You can try to boot Last Good Known Configuration by pressing F8 key as soon as Power on Self Test finishes and windows is about to boot.

If that doesn't work, you can try to boot in safe mode by pressing F8 key as soon as Power on Self Test finishes and windows is about to boot; if your system can boot into safe mode, trying restoring it some earlier restore point. Regards
