The problem you are facing is generally caused by some updates of windows.Please follow the steps below to restore Windows to an earlier date, when the problem was not there.
There are two places that you can use the system restore feature from. From within Windows, you can just type restore into the Start menu search box, and you’ll immediately see System Restore at the top of the start menu:
Or you can type rstrui into the search box and hit enter. Your choice.
You will immediate see a screen where you can choose to roll back the system to the last restore point. Select "Choose a different restore point."
If you do choose a different restore point, you will see a list of restore points that you can choose from. How many times have I typed the word choose at this point?
You’ll notice in the screenshot below that the last thing I did was install Virtual CloneDrive to mount ISO images, but right before that I installed the NVIDIA drivers.
Click one of them, and you will have to confirm and then restart your computer to roll the system back.
Click next, and on the next screen select the drive that your copy of Windows 7 or Vista is installed on.
Click Finish, and Windows will roll back to the previous restore point.
