+ DVD drives from old comp.

Everything was working fine, I still got my OS, and my pc performances was great.

Today, the pc suddenly having distortion. So I turned off my computer, then off and on again, until the pc finally started working.
After a bit, the screen suddenly turned blue. I decided to do the same. However, the screen remained black.

My OS is window 7 professional btw.

My GPU fan is working, to make sure, I tried to push it a bit further. I don't think it's halfway.
