I'm stuck on this one. Everytime I try to hibernate or even shutdown my computer it gets to the blank screen and then just hangs. I'm forced to shutdown by the power button which I don't like to do. When I put my computer to sleep and wake it I get the Blue Screen of Death and it says "SYSTEM_SERVICE_EXCEPTION". I've tried disabling and re enabling hibernation to no avail. I'm wondering if my video drivers could be the culprit. Please assist. I'm running an eMachines E525 laptop with Windows 7 Ultimate 64 bit.
