Switch On your PC/ Laptop and log in to windows.

Go to 'Start'--->Programs--->Accessories--->System Tools--->Click 'System Restore'

A 'System Restore' window will appear.

Here you will have to check "Restore computer to an earlier time' and click Next

Now you will find one Month Calendar window with Dates below, go to the previous month by clicking the '<' sign in the upper left hand corner of the Month Calendar and select any date that you see in Bold.

Note: It is better if you could remember from which date you are facing the issue, try to select a date prior to that date.

The detail of that particular date should show "System Checkpoint" and time on the right hand side box. Select that date.

Now, Click on Next and System Restore will start and windows will take a reboot.

After reboot your problem should be resolved.
