As Derrick says, I dont know what kind of crash would cost you that much moolah? I'm sure it was more a pre-existing hardware crash than anything. But as he says, NEVER take it to a store like Future Shop or Best Buy. Make a geek friend and have them do it. I do it for trade as well. Beer is the most popular, but even a few bucks will have yer system fixed in probably a few minutes.
The PC shops are like car mechanics, they can tell you that your rotary inclosure flux capacitor hose needs to be reverted, and you'll pay for it!
