairing, like people used to do. I fixed my PC speakers, with a soldering iron. That was thanks to Markus Fuller, who did electronic repairs, so a quick look at two mins if that with the iron and good as new.
Though after he found out it is a chip on the motherboard not any other part that is the problem unless he offers logic board repair services which he does. As most don't and only do part replacement not chip repair they would replace the part that they found to be faulty.
Times money mate. A board is cheaper than the diagnosis cost
@@DJIInLondon As he seems used to finding the place the error is made it was quick. As most logic board repairs use cheap chips or no chip in this instance it really depends on how quick are the employee at finding the error and how expensive is the board for which one is objectively cheaper after all costs are accounted for.
You still have to go through the majority of what he did to find the part that needs replacing as blindly going through a list will take more time then to do simple diagnosis like he did to get to it is a motherboard issue.
@@procta2343 Well it depends, if it was in warranty, i would recomend use it before soldering...
I'm not a computer Geek, but I love watching your videos. You're amazing, love to watch your diagnostics, methodical approach, which goes a long way towards explaining why you're so competent & successful in your career. Congrats!! I look forward to your next video.
i do believe the aio cooler heatsink is oriented in the non recommended way could get air stuck in the pipe.
@@josephmeholick1300There is always that one guy who thinks like you.
For the 10.000th time it doesn't matter, if there is an air pocket stuck in the pump housing he can just rock the case back and fourth until it has moved to the radiator.
@@AutodidactEngineer Well this is in ideal position is one where the pump is the lowest point in the loop but as you say it doesn't matter, it this case you would hear gurgling but nothing more than that.
The only thing I will say is that as the coolant levels get lower then you'll get more air working its way into the pump which can damage the pump, some AIOs have fill ports though so you can always top them up. I mounted my AIO in the top of the case which is the best place as you'll always get coolant flowing through the loop, but again as you said, it doesn't matter.
Intermittent dry joints were the bane of my life for almost 40 years of electronic repairs so I am pleased to see I was not the only one. I used to suspect dry joints early in a diagnosis as it was usually easy to fix them. Well done to spot them.
Your commentary as you continued on with your repair was very entertaining, worth continuing, and amusing. Carry on, well done!
Amongst your viewers, I’m sure that I am not alone in stating I enjoy your longer videos more as there is always more interesting trouble shooting. Great upload!
That noise at the beginning might well be the most relatable reaction I've ever seen on UA-cam.
The NVME is maybe connected to the chipset in stead of the CPU. There are two slots closer to the CPU that probably connect to the CPU more directly. I see you fixed it at 55:00, good job.
Tons of electronic repair videos on here but this one really was most enjoyable to watch. When you nudged those pins and found them loose, that's what it's all about. Looked like the whole of that end of the socket hadn't been pushed down before soldering at the factory Great stuff!
Nice! It is so much fun to ride along with you as you step through your diagnostic process. That was a brilliant bit of sleuthing. I can honestly say, as a Ph.D. biochemist, I am humbled by your analytical skills.
That eureka moment is the happiest I've seen you for a long time Graham. Nice one 👍
That was really interesting. Loved how you patiently narrowed it down to some loose joints that also would explain the intermittent fault dynamic. Love this.
prefect example of the passion for electronics.. Great Job!
I build gaming systems and I am totally impressed by your troubleshooting skills. Methodical….on point…..and your soldering skills are far better than mine.
I so very much appreciate you actually looking to FIX things. instead of replacing faulty parts. you replace faulty parts of parts. I'm sure its more work but I do enjoy the whole "not throwing it away" thing. Well done
Brilliant job, Graham. Well covered with all of the appropriate camera shots. Very enjoyable to watch.
One of the most satisfying repair vids I've seen in a while. The only bummer is that the owner will never really understand what you did. Most repair shops would have just stopped looking as soon it worked in another slot.
Yes another LFC video. Absolutely love watching this channel and the diagnosis process. Started watching the Twitch channel too which is great. Many thanks for the videos and streams.
That was an amazing video. One of the best. Your detective work is super impressive and I'm sure you will have one very happy customer.
Excellent find, repair and riveting video. The customer should be thrilled with your work! 👍😎👍
This was a great watch, Thank You very much for sharing this! I learned something new.
awesome work, loved how you diagnosed the problem and came up with a fix
Loved this vid. Wonderful to see you find such an unusual fault, but even better that you worked out the fix, did it, proved it and we all learned something. Respects
Best video yet. from start to finish, a great overview of diagnostically understanding an issue leading you to the fault. An enjoyable hour of viewing
Well done Graham. Amazing piece of troubleshooting and repair.
