Pretty much what I said in the title but I will try to provide further details.
I recently bought this used graphic card and after solving (thanks to this forum) some troubleshooting issues, everything was working smoothly, I just didn’t had the time to benchmark the card but I could try it in games and it was awesome, both for temperature and performances.
Yesterday, quite suddenly, the PC shut down out of the blue, while I was doing stuff on internet and light working.
I also couldn’t reboot it before switching off and on again the PSU, but this problem did not shown up anymore later. Anyway, switching on the system gave no video output and motherboard VGA signal on. Also, no led on the GPU ever went on again.
Now, actually I’m quite worried (and frankly almost resigned) that the card has died, for no known reason, but here’s what I’ve done.
Disassembled the card in all its parts, deeply cleaned it up and changed the thermal paste (old one was effectively dry) but didn’t replace thermal pad as I didn’t have any and they were in good shape
Reassemble everything and mounting it on the system - zero changes: no video output and VGA led on mobo
To check that everything else was not causing the problem, I switched to my old graphic card (which is nvidia, so I used live USB version to change drivers) and I could get all working - this is what mainly leads me to think the 6900XT is dead
A NEW HOPE
Trying to think what’s left that does necessarily involves the card’s death, I thought that the HDMI port on the GPU could have gone off for some reason, even though this does not explains why no led turns on on the card and why the system should have shut down in the first place. Or maybe, one of the cables from the PSU (not needed for the old GPU) is faulty (even though it is new (the entire PSU) and it was working fine. So, looking for hope and solace on youtube, I just went through this video in which they just switch the BIOS on an apparently dead GPU (with the button present on it, as it is in my case as well), and it suddenly REVIVES!!
To cut it short, simply switching the button doesn’t seem to work, but maybe being able to flash the right bios on the right switch position, could really make the trick. Problem is that I have no idea how to do that and programs needed (as from tutorials) to do it are only compatible with windows.
In the end, is there anyone who has some idea about how to do it, or even better, has done it on his/her GPU?
I would thank anyone for the help and for the patience of reading all this as well
For proof of very high efforts level I report the testbench I’ve set up for the occasion
