Windows 10: Black flickering bar at the top of the screen and general screen lags- help!

This literally started a few minutes ago and I’m far too scared to attempt a random fix- I’m not entirely sure how to explain it, it seems to be an issue with just the screen but every few seconds the top of the screen will have a faint black bar across that flickers and will lag a bit- so if I try to move the cursor or minimise an app or chrome you can see a slight imprint of the page it eventually works but every time i try to make a move on my laptop it comes back again-I have windows 11 on a HP Zbook firefly 15 g7

Black Flashing Screen Problem Persists


First allow me to apologize if using this incorrectly... windows 10 HP pavilion... have a flickering black screen on start-up that corrects itself then re-occurs at various times... there is a 1/4" white flickering line on top of black flickering screen and at times also on bottom of screen. Have had Windows 10 since first offered and have had no trouble until this began a week ago... I have read and read again all the self-help and honestly do not understand... I have most limited computer skill and called HP for help... would cost me 139. for online help...I am an old gal living on minimum set income and declined their offer. Hoping this forum will be able to help me. I would appreciate any simply explained step-by-step instructions on correcting this black screen flickering issue. Thank you for any consideration.
