I updated Operating system 8.1. to my HP Envy 17-2100eo. It is working fine but the display is turning to black. I cannot see if it is updating something or not. I have removeed and reinstalled display drivers. After all, the issue seems to pop up evrytime something new is updated/installed. I just installed Adobe Reader and now after restarting totally black.
How to get rid of this blackness?
