Getting flickering , see green lines going across stops stays good for a while and does it again

[EssexKid]

I have an HP stream, just recently upgraded to windows 11. Every now and again the screen flickers with lines, some appear to be green in colour going across and then it stops. Sometimes if I just touch the screen lid it stops. I have my computer hooked to a monitor the flickering does not show up on the monitor. I cannot recall if the flickering was there prior to upgrading to Windows 11. I keep my computer power cord plugged in all the time and when not using the computer I put it in sleep mode. Thanks in advance for any help on this issue.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Have you updated Graphics and Chipset drivers?

Let’s try these steps to resolve the problem:

I recommend you attempt to access the BIOS screen by tapping on F10 while the computer is restarting, If the issue persists in the BIOS screen which is outside windows, it would confirm a hardware failure.

Hope this helps! Keep me posted for further assistance.
