But kind of a friendly one.

Computer clanked off in the middle of the night on it's own.
Wouldn't turn on in the morning.
Looks like a job for Geek Squad.
Geek Squad replaced power supply.
Computer then worked when picked up and taken home the next day.
Unfortunately, the monitor did not -- as the place where monitor plug is to be connected -- is now somewhere within the confines of the computer tower.
Looks like a job for owner of computer.
Computer taken apart by owner.
And put back together.
Computer now sounds like a helicopter.
