Hi,

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 PC (Sony Vaio VGN - NW240F/S)
