If you already downloaded the latest graphics drivers off Intel web site 22.214.171.12475, make sure your computer is not a switchable graphics computer; this means your system may have Nvidia or ATI card to work in conjunction with the Intel graphics.
If your system is switchable, Intel drivers won't work for your machine and you will need to contact your computer manufacturer to get customized drivers for your computer model.
