I tried installing Windows XP Pro on my pc,its a Core 2 Quad 2.33Ghz,500gig hard drive...My XP disc did not have service pack on it,so every time i tried installing the OS it would create 3 partitions of approx 160gig on the hard drive...it never got around to fully installing the OS it usually rebooted and started re-installing,any ideas on what the problem could be???
