I bought a New Computer in 2002, From CompUSA. I Gave my Dad some 2000 In cash, and in turn he paid for it using his Credit Card.
I put a CompUSA Warranty on it, and Also bought a Internal 100Mb Zip Drive.
They told me, They would have to put it (Zip Drive) in themselves, or I would void my Warranty, So I agreed.
When I first took my Computer home the Next day, It didnt work.
So I boxed it back up, called a Cab and drove out to Comp USA to have them fix it. They gave me an odd look, And I told them what I thought was Wrong. I told them I think its something to do with my Graphics Card. They Disagreed, and thought I downloaded a Virus. I told them, "Look, I turned it on. And it didnt work. How could I have D/L a virus?"
I returned to pick it up (Three Days Later), and they told me it was Graphics problem afterall

Flash to the Future-
My Computer is dirty, I can plainly see it collecting dust on the vents and such, So I decide to open it up an clean it. I unscrew all the fans, to give them a good cleaning. While I'm unscrewing my intake fan I notice that One Screw appears to be in a different posistion than all the others. I unscrew it and take a good gander at it.
The Idiots at CompUSA screwed the screw into the wrong hole and cracked the corner off my fan. It still works, but just goes to show If you work at a overpriced Computer "Superstore", doesnt mean you can operate a computer.
Next Computer I get, I'm building it myself.
