The computer keeps shutting down, then automatically starting up every time I load a game.
What's the problem? I've logged temperatures, done stress tests, nothing seems to be the problem. My processor hasn't even been touched in terms of Overclocking it yet. The video card came OC'd out of the box.
I'm using Windows 7 x64.
There are no games that work. Assassin's Creed, Left 4 Dead 2, all of them turn off as soon as the game loads. Even Warcraft III.
I have the latest GPU drivers. I forgot to mention that I have the latest drivers, including BIOS revision, as well as I tried memtest86+ already.
This is the first system I have built where I have come across a problem such as this.
When you updated BIOS the last time, did you load the default settings? Did you change anything?
Load a game to make your system crash. Reboot and enter windows. Check your Event Log - by opening the Event Viewer application - and look for any errors or warnings that occured at the time of the crash.
