computer freeze up...
My computer is freezing up randomly. its an HP with windows 7 64 bit, I only use it for editing photos, its rarely on, and it has never been connected to the net. after i power off with the power/reset button it turns on but the mouse, keyboard, and monitor do not respond. if I unplug power and let it sit for a while I can reboot to safe mode, if i try to reboot right away the PC powers up but the keyboard, mouse, and monitor wont respond. I have no idea what could be going on, any advice?
