Hi ,
My name is Sudheer K and I work for the Social Media and Community Team at Dell.
I would like to give you some basic instructions regarding the issue you are facing.

Step 1: Check the video card on the system and tried reinstalling the video card drivers from device manager and restart the computer. Try updating the required video card drivers from support website or vendor website as well.

Step 2: Update the required bios, chipset also from support website.

Step 3: Try setting the power options to default as well.

Please provide me the system model if you need futher help on drivers as well.
