Whenever I turn on my pc, like every other system running windows XP, i get the familiar loading screen with the little bar going across. However, 1 time out of 2 it stays loading at this screen for 10 minutes or even more. I have a limited amount of startup processes. No full folders on the desktop. Spec: AMD Athlon64 4200+ 1GB DDR Ram Antec Smartpower2 500w PSU 160gb Maxtor Diamondmax S-ata Hard Drive Nvidia 7900gtx 512mb PCI-e Any ideas anyone??
