Question Black screen

[aztetic]

So basically i had this random black screen issue since ages on my old pc and as my gpu didnt crash during a stress test for good 5-10 mins, I thought it was some other part but now I changed my mobo ram psu ssd all almost new and I still get randim black screens after an unknown time period so it indeed is my gpu. Anything I can do to resurrect it out? Its still giving display for some time cause. Temps are between 40-70, kinda low on budget cant afford a gpu rn.
Specs:
i5-8400
8gb ram
H370 hd3 mobo
Thermaltake 530W SE psu
Rx 550 2gb

You can try checking a new video cable, run scannow to check for corrupt files, try factory reset on your monitor, try setting your windows power setting to high performance. Check your screen saver settings to make sure it is off.

I have checked everything, my OS is new, PC isn't crashing on stress test but is crashing when I launch games which shouldn't take much of GPU. Anyone who has experienced this and fixed this?
