Many people have a GMA as their graphic card on their notebooks. There are usually some special drivers shipped with the notebook for the graphic card, which usually work just fine with office programs. But when you start using 3D-acceleration, you might encounter weird graphic bugs. So the normal action an experienced user would take would be updating the driver. But a lot of suppliers don’t allow switching to official Intel drivers, like Dell or mine: Toshiba. When you try to install them, an error message appears and the setup exists. What then? Well, you can either wait for them to release a new driver (which won’t happen usually) or trick the Intel driver into installing. With new drivers, everything might even work worse than before or break your windows, so be sure you really-really need the update.
It worked for me without any problems, but that doesn’t mean it will work for everyone. The reason for that is simple. Intel usually ships new version of their bios with new drivers, which cooperate better. But you shouldn’t install the new bioses because you probably have a modified one from your suppliers specially designed for your chipset. The new bios might kill your chipset making your notebook one expensive brick. So the only thing you can do is to hope that the driver works with the bios preinstalled by your supplier.
To update the driver, you will need to download the zip version of the Intel driver, not the Installer. Unzip the file and open the device manager. Right click on your graphics card and select properties, then update drivers. Now select manual file selection (a few times) and go to the driver directory and choose the driver. The driver should now install perfectly. And if nothing bad happens, you are now using the latest Intel drivers.
