PC randomly reboots when something new is loaded in games.

Ok, for a while now I've had an issue with my PC. When playing games it will randomly reboot, it's not an overheating issue, there are no irregular voltages, there are no signs it's about to happen it just does.
Oddly though it only ever happens when loading something new in a game e.g. a cut scene or joining an online game etc...

My PC specs are
i5 2500k @ 3.8GHz with a Corsair H60
Gigabyte Windforce 2GB GTX 660
500w Mushkin PSU
8GB Radioactive Mushkin Ram 1600Mhz
120GB OCZ Agilty 3 (OS disk)
1TB Seagate Barracuda green
Gigabyte z68ma-d3h-b3

However even more oddly under stress testing - Prime95, Memtest, tests on OCCT my system remains completely stable and passes the tests with max CPU temps of 65°c and absolutely nothing out of the ordinary.

I would have suspected my SSD/HDD but it does it no matter which drive the game is running off.

So I'm guessing my GPU is probably at fault but it just seems so odd I had to ask.

There are no error messages what so ever before it turns off, even in the event viewer it just has error 41 for power loss.

Ok thanks, but why would the problem only occur whilst loading new things in games? Plus I ran the OCCT stress test on the PSU and GPU but I understand it probably isn't the best test. Could you recommend a test so I can be sure?
Thanks

Ok, I have done that. Experienced no problems, max GPU temp of 74 degrees. However I modified my overclocking, changed a lot of stuff off auto and turned off turbo mode too and so far so good. But I haven't had enough time to be sure yet. I'll update if there are any further issues.

Forgot to add I ran Intel Burn test too and had very safe temps and my system remained very stable.
