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

I mean, could be that your psu is failing. Computers tend to use ALOT of power when starting up. It could also be that your hard drive is failing.

I may be wrong, but if it was my hard drive it would give me a bluescreen, right?

Bluescreen is usually a graphics card problem.

This sounds like the cpu is overheating. Can you check the cpu temps? eg HWMonitor

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

Those temps aren't too bad.

Can you run HWMonitor to check PSU voltages?

Since it has been three years i guess the PSU is dying. The quality of that isn't great and was given a three year warranty. Probably time for a PSU upgrade.

Alright then, I will replace the PSU and come back with the results.
