ok i have had this set up for 1.5 yrs now and it runs pretty well. i hope the parts list is in my sig if not will reply with rig parts list. Pc post gets almost to windows where blue bar scrolls across screen at xp screen. scrolls twice the pc keeps rebooting. i tried installing win xp on a new hd does same thing. took out all non essential parts. just barebones. hd,cpu,dvd drive,psu, gpu. all fans are connected n spinning . took off heatsink cleaned n reapplied thermal paste. blew all dust out of case. tried one stick of ram switched mem slots. dunno if its psu? dont think gpu would cause it. dont have have a rig to try psu in or try ram in. ok with main hd in pc just gets to win xp screen n reboots. i tried installing win xp on a external usb wd my hd but then i get lue screen of death.
