I am giving some steps, please perform the following troubleshooting methods and let me know, how it goes for you instead of rating the answer.

Method 1:

Set the computer to clean boot state and then check if this fixes the issue.

To set the computer in clean boot, follow the steps from the link: How to perform a clean boot

Note: After checking in clean boot, follow step: 7 from the article to reset the computer to normal boot.

Method 2:

Perform System File Check to fix the corrupted system files and then check how it works.

Refer the link "How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7" to perform System File Check.

Note: It may ask for windows DVD to fix and to enable SFC to make more than minor repairs. Some files saved on your computer might get deleted when fixing corrupted files.

Method 3:

Download Microsoft Safety Scanner, then scan your computer for virus and malwares then check how it works.

You can download Microsoft Safety Scanner from the link "Microsoft Safety Scanner".

Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.
