Go to Start - Programs - Accessories - System Tools - System Restore. Open it and select a restore date prior to the time you installed DX9. Your system will be restored to that setting.Bill

Running a GeForce 4 Ti 128mb blah blah blah and installed the new drivers plus DX 9. Looked fine for awhile then I started to get these yellow and blue lines on by screen and sometimes would crash. I am gald I created a restore point before I installed everything. All seems fine now. Other than a heating issue with my machine, but that is easy to fix. Right now I have the case off and a fan blowing into it... Should go out and get some fans.... to install....

Running DX9.0 on an Athlon 2000+ and Radeon 9700. One word. Awesome!!!I lock my frames to 25 and that is where they stay with only occasional drops below that. Smooth as silk running 1600x1200x32 4X AA

Thanks for you're replies.. i'm giving up on gaming, screw it.. never works right for me.
