on stating my sony vaio laptop running on a windows xp home edition, i get the vaio display then the windows xp screen also comes on and thats where the problem begins. i no longer get the meter like thing that increases on the bottom of the page,the screen just stays black for a while then shows a blue screen and hangs permanently.Using the F8 botton brings up the required page but the up and down buttons dont respond so i cant select last good configuration.Occasionally however when i power on and off repeatedly it does come on going straight from the wndows xp screen skipping the meter thing and goin straight to the log on page. After entering my password and booting it displays a new hardwar installed message saying ‘ACPI UNIPROCESSOR P.C’ installed and asks me to reboot which if i do i may end up not being able to boot again for a long time except i’m lucky. PLEASE HELP.
