It looks like your system is currently running switchable graphics; this means that your computer runs Intel graphics and Nvidia at same time. This type of computers do not use generic Intel drivers, they require special drivers from the computer manufacturer. I would highly recommend you contact your computer manufacturer for further assistance.
I appreciate you taking the time to reply, Allan, but the information you have provided is, quite simply, wrong.
Please see this thread that I posted a couple of weeks ago: Nvidia Optimus vs switchable graphics misinformation
More importantly, please take the time to read and absorb the Optimus White Paper linked within. This fully explains the difference between "switchable graphics" (circa 2009) and the dual graphics solutions in use on today's notebooks. You will see it stated quite clearly on several occasions that Nvidia graphics cards with Optimus in dual graphics solutions do NOT require OEM drivers for the Intel integrated graphics running alongside.
To further support this, I've run the Intel Driver Update utility on my laptop and it not only recognises the driver that was pre-installed as a standard HD4000 driver, but it also does not indicate at any point that it is an OEM driver (the utility claims to be able to do this).
I don't mean to sound hostile, but it is incredibly frustrating to come to a technical support forum and to see the same incorrect information being provided as a 'solution' to every other issue raised.
