First, check your BIOS settings for your IDE drives. If you don't have "compatibility" mode selected, many HD commands get "lost," and the drive is selected a lot. (At least, that's what was happening on my system after a BIOS upgrade changed the default to "enhanced." It also "killed" my printer by defaulting it to unselected instead of the parallel port. Easy to change, but it took me a while to figure it out.)
Second, when's the last time you cleaned your CPU cooling system? Dust on the heat-sink radiators can cause overheating. But I suspect that the HD problem may be causing a CPU loop waiting for an interrupt response.
