If you can get there, go to control panel, system, advanced system settings, advanced tab, settings butotn under start and recovery, and uncheck "automatic restart"

Then check your disk for errors.
Open Computer by clicking the Start button Picture of the Start button, and then clicking Computer.
Right-click the hard disk drive that you want to check, and then click Properties.
Click the Tools tab, and then, under Error-checking, click Check Now. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will simply report problems but not fix them.
