Are you having problems with Facebook games on Facebook using IE9 or Firefox 4? Another solution…
So I figured something out recently, if you need the hardware acceleration turned on (I have to admit it is a nice thing to have) in your web browser, the problem might be related to your graphics driver. Most laptops today use the Intel graphics drivers. Go to http://downloadcenter.intel.com/ to download the latest drivers (Microsoft’s Windows Update is a little behind on this) then follow the on-screen installation steps. If you are unsure which drivers you have on your system they have a utility that can help you, simply go to http://www.intel.com/p/en_US/support/detect.
If this is not the case for you I recommend going to my previous post, which is still very useful if you are not using an Intel chipset.
