Question Dead GPU?

[TrueParzival]

Was playing Elden ring on my rig yesterday night. All of a sudden the PC shuts off completely. No Blue screen, nothing just hard power off. Now PC won’t even post. Initial thought was my power supply or motherboard bit the dust. Did trouble shooting by taking everything out and testing to see if PC posts.

After much trial and error, I got my PC to post if GPU is not connected to power. Meaning the 8 pin and 6 pin not plugged in.



Maybe it’s the PCIe socket or cable? so I tried using my friend’s card, it’s a 980ti, everything boots and works fine. So something is up with my videocard.



Did one more test to see if it’s actually dead. tested it on my friends PC, his PC wouldn’t even post. (When power is pressed, fans don’t spin on anything, No beeps, clicks or sounds of any kind including on gpu. I would think that the PC would at least start up but not display anything.



Can’t afford to shell out 1000$ for a new GPU right now... any fix I can try?

The card looks a bit dusty inside, it has a backplate so maybe some dust is screwing around with the circuit back there?



Any tips on what I can try is welcome.



My PC specs

Motherboard: Asus strix

CPU: i7 9700k

GPU: EVGA GTX 980

RAM: Tridentz 16gb ddr4

Power supply: Corsair RM 750

did some dusting and inspected the PCB under the backplate, nothing looks burned out. Still having problems with it preventing my system from powering on.

If you've dropped the GPU into a donor system and it's exhibiting the same issue, then the issue is the part you (removed from your system and)dropped in. You might want to state the make and model of your friend's PC's PSU and it's age for sake of relevance. Sadly you can't repair a GPU unless you're handy with a multimeter and have a myriad of gadgets to identify where on a circuit/PCB the issue exists.

Possibly a short on the card.

Nothing consumer-friendly buddy.

The unfortunate thing is that fixing a GPU is a very precise, very technical, very iffy procedure. Fundamentally speaking, anyone who has the ability to do such a thing wouldn't need to ask the question. I don't mean this is an insult; I've only successfully fixed a few GPUs myself, mostly when there's something obvious like a blown capacitor. It's just a very difficult thing to coach someone through on a forum.

It's a bit like going on health forums. You'll never see a thread telling people how to do a liver transplant, simply because anyone who has the qualifications to do such would not need to ask on a forum.
