Gforce2 runs jerky on Directx8 . I want to re-install Directx7. I found a uninstall program at zdnet. It tells you to back up your "syst user.dat" in C:\Windows directory. When I did a search files , I got back 31 folders with "syst user.dat" . Do I creat a file to back them ALL up? Also wants me to copy C:\Windows\sysbckup folder elsewhere on harddrive. How do I locate & backup? Kind of a newbie to this stuff, would appreciate some direction . Thanks , Rich
