A lot of times the driver will be for Vista but work with Windows 7 as well. It is also possible you are using an old driver. I would try updating your Intel video drivers. Go to your PC/Laptop manufacturer's website (if home built PC, the motherboard manufacturer's page) and download the latest version of the Intel graphics drivers. You can also find them from Intel's page at http://downloadcenter.intel.com/default.aspx,
but it's always better to try to get the driver from your motherboard/computer vendor in case their board uses custom OEM settings.
