PC keeps shutting down when playing games(sometimes)

[JeremeyTheFox]

okay so i made a post awhile back about this same problem which stopped for awhile until today
Started playing wow again and well computer shuts down after about 10-30 mins game time
My Build
http://www.ebuyer.com/lists/list/247759
With xtreem team 8GB 1600mhz ram (4x2)
(Coolermaster K350 Case and Elite 500W PSU Bundle. Since they are out of stock its not on the list)

Its been quiet for awhile only started playing up again
All temps are fine normally all below 70C while playing games at 1920x1080
and an idle second monitor for browsing the internet and skype etc
upped the fan speed thought it might be a heating issue which doesn't seem to stop the shut down.

GPU usage normally goes to 100% then the shut down is not long after when i have msi after burner up.

Any help at all will be greatly appreciated

It looks like the GPU is the culprit. But tell what is the issue. It could be something a simple as a driver issue, it could be power, or the card could be failing. Hard to say exactly.

ive tried updating the drivers and reinstalling with no joy, could this problem be mobo related?
also while on mobo related, after updating my mobo was a suggestion to fix the shutdowns i now cant get access to my bios at all crashes upon trying to load, i think my system is dying and is less then 2 month old.

those 2 cpu/gpu can really drain power so om guessing its your psu what is failing cuz it not the best quality only 500w and its shuts down when it is useing most power in gaming

Do you have psu to suggest? I need one that will be mounted at the bottom so I need pretty long cables to power the mobo. As I would prefer not to buy extenders

You can get quality PSUs (I would suggest 550-650watts) from Seasonic, XFX, Corsair, and Antec.
