Worst Computer Accident (Score 1)

My worst computer accident took only seconds to cause and hours to fix. I upgraded my BIOS with a similarly numbered BIOS version, but the incorrect version. After spending a few hours worrying about what I was going to do (buy a new motherboard, etc.) I ran across a forum posting that suggested I might be able to boot up with a good BIOS, hot swap the bad BIOS chip with the good one, and burn the correct BIOS onto the bad chip. It seemed like it had a chance to work, and sure enough it did.
