Screen showing snowstorm and flickering lines since W10 update - unusable

[Elmo1983]

Following update to Windows 10 build 1903 when restarted the screen is no longer usable. Tried resetting through Windows Recovery Environment and reboot in safe mode but neither worked, screen still stays the same. Not sure if the graphics driver may need updated but unable to do anything. PC is just over 4 years old but the model number did not appear on the list of tested models for the Windows update.  Any suggestions would be most welcome!

@Elmo1983,

Welcome to the HP Support Community!

I reviewed your post and I understand that you are facing issues with the display after Windows update.

Don’t worry, I assure you I will try my best to get this sorted.

I recommend you try boot to the BIOS by tapping the F10 key on startup and check whether you are able to duplicate the issue in the BIOS screen.

Also, try connecting an external monitor to the computer and check whether the display is working fine on the external monitor.

Let me know how it goes and you have a great day!

If you wish to show appreciation for my efforts, mark my post as Accept as Solution. Your feedback counts!

Cheers!

I tried plugging in a separate monitor yesterday - well a tv as it was all I had! The display was fine on that so far as no lines or flickering present. I couldn’t see the task bar along the bottom and the edges were cut off - I’m assuming this was purely to do with the resolution of the tv. 

I attempted to upgrade the graphics driver but it was up to date. 

Im not sure what you mean by duplicate the issue in the BIOS screen? I was in and out of safe mode using the external monitor/tv but the actual PC screen didn’t change at all.

Already tried that. I tried the 1909 build update with no change. No other updates were available via windows or HP.  I also tried resetting the PC but my recovery usb drive didn’t work. Could then only restore back to between the 1903 and 1909 builds so no help there either. I’m at a loss as I’ve tried everything I can think of.
