Since your 2nd screenshot show an Nvidia logo, then we must assume you have the Nvidia graphics chipset onboard your notebook computer.
Searching the Dell website shows three graphics chipsets that were used in that model notebook computer. The Intel Graphics Media Accelerator is in addition to the Nvidia GPUs.
From DELL:
Video Card
NVIDIA® Quadro® NVS 140M5
High end graphics solution specifically designed for graphically-demanding applications like 3D modeling and video-editing. Delivers scalable flexibility for investment protection.
NVIDIA® Quadro® NVS 135M6
The NVIDIA Quadro NVS 135M offers all the latest graphics technology to produce extraordinary visual effects, robust wide-aspect LCD support and compatibility with all major business applications.
Intel® Graphics Media Accelerator X3100 (Up to 256MB shared) The GMA X3100 graphics core is an intelligent and responsive graphics engine built into the chipset that is on the motherboard. This integration provides incredible visual quality, faster graphics performance and flexible display options.
You'll need to install either the Intel GMA driver to get the ball rolling. Go to:
Intel® Graphics Media Accelerator Driver for Windows* 7 64 (exe) or the Nvidia Quadro driver, which you can download here. It's called the Verde R285 Driver now:

Try the Nvidia driver first and see what results you get.
