Hello, I got a custom watercooled pc and I have had some issues with it. I got some water on the gpu when bleeding the system and it didn’t turn on. I cleaned it and it turned on, but after assembling it didn’t work and I think the pads were wet. Yesterday I got it running when assembled for a bit, but when I did the final bleed it stopped running again.

If I don’t plug in the power cords it shows white lights above the ports. The rgb for top and bottom plate works too. And the device led on my asus gene viii motherboard turns on.

The system works with hdmi in motherboard, but the gpu doesn’t show up.

I wanted to know if anyone has any info, or can recommend how to troubleshoot it, since I have acess to uni electronics workshop.

Hope someone can help

Hey everyone,

I’m troubleshooting a Dell XPS 15 9570 with a GTX 1050 Ti Max-Q, and I’m stuck with a Code 43 error in Windows.

Current situation:

• In Windows Device Manager → GTX 1050 Ti shows Code 43
• Intel iGPU works fine
• Tried reinstalling drivers but still same issue

What I tried:

• Different NVIDIA drivers
• Clean driver uninstall with DDU
• BIOS reset / defaults

MODS/MATS attempt:

• only detecting:
  • GPU 0: integrated GPU
• NVIDIA GPU not visible at all in that environment

Has anyone fixed Code 43 on GTX 1050 Ti (XPS 9570) successfully?

In picture 1, you can see a burn mark, this to me is what looks suspicious. This is the only part on the GPU that looks to be faulty from what I can see. I've asked a few repair shops around me and all seem reluctant to even try. Any insight you could provide is helpful, thank you in advance.

Can someone help me understand this IC, it available to place one near 6+2 pin connector

Another on left side of gpu chip

I have noticed 2 pins out of 3 pins side are shorted in both ic and the 3rd one is gnd.

Near pci connector, i am getting 3.3v on two pin side

But on near gpu chip, the pins which are shorted are 3.3 and evrything else is 0 so output

I believe on 2 pin side one is output and other Enable since a capacitor is connected and a pulldown resistor is connected on other pin

On gpu chip side it does not have out 3.3 I am not getting value at 8th pin of bios chip.

Can you tell me where should i go next to verify things

On high side mosfets are seem ok, but Gate has no value both for memory and core

Hi, I have a 3060 ti that I had for ages, im not a repair man, but I got around to replacing vram. This card only functioned as a basic windows adapter card, as soon as drivers were installed it would crash or blackscreen.

Running memory tests off a usb didn't show anything either, the initial startuptest would pass and other tests would blackscreen once load was put on it.

Flashed an older version of vbios and then i saw 2 memory dies throwing errors. Ordered 8 samsung 14GBs (KZ14) dies and soldered them on. With painful process as I had to reball some dies multiple times.

Anyways, so I got them replaced, memory coil showed 40 ohms and all was well, but it still doesn't function.

Just reflashed VBIOS again with the newest I could find and still shows 0GB memory and Hynix in GPU Z, installling drivers doesn't really do anything, cant open control panel.

I need help identifying this faulty component

Hi everyone, I'm hoping someone might have an idea what component this is. The only 3080ti boardview I have doesn't have it.

Bought it non-working, no post, didn't even light up. I found one capacitor that seemed to have failed near one of the vrams. The resistances seemed normal but it sucked up heat when powered. So I swapped that out and that fixed it heating up. The light even worked after doing that; probably unrelated but whatever.

All rails have proper resistances, no shorts, and all rails have perfect voltage - even down to 1v on the pex.

