REPLY TO MY PROBLEM:
Did you update any drivers lately? Open the Start menu and right click
Computer in the middle on the right. Choose Manage from the pop-up context
menu and click Continue on the UAC prompt you will receive. Once Computer
Management opens, click Device Manager in the tree on the left. On the
right you will see a tree of the devices connected to your computer. I
would start by expanding the display adapter node. Right click on the icon
for your display adapter and choose Properties. In the «Display Adapter»
Properties dialog box click the Driver tab at the top. If the Roll Back
Driver is not grayed out, click it and let Windows roll back the driver.
Then reboot computer.
If that doesn't get it, or it was grayed out, try some other devices.

I tried the suggestion above. It did not work. Is there anything else I can do?
