First, determine what specific make and model video adapter you have.
The most obvious places to look would be the computer's manual, inside
the computer's case, getting the information directly off the adapter,
or on the computer manufacturer's web site. Failing that:
1) Start > Run > MSinfo32.exe.
2) Start > All Programs > Accessories > System Tools > System Information.
3) Start > Run > DXDiag.exe.
4) Right-click My Computer > Manage > Device Manager.
5) If none of the built-in tools provide the information you want, you
can use these utilities to help determine the answer to your question:
Unlimited Possibilities' AIDA32
Lavalys' Everest Home
Next, consult the manufacturer of your video controller, usually via
the manufacturer's support web site, to see if there are any newer
drivers for your specific video adapter. If there are, follow the
manufacturer's instructions for downloading and installing said new drivers.
