Hello
No idea what the issue is, i've had this problem before the i formatted my pc (2 days ago) and its still there even after. PC runs fine while i surf but crashes when playing games after about half hour.
Idk if its the HDD or PSU. CPU is at 52 degree while on idle.

i5 3450

1tb hdd
16 gb ram
400 psu Whitebox
