My computer turned awful

[Jacob_138]

I have a K430 motherboard (3109)
I7- 3770
16gb ram
Nvidia 640

That would run games such as League of Legends at 120-160fps on the highest settings whilst playing hearthstone or watching YouTube.

Now my sound doesn't work, my computer blue screens when trying to do two things at once and I get 10fps in League. Any ideas what went wrong? Or should I just kms?
