changed from PC Channel.? I have updated my Windows Vista 32bit to Windows 7 64bit with very little issues, but whenever I turn off my TV (32'' 1080p Sharp Aquos) or change the channel from the PC without first shutting down, it will blue screen me. I'm not sure if this is a BIOS issue or a driver issue as I have updated all the drivers, and dug around in the BIOS to look for anything that could cause the problem. Anyone have any idea's?
