Hello forum.
I have an HP Probook 4720 and 2 weeks ago I started having problems with it, more exactly blue screens and a few freezes (2/3), I though it was from my OS after that, one morning I power up the notebook and I have no image on my display. Previously to that I had no flickers, no weird lines on the display nor anything like that.
I connected an external display and it works, so it's not from the ram mem, the hdd has 3 days power up time. I reinstalled the OS, notebook's display still doesn't work, after reinstalling the video drivers and restarting windows won't boot up, only way is to select ''last known good configuration'' which removes the video drivers. Then I thought to check the GPU temp which is at 85/95 celsius, kinda hot.
What do you think is the problem? Can the video card be broken? If so why does the external display work? What can I try now? The screen is completely black, I mean it doesn't power up and displays a black image.
Thank you.
