I have the former Nvidia 6600 and am running 188.8.131.5244 or 163.44.
Install that, then run dxsetup and retest.
One of my PC starts giving trouble, recently the PC couldnt boot Windows so I used the WinXP CD to repair the Windows, and it did work, up until now I did not play or load any games/programs that required 3D application. Please look at the screenshot:
So any idea how to fix? I've already downloaded and installed the latest driver from nVidia (175.19), still the graphic is still like that. And also I've tried most of the settings in control panel, still the problem persists. I cannot play games with graphic like this...
This PC specs:
Windows XP SP3
Pentium 4 2.4Ghz
GeForce 6600 (using latest driver 175.19)
