Ok, I'm back. Start to install all my stuff and every time I install a new program. I run the DirectX test and I got it. After I install my Intel Pocket PC Camera, I got this in the test.

The file iac25_32.ax is a beta version, which is unsupported and could cause problems. You should reinstall DirectX to get the latest version.

The file nvdisp.drv is uncertified, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs. You may be able to get a certified driver from the manufacturer of the hardware device.

I reinstall DirectX and I got the update from nVIDIA for my grafik, but same result.
What do I try now ??
