So about 4 years ago i bought (my fault) a prebuilt computer. It has been working fine till about 2 months ago. I've been experiencing freezes and/or crashes. Most of the time my screen gets brighter and than my pc crashes. Sometimes the audio repeats and then crashes. I think its a gpu issue. But the thing is sometime my pc goes back to wroking normally after freezing. It happens while gaming and while browsing for instance. Ive took my pc apart and put it back together. I've even succesfully flash updated my bios. Didnt help. Im kind of helpless. I tried to underclock my gpu a bit, because i read that that might help. but it still proceeds to crash. Any help? Im trying to sell my pc to uprade to a better one, but i cant sell a broken pc.
Specs (dont hate on the prebuilt specs, i was 12 back then)
Intel i7 7700
KFa2 GTX 1060 6GB oc
Crucial CT16G4DFD8213.C16FAD 1x16GB
MSI H110M PRO-D (MS-7996)
Psu can't tell but its probably a cheap one bc prebuild
