do you have an agp video card installed? I would pull the agp card and use the onboard video from the mobo if it has one. If not, you probably have fried the video card as well. However, if you are using window xp and you installed a whole bunch of new stuff...mobo, cpu etc. you will need to reinstall windows xp. Ususally, with alot of new hardware, you get a blue screen without a windows reinstall!
