Hi Layback Bear and Roncerr,
Ive carried out the sfc scan twice and rebooted on both occasions,and also done the clean up as advised by Roncerr but to no avail.
Ive even run my Windows 7 disk on the clean up mode,and tried the system repair on that,also gave it a shot in safe mode,but still no joy..
Do you guys have anymore suggestions,i really dont want to do a clean install of my operating system..
