if the blue screen continues then remember to look at the cables as well as the larger pieces of hardware. when i first got my pc the company sent me 3 gfx cards, 3 HDD's and RAM sticks over a period of 2 months. with over 10 windows re-installs too. turns out it was one of the connectors at the end of the cable connecting the HDD to the Motherboard. all that hassle for 1 little cable.
