Otherwise, just for a check, Open an elevated command prompt (start > all programs> accessories > command prompt, right click it and run as admin), type sfc /scannow and hit enter. Wait for the scan to be completed, and restart. If the issue is due to any system file corruption, that will be fixed by it.
