one of my friends built this comp about a year and a half ago, i dont know all the specs but here is what i know asus p4p800 se nvidea 6600gt, p4 2.4, 1 gig pc3200 with heatsink. before this problem the computer wouldnt work at all it would just start up and just give a black screen with a flashing underscore.... so we got a new hard drive and put it in and installed windows and now this is happening.
