Hi folks, new to the board. This is my first build and I'm having an issue. I have a ASUS P5Q SE/R MOBO, INTEL P4, RADEON DDR RAM, WESTGATE 300GB DRIVE. RUNNING WINDOWS XP. It' s just a basic set up. System was running fine for a few days but now it boots up to windows load screen for a couple of seconds and then reboots itself. I have to shut PC down to stop it. I tried removing all devices but nothing works. I can;t get it to log into windows. Not sure if it's hardware or software related. Any advise on what to try next??? Thanks.
