Parameter 1-Parameter 2-Parameter -Parameter 4-Cause of Error
0x5-----------Reserved----Reserved-----Reserved---A hardware failure has occurred due to a bad physical address found in a hardware data structure. This is not due to a driver bug.
If you're running your webcam using USB, I'd suggest trying another USB port (not the one next to it). If it still BSOD's on you, I'd have to suspect either the USB device, or a problem with the USB stuff on the motherboard.