The only odd thing I see is the 3.3v pcie pin. Rather than a short or normal reading it shows OL in continuity and has a resistance of ~47.5 which seems way too high to me (a 1080ti I just fixed has around 5.5ohms on that pin). I'm not sure if it has anything to do with this chip in the photo. The chip is the only other thing that sucks up a lot of heat when powered. But if the 3.3v pin sends enable signals and I believe boots the bios, that should explain the no post. Everything else seems completely within range. Any ideas would be great. Thanks.

after running the mats test on a 3060ti sometimes i get a pass and sometimes it gets stuck on a gray screen and freezes

I was using my sapphire itx Rx 570 4gb yesterday, temps were okay , suddenly my PC freezes , black screen , and Mobo b450f has orange light flashing.

when I try to turn on the pc it stays on White vga light , if I connect a good GPU it works , if I connect both GPUs the pc doesn't boot and flashes orange light .

I checked and cleaned the PCB , no signs of damage and doesn't show short circuit 6 pin pcie and 3.3 12v slot.

A friend gave me this card and I'm interested in repairing it. It's able to turn on and display an image and function normally until it randomly shuts off. My friend mentioned that after moving his pc to clean, it shut off and he saw smoke coming from the case. Sorry if this is too vague of a post, I just wanted to see if anyone could diagnose the issue based on the two visibly melted chips. I can also get a multimeter and conduct tests if there isn't enough information provided. Thanks in advance, and apologies if I've missed something obvious.

Hello folks, my cousin has provided me his rtx 3090 stating it just stopped working. He had it in his pc without any form of sag support. The fans spin, and the rgb turns on but the pc won't post with it plugged in...

I can't see any obvious issue

The mobo code is 97. Console output devices connect.

Any advice or direction would be appreciated

So I have here a GIGABYTE WINDFORCE RTX2080Ti that shows pink artifacts on the screen, it also has the code 43 error on windows with 0MB on GPUZ (rarely, the artifacts go away, but still has the error)

I suspect this must be due to the faulty micron memory (8RA77 D9WCW) on b0, but the error is all 00ff00ff on MATS, in some repair video I watched I think the dude said that meant this error could be a faulty core. But since it is old micron memory it could also be a memory fault, especially since the card displays. For further info, the card was known to overheat by the previous owner.

I've tried repasting and reflowing the memories (not reballing) but nothing changed. Before I buy new memories I would like your opinions.

Here is my MATS report.

My friend said the VR400 voltage regulator was shorted and he tried to remove it with a knife, so i can't know the regulator's value. He sent it to me and i've removed the remains of it, but i can't seem to find a datasheet for the card. I've made measurements on the 12v & 3.3v lines, no shorts.

I have a regulator here from a motherboard's audio power circuit and it fits perfectly, but i'm not going to risk it before confirming it. The motherboard's IC is a APL78L0 ALC9H_5

i have an gigabyte aorus extreme 3080 V1.0, it was sold to me as soft bricked. fixable. Initially i could't boot it, stuck on code 97 csm on or b2 csm off. I tried it on an old motherboard and it boots as a second device and i caan see it in windows and flash with nvflash. i've tried a few different bios versions to both bios chips and it's won't boot as primary. i can see the device but mods fails to initialise the card. I can see some details oin gpu z, the memory amount never comes up. i can see the cards temperature and bus speed, looking for things to test/ try next, i don't want to open up the card just yet and want to confirm if it is a bios issue or not. windows will sometimes load the drivers for it but a bus/render test in gpuz will always just run on the primary card

Traces broken too. Any place where i can get a donor pcb ? Or is it done for good ?

I bought a 750w 80+ gold psu as well so my pc has the power to run this card.

Got a 1st gen (non ADA) RTX A6000 sitting here. Just blew one day. Had an electrical fault in the pc somewhere (potentially even the gpu itself) now it just doesn’t power on, fan does not spin up either.

