Recently, we had this San Jose service check our pc and were told that in turning off all the switches ,before, the computer had completed its sooo slooow Microsoft shutdown process,,,we had damaged the hard drive and would need to buy another one. We are non-tech professionals, teachers and such, so we did. Then i talked to 2 software engineers with ee degrees and several computer stores, like CompUSA and CircuitCity, and they all said that was impossible. There is sooo much demand for techs to fix pcs that i do not understand the need to pad a bill,,, or overcharge,,, or charge $220 just to come to your house and drop in / load a disc by Geek Squad,,,or charge $30 to show up at your house and $50 per hour,,,when there is sooo much work out there at just a more fair $30-50/hr.
