Pc crashes while gaming

[WarMachine544]

Hello,
I have recently installed a new motherboard and processor, here are my new system specs:
ASRock Z68 Extreme3 Gen3 -Motherboard
Nvidia GTX 460 -Graphics card
I5-2400 -Processor
Rosewell Performance series 600w (rp600v2-s-sl) - PSU,
G.SKILL Sniper 8GB - ram

My pc runs good and fine for hours, but then i want to play a game after about 1 hour of game play the PC reboots itself and it seems to be cool not hot at all. This happens on Dota 2, TF2, etc

after checking the logs I see nothing wrong with the drivers. I also checked HwMonitor and saved the monitoring data to a file, problem is I don't know how to read this so i will post it here.

Hardware monitor Nuvoton NCT6776

My primary suspect is the Rosewill PSU.

Try a better power supply.

I suspect that HWMonitor is doing a bad job of monitoring PSU voltages. That is not uncommon. Your voltages are obviously OK, because your system boots.

may be there is a problem with your gpu..try updating the drivers..remove and then reset the gpu.
