I found this:
VIA/S3G UniChrome Pro IGP - CNET Download.com
The application might not run on Win7. but there is another method:
1-Unzip the files.
2-goto: START>CONTROL PANEL> type "device manager" in the searchbox.
3-run DEVICE MANAGER> find your graphic controller> right click on it> PROPERTIES> select "update driver" (or similar)> select "browse......" instead of "automatic...."> open the folder what you unzipped (in the utility)> and complete the installation.
If it wont help, and there is no "!" symbol near your graphic controller in device manager, than lets assume its installed properly.
If you still think it isnt, let us know the reason why.
note: the content doesnt contain compatibility information, but it wont couse any problem.
