I just installed video editing software and it tells me that;
"An error has occured trying to use your graphics card. Please be sure that your graphics card supports the minimum requirements and the latest graphics drivers are installed."
It requires a DirectX 9 or 10 compatible graphics card with 64 MB, 128 MB required for Plug-ins.
How can I find out what kind of graphics/video card I have and how can I upgrade it.
Here are two free utilities that may answer all your question

Belarc Advisor from http://www.belarc.com
If you were post to the Model number of your PC that would also help.
