A while ago (back in the DOS days) my neighbor at the front Ranch was complaining to me that he was having computer problems. He asked me to take a look at his PC for him.
Tried booting up the computer, only to be rewarded with a series of beeps instead.
I pulled the outer case off the PC, and noticed inside that a mouse or some mice had made a nice cozy nest on top of the CPU composed of hair, foam, and carpet fuzz.
The rodent, or rodents had also chewed some up some wires and insulation. The biggest surprise though was the IDE ribbon cable that connected the Hard Drive to the PC Mother Board had been chewed completely through.
Since I'd assembled that PC for my neighbor out of parts, I had cables and other pieces on hand. I put it all back together with a new IDE ribbon cable, and everything worked fine after wards.
The diagnosis was easy. I told him the problem is you have mice.
Bet folks who do tech support don't get to say that one very much, but it probably happens more often than you'd expect.
Gives a whole new meaning to the term "computer mouse".
