I have this problem where, out of the blue the screens change to a multicolored layout, and if there's sound it locks and stutters and the PC reboots shortly there after.
This can happen right after a fresh install of W7 X64. It can also happen as soon as I reach desktop. Or if it boots cleanly to desktop it can happen right after launching first game. And sometimes the comp doesn't reboot it self afterward.
It started happening after I tried last Nvidia WHQL drivers, and after that regardless of drivers or installs it ends up happening.
Is the Matrox box faulty or is my GPU dying?

EDIT: Just tried without the matrox box, still happens. Guess GPU is dying. Anyone know why it would do this though?
