Graphics card restarting computer

[sapphire_mist]

Hi this is my first post here..

My issue is that my pc shuts down while playing games after 10 - 20 mins. The machine automatically tries to restart but it shut downs again and will not start up till i do a power drain or unhook the main power cable for a a min or so.

My specs are 650 W Cooler master power supply
Ati Radeon Hd 6850
4 gb ram
Asus motherboard


I know this is not an issue with overheating because my system is liquid cooled and the max temp my graphic card hits is around 73

This has been driving me crazy for the past few days. Even took the graphic card to claim warranty but they checked it and said nothing is wrong with it ..Any help would be much appreciated.. Thanks in advance

Power supply or video card are the most likely things here. Try with another video card, or try yours in another system.

The techs connected my graphic card to another machine and confirmed that it works fine.

They checked this when i went in to claim warranty .

THEY checked it. Plug it in, run it for a second, say it's good. Try it with another PC under a benchmark or game for a while.

Finally.. Yes !! Manged to get it fixed. There was a conflict between the onboard graphics and the graphic card. Disabled the onboard graphics through BIOS and it now works like a charm !!
