Go to your Start Menu.
Go to run.
Type dxdiag.
Click ok.
At "System", you will see your processor name and stats.
At "Display", you will see the name of your video card with its stats.
I suggest you find another firewall then the one included with Service Pack 2. Turn it off and get either
Sygate (

or Zonealarm (

You can simply turn off the Windows Firewall.
I think that your problem is video card related. Perhaps you should consider reinstalling Kotor along with all the latest drivers.
