I just installed Windows 7 Ultimate, and installed various drivers, but I can not classify my computer with Windows Experince Index. When I PRESS: Classify this computer, writes:

"Windows experince index of the system could not be calculated.
The assessment, requested can not be completed. This computer does not have the necessary multimedia support to run the assessment which was requested "

Is there any driver kerfuffle that come into play? I have installed chipset and graphics drivers!

It was no problem when i had Vista installed.

Other stuff?

My computer: Acer Aspire 5738ZG

Intel Pentium T4200 (2.0 GHz, 800Mhz FSB)

Nvidia GeForce G105M - 512MB

500GB HDD (5200 RPM - I think)

My WINSAT log says:
