Never install an earlier version of DirectX than you already have installed, even if it comes on the disk and espically if it is for a different version of windows than you are using.

Do upgrade your system to DX9.0B which you can find on the windows update page.

Also try these things:
1) Rename the AVI folder to AVI_back
2) Set the color depth to 16BIT
3) Turn off everything in the background like E-mail/ICQ/Messenger, Virus protection and everything in the system tray beside the clock
 
Great!
