Not that long ago, I got a graphics card from a friend and decided to test it’s performance in MSI Kombustor, after the first five minutes I got a lot of artifacts on my screen and needed to restart my Pc ( screenshot below ). A day before that I checked the graphics card for any physical damage and changed thermo past (screenshot below). What could be the problem, and are there any possible solutions besides buying a new graphics card ?
