my computer restarts by itself. it's been doing it a lot more lately (about 2 or 3 times a day) i've reformatted twice since it started and have still gotten nowhere. when i send microsoft the error report, it tell me its a "error caused by a device driver." but it tell me the device is unknown. i updated the drivers for every device in my device manager many times, but nothing works. i'm assuming that there's some problem that my computer has with the driver of some piece of hardware i have installed, but i have no way of telling what that piece of hardware is. if i could find out what it is, i'd ripping it out and replacing it. this is drving me nuts. our IT guy can't figure it out, but that's not surprising because he's an idiot. any help would be greatly appreciated.
