White screen after playing Q3 arena

I got problem on exit to windows after playing Q3 arena. The screen will become really bright. It just can solve by restart the PC. I got 3PCs installed with:

Nvidia GeForce2 MX200/400
Nvidia driver ver2109
DirectX 9.0a
Win2K SP2

I suspect this is the problem of DirectX coz Q3 arena originally play with DirectX 7.0 & i got no problem at that time. but since i need to play other games which required more latest ver of DirectX. I have tried to installed the latest point release 1.32 of Q3 but the problem remain the same.
Pls help me,thankā€¦
