If you have just re-installed Windows XP, did you also install Service pack 2? You will need to post your dxdiag.
Does the game do this during play, or just on start up?

Figured it out... I updated to service pack 2 and installed the AMD K8 drivers, the Dual Core optimizer, and some sort of AMD Dual Core fix for SP2. This started making windows crash every time it started up... that is until i disabled the SSPD service. A post in the kotor tech board helped me figure this out. It seems to have worked for eaw as well.
