Hi BrownKibbe,

I am sorry for the inconvenience, try updating the BIOS, Chipset and video driver using the link below.

Please connect the Ac Adapter while updating the BIOS and do not use the system once the update is initiated and until the system restarts completely

Please update the driver in the exact order. Also run a hardware diagnostics to check if the hardware is working as designed, you can release static power and run hardware diagnostics in the system. Follow the steps below.

Switch off the system; remove the battery, ac adapter and the power cable. Press and hold down the power button for thirty seconds to drain any excess static power and run the test. Restart the computer and at the Dell logo screen, start tapping the F12 key a few times until you see the ‘One Time Boot Menu’ appear.

At the one time boot menu, press the down arrow key to highlight ‘Diagnostic’, and then press Enter to begin the hardware diagnostics.

If the test fails, please make a note of any error codes listed. You can also refer to the link below.
