Yes, I'm here. What I meant by fill out your system specs was click the 'User CP' link at the top of any SevenForums page, then on the left hand side click 'Edit System Spec'. You've done some of it already but please fill out the rest, especially your graphics card, which can be found like this: go to Start menu -> search "System Information" and click first result -> expand "Components" and click "Display"
From what you've told me so far, I can say it might be an issue with your processor - you're running an Intel Celeron, where the minimum CPU requirement for KotOR 2 is a Pentium III or Athlon. But hopefully that's not a problem - we'll figure it out.
