hello folks,
i been having this issue for few months, but now its kind a frustating because happening nearly everyday.
when playing any game like maybe coh 2 or x3 tc, after some time the screen just goes black, im able to connect to computer by teamwiever etc. most of the time when that happens, 1 week ago i managed to check device manager from my phone using team viewer. on gpu section my gpu wasnt shown up. it wasnt there.

when black screen happens i have to restart my pc manually by using power button. when restarting after black screen happens, like %70 of the time i see artifacts, a full black screen with few white pixels on it right after bios screen passes. i have to make another restart to reach windows again when that happens.

now im making a stress test with prime 95 and furmark on. its been atleast 20 minutes nothing happened.

what i tryed:

reinstalling gpu drivers, with ddu (atleast 3 4 times) no fix,

fresh windows installation (did today black screen happened 30 minutes ago) also before i reinstall my windows black screen started to happen even when i normally use my pc like copying or browsing.

flashed custom bios to see if its a problem with gpu voltage (some people said they having driver crashes on mid boosts because of low gpu voltage given by nvidia)

i have no idea what causing that? if my gpu is faulty or something im basicly done. i live in turkey taxes + dolar values... jesus, gonna be a pain in the back to buy a new card. and my card is out of guarantee. its been 3 years since i bought this.

hope its a software or psu problem, otherwise.... oh dear....

Edit: forgot to ask, how i can monitor my gpu behavior, crash etc. is there any problem or logs provided by gerforce drivers?
and how i can check if its a psu failure?
 
Similar problems although I cannot even boot now with my HDMI connected to my GPU. I have to boot using dedicated and switch over to my GPU once I reach desktop.

My issues started about 2 weeks following building a new PC. The moment I tried running my mixed reality headset off it the black screens started. Very soon it was doing it in my games after a few minutes. Now I cannot even boot with a display out of my 970.

I am using minidisplay to HDMI.
 


well im using DVI (digital only)

 
UPDATE:
untill yesterday my gpu worked fine, yesterday we had a power problem because of our dying machine. long story short power went down when pc were working. now issue started all over again. as same happening randomly.
gonna ask my friend about his PSU .... or just gonna give him my gpu for few weeks.
