Pc crashes during gaming

Hi,
I recently bought a new PC, however I am expiriencing constant shut downs without bluescreen when playing games (especially Starcraft II). I tried updating all the drivers, however that didn’t fix the problem.

My specs are:

Operating System: Windows 7 Professional
Mainboard: Asus P8Z68-V
Processor: Intel Core I7 2600k Sandy Bridge
Powersupply: ThermalTake TR2 800w
Graphicscard: Zotac GeForce GTX 560Ti

Thanks in advance

How Much Ram do you have ? Also check for over heating !!!

I have 8gb Ram, and I have a constant 30°C on both the mainboard and the Processor.

8 gigs of ram should be more than enough to push almost any game, And your temp is good.. Next check the Video card, that is where allot of problems come from when gaming…

Well, to my knowledge the GeForce GTX 560 Ti should be able to deal with all games on the current market.

Edit Just now had a new one: When browsing the speaker made a weird “BRRRRRRRRRRRRRR” sound, while the pc was not respanding to any commands given. So I had to restart it.
