Open your G2 control panel and click on the Tech support icon. This will bring up a new menu and will show all of your sytem staus. In the upper right hand corner, there is box marked DX with 4 options beneath it "Billboard, CHATPEER, Sound, and Joystick." Click on these individually and it will run a short "test program" of each one and may identify which part of the system is causing you problems. From there, I'd say you will probably have to relaod your drivers. I tried the uninstall/ reinstall program options several times and it only fixed my problems temporarily. Finally, I reloaded Direct x, updated to the newest version of G2 from the website, had to reload my video/ sound/gaming options drivers and crossed my fingers. After a reboot, everything seemed to work (and has been working for me for about two weeks now). Maybe this will solve your problem, or at least help. Good Luck! Rich
