Yesterday my computer shutted down without warning. I don't remember what I was doing, but it was nothing special. After that, he began to shut down more frequently and it came to a point where I saw the Windows logo for one second and it shut down again. After more than five shut downs without warning or even BSOD, I gave up.
This morning I started my computer again and it shut down again. It restarted and it was stable for a couple of minutes, then it shutted down again.
Right now it is stable, but if I open a game (like CS: GO) it shuts down again. I don't really think it is a heat issue and I ran HeavyLoad for more than 5 minutes and it didn't shut down.
I have this computer for almost 3 years and it was custom built.

SETUP:
Intel Core i7-2600
Asus P8H77-V LE
Kingston DDR3-1333Mhz 4GB (x2)
Kingston SV300S37A/120G (Main Disk)
Western Digital Blue 500GB Sata III 16MB WD5000AALX
Corsair Builder CX600W v2 CMPSU-600CXV2EU
EVGA GTX550 Ti GDDR5 2GB
Windows 8.1

Yesterday it was at 40º-50º while playing. Today I ran HeavyLoad and it was at 74º and it didn't shut down.
