r/GPURepair

Its not being detected by task manager
But its being detected by bios and device manager
Im devastated i just got this laptop (No warranty) Its throwing this yellow exclamation mark.
I tried drivers reinstalling but didnt work.
It was working fine this morning i came back home after some time and when i booted it was all black.
Then rebooted saw this artifacts and it booted in windows using igpu.
I hope Gpu aint dead
Spects:
Срu: 17-13630Н
Ram:32Gb ddr5
Gpu: RTX 4070
(Sorry i couldnt screenshot)
Please help.

Hi all, I have a Gigabyte 3080 OC that I bought from a customer of mine. Didn't realize how badly bent it was. I've had to use a block of wood to keep it propped up to display out. When the connection isn't right it'll prevent my accessories from powering on so I always watch my mouse or mic to know when I've angled it successfully to boot lol

I decided to try Nvidia MATS to see what was wrong and even scanned the board under a scope to check for any board cracks but saw none (not that doesn't mean there's none) and decided to use a mining riser. Well let's just say it exploded a capacitor when I powered my system on. Mats didn't work even once I managed to get the igpu to post as it failed to see the card and I never could get it to post via the GPU since last night.

It's not the PCIe slot as I've tested multiple boards. Only displays when the right amount of upward force is applied lol

I'm going to check for shorts on 12v and I do have a scope, forgive me if I'll be shunned for not doing voltage / resistance checks ahead of time. Haven't fooled with GPUs until this one so any advice or suggestions is very welcome.

If more is needed let me know and I'll update asap.

this gpu crashes and blanks screens when loading into windows. could it be a bad ram? its such a new card though.

PC recently powered itself off, on reboot smoke started coming out of the GPU. After having a look, this cluster of components shown seems to be the only area with any visible damage. I don't know anything about electronics so I have no idea what this is, and any sites with diagrams seem to be paywalled.

This Saphire rx 580 nitro plus is having issues , it sometimes gives display and it looks like this when it does ,Is this artifacting / vram issues? or could it be just a bad/mismatched bios install?, the repair guy said it might be the qrong bios installed , it looks like bad vram to me , any help or insight would be appreciated

So i got these 3 gpu's for £5 at a car boot sale / flea market and im not sure if they have water damage or if its just dust or grime on it can someone help me identify this? Thank you!

1. ATI Radeon HD 3450 256MB PCI Express x16 graphics card

2. HP AMD Radeon R7 240 2GB DDR3 low-profile PCI Express video graphics card

3. ATI Radeon HD 5450 1GB (Cedar)

Hello! Got this GPU off a friend for a good deal so figure I’d take a stab at fixing it.

Currently, PC will power on and POST with the card installed. However, the card itself has no display out and appears to not be receiving power (there are 4 red LEDs by the power connectors that turn on). Using iGPU, the device is not recognized at all.

So far I’ve tried measuring fuses to see if any are blown. The 3 by the 8-pin PCIe power connectors are fine (F6502, F6503, F6504). The other fuse I found on the backside (F6501, circled in red) seems to be blown.

I measured some of the resistances to ground on the PCIe connector pins as well. All the 12V pin seem to be fine, reading thousands. However the 3.3V pins seem to be shorted to ground (about 15 ohms).

This is where I’m a little more lost on diagnosing this (or if it’s even salvageable). Not sure where to go next, what should I check?

Hey! As mentionned in the title, this is my very first time repairing a GPU (or any motherboard for that matter), and I'm going in a little blind if I put aside the dozen youtube videos I saw.

I gave it to a friend a little over 3 years ago for him to test his PC's performance with a higher end GPU, and when giving it back to me just landed on a black screen when booting up. He was honest and admitted to spilling something on it, but after a quick shutdown and rest, ran it again and noticed it worked just fine.

When I got it back, the fans spinned and all, but the white led signaling a GPU failure lit up on the motherboard and the screen remained black.

