Hello, I recently bought a used dell e5440 I formatted a drive put a fresh install of windows 10 and it seemed to be working fine. However I noticed that the screen would flicker and then go to a black screen. I noticed that certain games forced the issue. I updated all the drivers and went through both dell's LCD checks and they both seemed to pass. When I plugged in a external display, I get an image on the external display. When the screen goes black both fan and drive run.
