I noticed my computer keep crashing while playing games. Initially I thought it was the new NVidia drivers so I switched them to an old version but that didnt help. I did a cpu stress test and it was fine but the gpu one failed when the gpu reached around 100% load. I used compressed air to clean the inside of my pc but that didnt change anything. The gpu is a couple years old but was working fine until a week ago. Kinda freaking out any help would really be appreciated. For the crash both my monitors turn a different color and then go black and give no input and the lights on my keyboard and mouse turn off.

It could be that your pc doesnt get enough power. Maybe something is wrong with your PSU. When did you buy the PSU?

 

It could also be that your gpu or the PCI-E slot was damaged. Try to put it to a different slot and see if it works correctly
