As per the specifications you provided, your system features switchable graphics which requires and uses a special driver to enable such feature. That driver is only provided by your computer manufacturer who implements that feature in your system.

I suggest you to contact DELL for further troubleshooting assistance on installing the drivers they provide for that system.
I suggest you to review the information that is posted on the following article:
It explains about switchable graphics and why you should not use generic drivers.
