Computer dumb.

KCAL did an undercover camera investigation to which computer repair places were incompetent/scammers. They took perfectly working computers and just disconnected the cable from the hard drive to the motherboard, then took the computers to different repair shops to see what they said.

The results were varied and shocking:

Best Buy: Said needed a new power supply
Circuit City: $59.99 "The jumper was set wrong"
COMPUsa: Charged $119.99, their minimum charge, but correctly diagnosed and fixed the problem
Fry's: $69.99, fixed all good
Torrence Computer Repair (local): Fixed, at no charge b/c it was so easy
BM (local)I: $275 due to "power short," as the "main board" and "hard drive" were "bad"
