Hi,
Could do with some specs on your system.
Ahhh....I see now....you need to go into
safe mode, try my earlier suggestion:
Safe Mode
Reboot your computer, At the splash screen press F8, keep it pressed down or reapeatedly tap, this should take you to Advanced Boot options. It may not work first time, catching it right is sometimes tricky.
Try Repair my computer option first. If that fails:
Do same F8 procedure and boot into Safe-Mode then follow my previous steps for System restore and SFC /Scannow
cheers
