Question Computer crashes but sound continues while playing games

[Relegence]

Hi, I've had this issue for a while now I've tried everything I can think of so far.
While playing games the computer crashes with either a white/black/pink screen and the sound continues for a while before needing a hard restart, I've recently taken my computer to a computer shop and he has cleaned every part out, replaced thermal paste, updated BIO's. The only thing I have not done is re-format my hard-drives which I doubt is the issue. Very sick of this happening and causing a lot of stress for myself. Would be good if anyone can help me out. Thanks.

I'm not too good with computers either like taking out parts and such, so yeah

I'm not an expert here, but I had pretty much the same problem for more than 2 months. I had Windows 10 installed, and it finally became stable after I downgraded to Windows 8.1 . Maybe that's not the problem with your PC.

Tell your PC specs, (better edit your main post)
