Hello everybody

I hope I posted on the correct thread.

After I start playing a game, if the game its "heavy", it usually takes 10 minutes and if its "light", maybe 20-30 minutes and reboots! This started about 5 months ago and since then I havent played any games.I thought of buying a new graphic card cause I thought it was a problem starting from my graphic card (GeForce GTX 760) but after having second thoughts because few days after the problem started, I noticed a sound coming from the computer, like a "fan is turning off" every about 30 minutes, without runing any games.
I downloaded the Heaven Benchmark cause I wanted to check the temperature and there goes the mystery. Custom settings the max temp goes to 68. But when I choose "Preset: Extreme" and I press RUN, the pc REBOOTS!

Any ideas any of you people??

Intel Core i7
Nvidia GeForce GTX760
Corsair Force LS SSD
2x4gb ram

Nothing throttles before crashing. Everything sound normal actually.
 


I would normally say the PSU.
