I recently disected my gateway select 800 for de-dusting purposes and now that I've re-assembled the tower, the lights on my cd and floppy drives stay on and the drives won't work. The computer won't recognize any disks I put in, but all else if fine as I'm using the pc right now. Could this be a wiring error? I was careful not to damage motherboard components and such. Thanks in advance for any advice you can give.
