Hardware acceleration is either disabled or not supported by your video card driver

[julius]

When I open window 7 games it shows the message "hardware acceleration is either disabled or not supported by your video card driver,which could slow game performance.make sure you have the latest video card driver installed and that hardware acceleration is turned on."
in my device manager under sound,video and game controllers it shows unsupported standard game port. Resolution is also changed.

When I scan for hardware. One unknown driver is present in Device manager what to do for resolving this issue? please help me to fix this problem. My laptop is Acer Aspire E1 -431

Try installing the default OEM graphics driver. If your system has Intel graphics, use this link to download the driver. If it uses nVidia, use this link here. If you don't know which one it has, start with the Intel.

You can also see all available drivers for your laptop at this website. Select Notebook -> Aspire -> Aspire E1-431. Select your Windows version from the drop-down menu. The graphics drivers are called VGA.

You may also use SlimDrivers Free to detect missing or upgradable drivers, although I wouldn't use it to replace drivers for devices with which there is currently no problem.

Good luck on your endeavour.
