That reads like a direct 3d error. Try reinstallin directx.

If this still fails....I would be try to update all the drivers....If this still fails I would contact the fellow I left it with. Sounds like they purged some info. When you say "Next morning my system wont boot up. I took it in and got it fixed" Would it post? make that beep it makes when you turn it on?

Maybe it upgraded something your PC couldnt handle.... like directx 9. Just a thought. I hope I helped ya out.
