Hi a3000master,
Welcome to the community!
In order to assist you with the issue I would like to know:
- Does the computer have Integrated Intel HD Graphics card or Discrete NVidia GeForce GT 525M Graphics card?
- Did you install the latest drivers for the graphics card?
Also, please refer the following link for instructions to run diagnostics on the computer to rule out hardware failure: http://dell.to/19cWLsz
