Guys please: Before you attempt to diagnose GPU for faults, please have the following:
#1 Multimeter
#2 GPU it self
Believe it or not, #2 is often not available.
okay
if artifacts do happen and the windows stopped the gpu(error 43)
is it always the memory? or there are also other factors?
@@angieee-could be the ic controller, or in some rare cases its short mosfets
@@mwhunter2346 thanks
i think this one is much easier to repair that the other 1660s that i have(it was a Galax with no display but with power) cause the artifacting GPU I've mentioned was also a 1660s(MSI Ventus)
Ouch, shots fired!
😂
Dude. I went over the mostfet route… found nothing. Visual inspection looked fine. Then you said… just look at the caps near the connector at the back… what do you know. Solder 2 missing ones and fired right up! Thanks!
Thank you very much, you reassured me. I have a computer that fell on the ground while it was working, and when I turned it off after it fell, it did not turn on after that. When I checked it, everything was normal, but the vga circuit I suspected that it had shorts, but after I made sure I found it a small resistance in vga and not outright shorts
Top video, I hope to find the same kind for motherboards :)
Hi. beginner here. You mention at around 00:40 a video you have on component recognition. Can you link me or give me it's title (I have looked but can't find it) Thanks. I'm finding your vids informative but often a bit advanced. One step at a time right.
This is extremely helpful. Thanks!!
Thank you very much, very informative information and video. I’m trying to learn pcb diagnostics myself as I’m an auto technician but I’m very tech savvy. You’re very smart and again thank you this video has valuable information and I will be using it to help me as I’m trying to get into the IT world and learn everything that I can. Videos like this are very very helpful 🙏
This is very usefull, but I am playing more like with AGP cards, so I would appreciate such tutorial on something like GF6800 which are very often dead. 🙂
I know that soundtrack ... very satisfactory vid :)
hello friend, I have a gtx 780sc evga 3gb P/N 03G-P4-2784-KR like your video card... I have Coil Whine problems when I enter some heavy application like games or renderings. If I change the R22 inductors (6xunits) do I have a chance of solving the problem? Is there a way to find out which inductor is bad or should I replace them all? do we have another solution? thank you this noise is driving me crazy!!!
This is a very good tutorial
Great educational video.. bets out there for beginners.
Nice, thank you!
Thanks a lot for this guide, it's very useful and understandable. In my case visual inspection looks right, but there is a lot of capacitors in short (3 near the PCI slot connector, and 6 at the back of the core), so I suspect it could be a dead core, but since I'm a beginner, what do you guys think?
just here to say thank you!
Thank you, appreciate the walkthrough
Thanks! Useful info. The gpu stabbing video was good too if anyone hasn't seen it.
Is that the one where he drills a hole all the way through the PCB to do a root canal on a rotten VRM, and the card starts working?!
@@RobinDobbie it was an earlier guide he did on what diagnostics he runs on gpus.
But that one sounds good too lol I think I must have missed it. I'll check it out

Thanks, it really helps, i know there are several low coltage rails on gpu, i just dont now which one is which, i just always randomly measures a large capacitor for voltage, i have 5cards here but only got 1card working because lucky enough its just a shorted low side mosfet, the others are a nightmare for me since i dont now where to start at live testing a gpu
How i set up my multimeter to check the gpu?
My 8pin beeps to ground on 6 out of 8 pins :D
hi, if pex rail resistance below 3 digit (possible short), will the core still getting warm? because my dead rtx3060ti core still warm and getting hotter with all voltage present. I want to make sure the core really dead before I use the card as my door stopper.
PEX rail can have low resistance sometimes. Depends on the card. Unless it's 0 ohms i wouldn't immediately assume it's short.
Thanks 👍
ihave a zotac 1060 6gb, all voltage are complete but still noo display and not being detected
I have a b2 error code
Tried almost everything
Reset bios button
And it did worked like normal and when I turned off the pc it happened again
Any ideas how to solve
For every GFX Card there soooo many infos about where is what in the internet. u dont need to know everything. all infos are present. gfx card repair is soooo easy, there is nothing special on it. the most magic happens on the core, so all around is only power, pex and some logic gates, some modfets (thats killed mostly).
Easy going, making money ^^
My AMD vga +Vcore got 5 ohm resistance to grounds. Is it normal value??
My power station is tripping off as soon as I connect the graphics card to it through the 6pin pcie connector.
