i just opened it up and cleaned all the fans and such last week so i dont think its that. its running 32 bit XP pro with an abit KN9 SLI motherboard, 2GB corsair DDR RAM, GeForce 7600GS card. Its been happening for a while on and off, for a while it would go as long as a week without any signs but lately within 5 minutes of turning it on it freezes, not as many random restarts as before. havent seen any BSOD's in a while. there seems to be no link to when it happens as far as what is running and ya i do have a surge protector on it. The link for WinDbg on the second link seemed promising but it brought up nothing does anyone have another link to the same program? ill make all the changes to the BIOS and work on the UBCD and repost later. thanks for all the help everybody.
