Hi Prashant,
What are the recent changes that you have made to the computer prior to this issue?
This seems like there are some corruption in the operating system. This might also happen, if there are some serious conflicts in the computer. I would suggest you
to try the following methods and check if that resolves the issue.
Method 1: Perform a Clean Boot and find out which application/service is causing this issue.
A clean boot helps to eliminate software conflicts and to determine what is causing the problem. Perform a clean boot on the computer by following the steps given
in the link:
***http://support.microsoft.com/kb/929135***
Follow all the steps given in this link and try to figure out the application or service causing this issue. Please note that performing a clean boot does not fix
the original issue. It just helps us in understanding the cause of the issue.
Note: After you have finished troubleshooting, refer to the article “How to reset the computer to start as usual after clean boot troubleshooting” for Windows 8, given under the section “More Information” to reset the computer to start as usual from the above link.
If the issue persists, then you may have to perform a refresh of the computer
Method 2: Refresh the Computer
To perform a refresh, you may refer to this link:
***http://windows.microsoft.com/en-us/windows-8/restore-refresh-reset-pc***
***Important:***The apps that came with your PC or you installed from Windows Store will be reinstalled, but any apps you installed from other websites and DVDs will be removed. Windows puts a list of the removed apps on your desktop after refreshing your PC.
Hope this helps.
