The Tune up utility is probably the problem. Tune up Utility 2012 or programs like it do more damage than good. No one know what such a program does their/there for it difficult to repair what the program has done. Windows 7 does not need a Tune Up program nor does want one. I would recommend removing such a program and go back to a restore point a week or so before it was installed. Then I would do this.
SFC /SCANNOW Command - System File Checker
Hopefully that will fix your problem. Get back and let us know.
