First thing to do is make sure you are running the latest drivers for your graphics cards.
Nvidia's graphic drivers can be found here.

Be sure to check the name of your card. For example a Geforce 8800GTX uses different drivers from a GeforceMX440.
With Nvidia, you can install the latest drivers over the old ones. A reboot may be required after install.
Ati drivers can be found here.

First select your operating system, then you card, (a standard radeon card or a mobility card found in laptops) then the model number/name of your card. This will then pick the latest driver available for you card.
With Ati, after you have downloaded the new driver you will need to uninstall the old driver. This can be done by going into add/remove programs and selecting Ati - Software Uninstall. It will be near the top. After you have uninstalled, reboot. Then after a reboot, proceed to install the drivers, after install reboot again and your good to go.
