Mobile Intel 965 Express Chipset Family Graphic Card(Mobile Intel GMA X3100) Problem in windows 7, Can Bios Updating Be Helpful?

[idata]

Hi,

I have Sony VGN-FZ160E Labtop that its original windows vista detects the video card memory as 128 MB, but when I upgrade(I tried clean installing too) to windows 7, It detects the memory as 64 MB and I get into trouble with graphical softwares(Like Autocad and 3ds Max).

I ask sony but they say couldn't help me.

In windows 7 everything works good except graphic detection.

I want to know that what can I do? Or updating the bios can be helpful? If yes, how can I do that?

I put some images for better informing.
