Problem at first start up (after reboot the problem vanishes)

[Andrew_Kriss]

Hello everyone and thank you in advance for your help.
The problem occurring on my HP pavilion is as follows:
At first startup already from the login screen the screen flickers, turns off and on several times. The problem is only in the display, as if I do something with the keyboard in the very short moments when it turns on I can see what I have done.
If in those few seconds I can reboot the laptop on the second reboot it works perfectly. In some cases it stays dark for a long time and I am forced to restart with the power key, but if I have some work open unfortunately I lose all the unsaved material. This problem has been doing this for the past few months. I am unable to determine if it is related to the upgrade to windows 11.
All video drivers are up to date and HP diagnostics for video and stress test detect no problem.
The general diagnostics also does not detect any problems.
Can anyone give any suggestions on how to fix it?

Thanks
