Randomly when i'm playing video games my pc will just shut itself down and immediately reboot. It will treat it as an improper shutdown and ask for normal or safe restart. I have verified that my gfx cards are sli'ed together. They also have the newest drivers available. Any ideas?
*Try running 1 card only (try each one in each slot)
*Try running with no GPU at all, use the IGP of the 2600.
*Try each ram stick in each slot individually.
*Make sure everything is updated.
Off topic: why did you buy that PSU???? you could have gotten dual GTX580s and a nice 850w PSU instead of that, and unless you're doing heavy video editing/decoding/encoding/transcoding/running VM/use fraps with high details there is no need for an i7.
