Does anyone know when i play a file avi file in media player 8, i get the blue screen of death. Some times it reboots by itself, but mostly in media player 8. Then when i restart one of my harddrives doesnt show in the BIOS. I have open the box, unplug the HD and plug it back up to see it in the BIOS? Could this be a issue with the bios or the power supply?
