In case the problems remain with you changing the video driver versions, there are other steps you can follow.
•Step 1: Check if the power supply in your PC is causing problems; the video cards that support multiple displays use a lot of electricity. Avoid getting a video card that needs its own separate power connector and must be considered much of a drain on the power supply.
•Step 2: Also find out if the card is defective. If you replace your present video card with another card, it might not work. Swapping your video card with a card that does not use an external power connector rules out the power supply draining problems.
•Step 3: A failing motherboard can also be the source to all video driver problems. You may try fixing this motherboard problem, only when the other two steps have been explored to no avail.
If problems persist and the above mentioned steps have not been able to help you, you may try contacting a remote computer repair company for tech support.