Outstanding diagnostic work! Thanks for posting. 👍
The most satisfying repair, well done Graham 👍
I loved your diagnostic process on this one! All the steps were very logical and concise. Loved it, well done!!!
amazing to see you follow the traces and just kinda figure out the schematics...that stuff blows my mind...great repair and excellent to see a professional share their step by step approach and thought process...
awesome mate, that's the best diagnostics and fix i've seen, and i've seen so much
Excellent video man! Was very impressed by your methodical problem solving.
Excellent job mate! Well done. Really good video.
Great video. nice to see thorough testing and problem solving, subbed for more content
Very instructive, and exciting as well. Good points made about the parts choice too. So well done, as always!
Super legit repair and I love your channel!
Great job on the full hands on fix! Really entertaining and informational! Keep it up! Big subscribe!
Wow I love how you went above and beyond for the customer with the fixes at the end! Nice diagnosis and repair.
Fantastic diagnosis and repair! Basic steps to diagnose today's electronic problems are too often bbeing overlooked or skipped for the all mighty buck. Thanks for taking us along and take care!
Fantastic video!!! Love your methodology once again. I must say that watching your videos has given me the confidence to transform the way I approach my repairs to a even higher level. Take a bow and keep up the excellent work...respect and regards.
Such a damn good video! Keep up the great work! :)
Very cool! Thank you again for another educational experience.
Nice! That missing fan was the give away. On a side note, both of my posts have involved fans :)
Best video in a while. Keep them coming!
As others have said, this video goes down as one of your best. Great commentary, logical diagnostic process and following through with the fix. Good to see the “Solid” test on the pins gave up the manufacturing fault.
Great video - loved the methodical approach and the absolutely glorious moment when you find the fault - top stuff Graham.
Long time follower. This one was one of the best repairs. Very nice.
That was super satisfying! Awesome stuff.
Fantastic work brother . Love to see you work it through .
I had a similar issue that only appeared when PC was standing up on feet but once I tilted the case on its side , The problem went away .
Thoroughly enjoyable video. Great diagnostics and glad to see you got it up and running.
Your conclusion at the end was perfect for me, particularly if the PC was still new as it is so much less hassle to just get the motherboard replaced. Big kudos for finding and fixing the fault too. Loving the video's, Graham. Keep up the great work!
Great job ,great problem solving. Loved the vid thx.
Excellent video! Well done, Graham. I enjoyed that
I thoroughly enjoyed this!🍻
Great work!🍻
great analysis and great repair, Graham. love the video. 👍
Great diagnosis on this one! Loved the video
One of your best videos! well done, great analysis
Another brilliant video, love watching the podcasts on a Saturday
Good job on this repair! I definately learned something here. Thank you for all you do!
That was amazing, you're brilliant man. This episode in on fire 🔥🔥
That was a great example of honing down on the possible problems until you find the source. Makes sends that the problem was intermittent, given the fault. Very enjoyable. Cheers!
Great fix and what an adventure! Amazing!
Great video, and one heck of a find and fix Graham!
Great fix Graham - enjoyed the troubleshooting
Very cool! Glad you didn't give up on it!
that was an awesome job! congrats! thanks for sharing!
This is the best repairs channel on youtube, great analysis and find
Phenomenal find! You deserve every bloody penny from that fix.
Superb video - a really interesting journey. Nice, super sharp, probes that you were using
Adam, that was a great repair! Learned a lot about PCI-E slots. Thanks!
very, very professional diagnosis, thank you for doing this for us.
Fascinating watching you work!
Loved watching that repair. Brought back good memories of older times. Congrats on repair.
Impressionnantes compétences et savoir faire. Fente de GPU, entretoises de carte-mère, cablâge d'alimentation GPU et repositionnement correct de SSD, une réparation 4 en 1. Bravo !
Impressive skills and knowledge. GPU slot, motherboard standoffs, GPU power wiring and correct SSD repositioning, a 4 in 1 repair. Bravo!
Those kind of faults are super common on PC with cheap boards and heavy(usually expensive) GPU's builded by SI .They probably didin't put the right amount of foam to mitigate the card wiggle during transport, and the weight alone of the card started pulling apart that PCIE x16 slot .And the resistance heat build-up from bad pins contact did the rest.
Sick find though, and i hope the client knows he is leaving with a better builded PC than the one he paid for originally.
dude good job! I love the videos, please keep up the great work! :)
Great video, huge amount of useful information
I love your methodical diagnoses. Good Job!
What a great video...very complete diagnostics down to the electronics level. Thanks for sharing.
Excellent video! Well Done!!

Wow that was entertaining. Well done. Just great service Adamant IT.
brilliant deduction adam love your work! always look forward to your vids learned alot today
Brilliant! That is some next level pc repair, anyone else would have scrapped that MB. You not only did a brilliant job but you also saved the customer some money and we all learned something too.
Great content Graham, loved it👍🏽👍🏽👍🏽👍🏽
Best diagnosis dude! Keep up the good work and yes I did learn something!
Great video and a job well done thoroughly enjoyed watching the whole thing.
