Why is my computer restarting and then changing the boot priority of my hard disk drives?
Two times now, I've returned to my office to see my computer sitting at the boot screen telling me that I've inserted an invalid system disk (or that nvldr is missing if there's no disk in the drive). Last time this happened I eventually figured out that the bios had somehow changed the boot order of my hard drives and switching them back solved the problem. Only for it to happen again. It's only happening when I'm not using the PC (downloads and email still running). I've got an AMD 3200+ withd 2gb of ram (DDR400) and an Asus 6600GT. I've just added 1gb of ram, but I matched the manufacturer, speed, size and everything else, and it seems unlikely to be causing the problem. Any thoughts?
