I have geforce mx400 64mb installed. bios shows that my geforce is 64mb but when i click dxdiag it shows that my vga is s3 savage 2000 with 32mb. how to solve the problem/

in Acer Aspire Series is using Intergrated Graphic Card.
that mean if you wanna Upgrade your Graphic Resolution,
you have to set to a bigger shared memory/RAM for Display Graphic Card/VGA memory from BIOS Setup.
for example if you using RAM 2Gb, and you can make your VGA(Video Graphic Adapter) to 1Gb.
But in My Computer Properties the RAM will Show only 1Gb.
Because another 1Gb of RAM you've use for VGA.
you can check it from dxdiag.
(for opening dxdiag > Click Start > click RUN... > type dxdiag > and Oke/Enter)

the drivers might not be installed correctly you might have to uninstall the graphics card restart your computer then reinstall the graphics card and its drivers

If your computer came with a motherboard disc the drivers could be on it

Click start control panel administrive tools computer management device manager scroll to display adapters + to expand you might see a yellow question mark ? or exclamation mark ! or a red x right click select reinstall drivers or you might need to download one

Possible Reasons & Fixes:

* Review your Direct X services:

1. Click Start, then click Run.
2. In the Open box, type dxdiag, then click OK. 3. This will run the DirectX diagnosis tool.

Failing that check whether there may be a conflict with any of your devices by clicking on your control panel and checking for any exclamation marks against devices.

* Try upgrading the RAM, which is likely to be the cause for issue if everything shows normal in Dxdiag settings. [Note: High graphics games is likely to lead to overheating GPU]

did the card come with any software.
once you install the card in the system and startup pc the new hardware wizard should automatically pick up driver,
before you install write down exactly what type of driver and model
and if the wizard does'nt pick it up you can install yourself through add nnew hardware

Did you have an ATI card previous to the Nvidia card you are now using. It could still be showing in your Hardware device manager as the primary device (or onboard graphics). If so,delete it and reinstall the Nvidia card and all should be well.
