If you are not getting a black screen, I suggest that you restore your system to a date back before the problem occurred. You will not lose any data.
Log on to your computer as an administrator.
Open the Control Panel by clicking Start, and then clicking Control Panel.
Click System and Security, and then click System.
Under the Control Panel Home menu, click System protection.
Click System Restore.
Recommended Restore is the default choice. This restore is the most recent restore point and the best place to start.
To choose a different restore point, click Choose a different restore point, click Next and then click a restore point.
Click Next, and then click Finish to confirm your restore point.
To start the restore process, click Yes.
Once the system restore is complete, your computer will restart.