Since I have some time ahead, I decided to give fixing it a try depending on how easy it would be to get it running again. I just removed the heatsink and did a quick visual inspection. I immediately noticed this little capacitor near the PCIe that was just floating, and with a small nudge realized one side took off and the other held by a single thread (which could be from corrosion, not sure since the area seems relatively clean aside from the solder being brown).

I know that a removed capacitor is most likely responsible for the issue, but I was wondering if there was a way to make sure nothing else was damaged. Most videos I saw usually checked for a faulty fuse near the PCIe and pins, but I can't seem to find one on my GPU and can't find a schematic for that specific model.

Would love to hear some tips on what would be the safest way to check if the capacitor is dead, fix it and check for other possible damage.

Hi guys!
I just had to troubleshoot my brother's GTX 960 GPU that's faulty, running Roblox and PCSX2 for about 5 to 7 mins in the game, and bamm! the display goes black :(
Also, when the display cuts off, i heard the HDD are going spin down and spinup again, windows still loads.. still wont display until forced restart by long pressing the power button.

Checked event viewer and reliability monitor, has dwm.exe crashed along with the NVIDIA driver.

i have swap the motherboard and playing with memory sticks frequency, but with the same GPU and still does it. Lastly, i tried different PSU (from MSI A550BN to Corsair HX1000i), comes to pressing the power button, and what i got here... the GPU getting burnt 😭😭😭

for more context: this GPU initially still displays normally, but at random times it crashed the dwm when still using the 550W PSU, but blow up when using the 1000W PSU.. is this a GPU problem or the PSU too big for the GPU?

thanks to that OCP kicked in, other PC components are still safe!

what getting smoked is rows of filtering inductors on 12V PCIe power input. checked the resistance to ground, got 37 ohms (very low). all rails (PEX, 5V, 3.3V, and 12V PCIe slot input) seems normal, and has high k-ohms ratings, i also checks the memory MOSFET, got 45 ohms, and NVVDD (core) is on 7 ohms..

does this card still have chance to live again? thanks!

I am trying to find the root cause of the failure of my friends gpu. He was using pcsx2 and the pc crashed. After this the gpu is not allowing the pc to boot and the pc was booting only when the gpu was removed. Board is booting with another gpu. When the faulty gpu was connected in another board the result was the same.

I have now disassembled the gpu, cleaned with IPA, there were no burn marks, no missing components. I tried checking for shorts and not able to find any.

Can the experts here guide me with trying to identify the root cause ?

Hi guys I'm repairing the 3080 ti founders edition.

It has a short on the 1R0 resistor. But it not the mosfet as I removed it and the short is still there. Alo I desoldered the resistor and the short is on the mosfets side even when mosfet is removed. The memory resistance is around 50 ohms so it should be fine. But help me identify where this line is going as I can't find a boardview for this gpu.

replaced a burned drmos, but now the marked cap is showing only 1.4v, but it should be 12v. everything else is 12v. not sure what would cause it drop to 1.4v.

A friend of mine got his rtx 3060 fried after one of our other friends turned off the power strip in which his PC was plugged into.

On start, the rest of PC would turn on, fans spin, RGB lights, but the GPU wouldnt display video and the GPU light on his mobo would flash

I confirmed it was just the GPU as I tested in my system and it same issues.

Any chance of fixing it? Sounds like a 12V short but im not that qualified for GPU repair.

Hello, I apologize for my perhaps immature question, but please stop worrying me. You see, I've had the BC250 for a while and wanted to use it as a secondary PC. The thing is, when I inspected the motherboard...I found a crack in the GPU core, and I was worried it wouldn't work. Then I restarted my mining system and... it worked! But I haven't tested it with Windows or anything with better graphics,Do you think I should still try, or am I overthinking it? University took up a lot of time, and I couldn't concentrate much on it, and I don't know if I should worry about how little I spent...(If you don't understand something, it's the translator's problem)