What could be the problem?
Where does the „global“ or singel enable signal for the controller come from ?
I already replaced a blown powerstage on a 3,3v plane on a saphire 5500 xt. But although i succesfully removed that short i still have no enable signal on any controller.
Also i measured 0.4v on the enable pin of the Vcore controller. Wich is according to its datasheet the fault voltage.
I need to know where the fault has its roots.
Btw all fuses are good and all power inputs are good in terms of voltage.
I honestly dont know what the 3.3v rail is for :D and it might help to know where the enable signals are generated in order to seek for another short.
Pretty sure the powerstage blew because of another issue
شكرا جزيلا طمنتني ، لدي حاسوب سقط على الارض و هو يشتغل و عندما اطفأته بعد ما سقط لم يشغل بعد ذلك ، عندما فحصته كل شيء عادي لكن دارة vga شككت ان بها شورت ، لكن بعد ما تأكدت وجدتها مقاومة صغيرة بالvga و ليست شورت صريح
So I am having a beep at the 12 volts pins, what does that mean?
there is a short circuit on the 12V power plane you are measuring
Hey there! I have a reference Rex 5700XT, that displays, but crashes the system when under a load. I tried doing the steps you said here in the video, but I haven’t found anything. What should I do?
is it because of a limitation of power delivery from your psu? How many watts is it?
@@shaoyangzhang8523 My PSU is 750w. I’ve already ruled out the other components in the PC aren’t the issue.
@@RTC1200your gpu has degraded due to high temps. Try changing the bios to a one compatible with your gpu, or try lowering the clock speeds
@@agsechogd6406 Hm, Alright. I’ll try it out.
@@RTC1200 also high temperatures are the reason why it could crash under load. typically when a gpu gets over 90c it shuts down
I'm getting current shock on my PC. When I removed GPU from PC; it works normally and doesn't give shock. My question is is this because of fault in GPU or SMPS ? Please help : |
Hi, may I ask you, where I can talk / write to people like you? I'm struggling with my gtx 980, which force my PC to restart if 1. I connected two monitors and 2. Start an ego shooter.
Sounds like a software issue. Probably try to reinstall or update your driver's or reinstall Windows if that doesn't work.
Hello i got msi gtx 970 in new to this. I messured everything and thers no dmg or short circuit. but thers no video and Gpu core is cold ( so it's not getting power) Fans are spining..
Probably chip needs reball
I have a PNY RTX 2080Ti that will boot and the screen will come on and I may be even able to run Heaven for a few minutes but then I get a black screen and the Blower Fan turns on Max. I then have to either do a 5 sec power cycle or turn off the main power to get the computer to reboot. I have noticed that I am missing a lot of ceramic Capacitors on the back of the card. I would begin replacing the capacitors but I don't have another 2080Ti to get them from. What should I do?
Have you tried getting a board view for your 2080Ti, finding out the exact parts you need and then ordering them from somewhere like AliExpress?
@@ProfShikari I tried to find a board view on the internet but I could not find a good one for the exact card. It's a PNY RTX 2080 Ti.
@@frankesposito2229 can you not find a very similar one that would be a near perfect match? Lol
I have a 3060 Ti that gives me code 43 so I want to check what is causing it. GPU-Z can read the BIOS, the VRAM frequency, even the driver but not the size of the VRAM. I dont really get artifacting like most common 43 errors, in fact the card works every time I restart PC, it works for like an hour then the screen goes dark and PC restarts. The funny thing is it passes furmark test and gaming, but again it randomly crashes. I suspect maybe is BIOS chip but I have ZERO knowledge of PCB layouts, or how to use multimeter thats why im here lol but any way to identify BIOS chip and how to test it with multimeter? EDIT: I checked ASUS download center for BIOS update on my GPU but it says there are no new updates for it.
Most likely faulty VRAM. Try to run a mats test on it.
If GPU-Z can't read the VRAM size that means the driver is not installed/active
what is the name of that multimiter?
Any
Thank you for the knowledge sharing
all voltage is present, but no display. where do i go after that
I’d say visual inspection of the PCB under a microscope to check for signs of corrosion
the problem here is the chipset beneath it needs re balling to make the surface of the chipset and the gpu has a good conduct
What does a fuse look like I can't tell the difference
Usually they are white while resistors and capacitors are black and brown and they are also marked as F on the PCB instead of C or R
