I purchased a laptop used from ebay and I keep getting the BSOD intermittently. The computer runs for a while but without notice or regularity will just crash to the BSOD. I downloaded BlueScreen View and the crash has the code 0x000000fe. Also every few minutes the notification bar will pop up with usb device not recognized error. The bug check string is bugcode_usb_driver if that helps. Anyone know how to solve this problem?
