Question really wierd problem with a gpu

[LeviKazama]

Hello to all, i have a really wierd problem , and i m not an expert into the things, my thing is i have an GTX 970 SSC Evga, it runs for a bit then crashes, it goes a black screen/or sometimes the windows 10 color and freezes like that, but the catch is , i tested it on my brother pc, same thing happend, tested on a friends pc same happend, but this friends lives in other city, and took about a month to get the vga back ,when i got it back i cleaned it with an contact cleaner and tryied it up, i played 4 days on heavy stress ( Div2, mafia definitive, RDR2,BF4, ) nothing happend i thought that it was a miracle from the cleaner but then it crashed , and then it started crashing the same time it did back at first, then i noticed that the time it was off pc , it made the time it took to crash bigger. what could it be?
things i might find important to note: I already runned an gtx 770 with no problems, a gtx 650 ti, a r7 360 all of those with no problems, i have and corsair CX750M psu , and an i5 2500

if it is crashing with other systems as well, it is GPU problem. try checking GPU temperatures during use.

probably it's life already nearing it's end.

Its normal temps, never above 75 C

Sad ;-; , right on CP77 realese , i was thinking maybe a capacitor as its de-charging when the board is off , and "when it gets charged again" it crashes, but idk how they really work
