is there any other way except reinstallin OS again.
My os is win 7 ultimate..

That sounds like the side effect of a virus.
Do you get the same behavior in safe mode?

Ye s

Hello snpshare, welcome to Seven Forums!


If the sfc /scan doesn't work, be sure to run it a couple times to be sure, as it sometime takes a couple runs to complete successfully; here's another method to use, it may be better because the system won't be 'in use' during the scan.

SFC /SCANNOW : Run in Command Prompt at Boot


If none of that helps, have a go at a repair install; see the tutorial at the link below and be sure to post back with any further questions you may have and to keep us informed.
