I would strongly recommend only using the Dell* certified drivers for your system. Dell customizes the Intel HD Graphics drivers specifically for your system and using the generic drivers from Intel Download Center will remove all of the Dell customizations which could impact the performance of your system. You can get the latest Dell certified drivers for your system here: Product Support | Dell US
i have acquired the drivers from the dell product support but it didn't work .But for windows 7 it is fine no disturbance but after upgrading to win 8.1 it crashes frequently. what may be the solution??
and after the system crashes the dedicated graphics will also disappear. but for the drivers of windows 7 it works smoothly
