You need to install drivers for your video card. You will not find them at Windows Update or on your computer.
Get them from:
- The device mftr.'s website; OR
- The motherboard mftr.'s website if hardware is onboard; OR
- The OEM's website for your specific machine if you have an OEM computer (HP, Dell, Sony, etc.).
Read the installation instructions on the website where you get the drivers.
To find out what hardware is in your computer:
- Read any documentation you got when you bought the computer.
- If the computer is OEM, go to the OEM's website for your specific model machine and look at the specs (you'll be there to get the drivers anyway)
- Download, install and run a free system inventory program like Belarc Advisor or System Information for Windows.