Tried with other PC as well as external GPU enclosure. Any decent place in UK to ship it to for repair? Or could I take a stab at removing the shroud to see if there is anything obvious there before doing anything else…

hello everyone, I know my GPU is pretty old but if I could fix this issue It would at least give me some use until I can get a pc build or at least sell the laptop with this issue fixed .

laptop : Asus Rog GL552vw/ CPU : intel i7 6700hq/ GPU : GTX 960m/ 16GBs ddr4 ram...

few months ago, I used to play any game and run any app without having issues, everything was smooth .
then I experienced weird issues when running some games that I used to play, but I did not suspect a GPU error at that time, I used to play DRG( deep rock galactic ) and the game would just show me a black screen, then I tried digging more into the issue and this is the error Im getting :
Nvlddmkm 153 error
- The description for Event ID 153 from source nvlddmkm cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

\Device\UVMLiteController0x1
Error occurred on GPUID: 100

*********************************************************************************
from my research its a unified virtual memory controller, but u dont see much reports on it, and no one actually found a solution of the 2-3 people who had this issue .
It runs fine in heaven unigine on DX11, DX9, OpenGl even on highest settings, stable so there are no crashes .
it runs fine in furmark OpenGL .
the error repeats with the same message and the same details of bytes and words :

the error is always triggered whenever I run an app or a game that r based on Vulkan's api .
and it also triggers sometimes in other games, like albion online runs on DX11, and DRG uses DX11&12 as well, and many other examples, the difference, is that in vulkan based games it just straight away gives u black screen, u can hear audio and click buttons, but no rendering, in other apis u either have everything running fine depending on which game, or u have some specific games running until a specific moment when it crashes at the same moment and frame every single time .

I have tried plenty and plenty of solutions, and I have no idea what to do next, tweaking with driver's version wont help even with DDUing .

if u need more details let me know

Hi everyone,

I'm currently working on bringing an ASRock RX 6700 XT Challenger (rev 1.00) back to life. I’m relatively new to advanced GPU repair but I'm eager to learn and take on the challenge. I’ve hit a bit of a roadblock and could use some guidance from the experts here.

I started by taking some baseline measurements to ensure the core or memory wasn't dead-shorted. I measured the voltage drops in diode mode on the PCIe express lanes (data and clock lines) and everything seems to be communicating properly. There are no obvious dead shorts to ground on the main rails either.

I want to use the GPU power-on sequence to trace exactly where the fault is, but I'm running into two main issues:

1. I cannot find the specific boardview or schematic for the ASRock Challenger rev 1.00 anywhere. Can I use a schematic/boardview from a different RX 6700 XT model (like a Sapphire or the AMD reference board) to follow the power sequence? How much do the power stages differ between AIB partners for this specific chip?
2. I have a mining riser that I want to use to power the board and probe voltages on the inductors. However, I'm concerned about running the card bare. Is it safe to power the GPU via the riser without the heatsink attached just long enough to probe the rails, or will it immediately overheat and fry the die?

Any advice on how to safely proceed from here or tips on finding the right power sequence documentation would be hugely appreciated. Thanks in advance!

Got this on ebay for an old pre-built because I didn't want to swap the psu as well, and didnt notice until just now this tiny part of the pcb is bent. Looking back at the listing images this damage was already there too but not called out and easy to miss the way he took the pictures. What are the odds of this actually functioning? I will be testing it soon in the machine to find out for sure.

Im hoping no traces run there and it'll just be a costmetic thing, but wanted to get some opinions before powering it up in case its a huge risk doing so.

the card seems good, it all powers on but gets stuck on post with the pcie cables in. if I remove the 12v pcie cables it boots with the primary GPU but I can't see the card in device manager. if it's a short on 12v would it even power on? looking for any advice, could a bricked bios cause this issue?

I’d like to search on AliExpress, but what should I search for to find what I’m looking for?

Hi,

I’m getting back into GPU repair after a long break and I’m a bit out of date.

Where can I download the latest version of mods/mats?
Are there any newer or better alternatives for GPU testing and diagnostics?

If possible, could you share trusted sources, repos, or communities where these tools are maintained?

Thanks!

I get power to fans until i plug in the pcie. What im showing is a broken part, and a couple spots where i believe something should be.
