Recently my friend wad cleaning out his PC when his cat pushed his GPU off the shelf and hit a table coner, luckly the table coner hit the fan and shroud and not the PCB (it's a EVGA GTX 670 Blower Style) and destroyed both the fan and the shroud, even broken one of the heatsink fins. The GPU still works fine so he gave it to me and asked me to try to repair it. I went on ebay and bought the excact same card for $11 on auction as it was "parts or repairs" as the card was faulty but all I needed was the fan, shroud and heatsink, no more details on what wrong was with that card except that it was faulty.
Today I got the card and decided to test the card in my test bench incase it works, I did get signal and no artifacts, installed latest drivers and started benchmarking it, after about 10 minutes, the card started overheating (it reached 98c) and locked up (From looking at the logs, I was doing another things while it was benchmarking) so I took off the cooler to find out someone replaced the thermal paste with a thermal pad :/, I changed that out for MX-4 and put it back on test bench, now the card was reaching maximium 66c.
But roughly about half an hour in I got a black screen, the audio was still playing thru speakers. I test benched it another 3 times and same results, roughly about half an hour in, I would get a black screen but the card was still outputing audio. Tried multiple things, un-installing and re-installing drivers, trying older drivers, test benching the GPU in my personal rig that I use daily without problems, so I decided to play a game and see if this happens in games, and about 15 minutes in, I got a black screen in GTA V and about 25 minutes in, I got a black screen in CSGO. Eventually I underclocked the GPU core by 40mhz and that fixed the black screens, I ran the card in the same test bench with the same benchmark that before and no black screen after 7 hours.
Since the card gets black screen unless it's underclocked on GPU Core by 40Mhz, is there anyway that this can be fixed, or what could be the cause of this? Could a custom BIOS flash fix this? I have a waterblock for this 670 that I have laying around so it would be nice to put it on and sell the card for small side-profit. Thanks for reading
