OS Boots Then Restarts?

[carpenma]

Ok so I just fixed a computer and reinstalled the Operating System. I booted it once an installed all the drivers again then restart it. Upon doing so it failed to boot the operating system. I rebooted it again and said start Windows in safe mode. This results in the Windows XP loading screen appearing but when it goes away the whole system restarts. The same thing happens no matter what I select on the "Windows did not start up last time" screen. Help please? Thank you

If you are using a SATA drive, change the controller to AHCI mode in the BIOS.
