What were U doing before this happened?
Any errors recently?

A few things to try:

Reset bios to default;
Disable automatic restart
Boot from win cd, and go to recovery console. (in bios set cd to boot, press R, type 1 , type pass if you have any, if not leave blank and press enter)

do a chkdsk , fixboot, etc

First a chkdsk /f or U can choose by typing chkdsk /? for more options

If that don't help U can try to replace 4 system files from Windows\Repair folder to System 32\Config but you need step by step info because its risky.And if U don't want to do that then the last resort is a repair install.
