Screen freezes/crashes/bootup failures/HDD wiped

[mckana1234]

Hey, I've been having multiple problems since I moved houses few weeks back. Would be great if someone could help.

My screen freezes/ pc crashes randomly, and after freezing/crashing I get bootup failures. This sometimes happens for multiple times in a row until I unplug my pc for a few minutes. Today my HDD got partially wiped randomly, it went from ~350gb used to 120gb used. I have my windows 10 on my SSD. I've had screen freezing/audio looping problems before, but they stopped after installing SSD.
Update: forgot to add that sometimes when opening games, everything seems fine but after 5 seconds the game screen freezes permanently until restarting computer, restarting the game just repeats the problem. I can still hear everything and my clicks register during this game freeze.

My specs:
GTX 760
INTEL CORE I5-4670K
ASROCK X87 EXTREME3
KINGSTON HYPERX 8GB
WD CAVIAR BLUE 1TB
XFX 450W PRO CORE EDITION V2 FULL WIRED 80+ BRONZE
ZALMAN Z3 PLUS
SAMSUNG 250GB SSD

Anyone? Problem was gone for few days, but today it started again with my game screen freezing first. Everything else worked for few minutes until my computer fully froze. Now I cant even boot up without pc freezing. This same sequence happened before too.
