Ok, I cleared the BIOS, and now that part seems to be ok. However, I'm getting some other problems now. Explorer is being seriously temperamental, and not just crashing but locking the whole system up for no obvious reason...
How worried should I be ?
Its now about the 5th time through this sequence:
Boot into windows
Open up my computer
Within a handful of clicks, a full system lock up... Can't Ctrl + Alt + Del or anything. Mouse still moves, but thats all. I can't interact with anything.
