internet page skips down on its own

i have a system with a weird phenomenum
a desktop running W10, + defender and AV does the following :

when i open up an internet page with EDGE (startpage = google, then hp system + drivers, and i'm llooking up drivers or manual, the page starts skipping DOWN, say 1/2 page, stops several seconds , then skips DOWN again, etc

This is very frustrating , so i'd like to know what can cause this - and put a stop to it
it also happens on other pages than HP -  and i only have it happening on this system
i installed all systems myself - clean
i use a PS2 keyboard, and wired USB mouse - no wifi

ideas? ? ?

Just one..

Reset Edge. Could kill two birds with one stone here.

See here:

I'd also check if the behavior exists when booting into Safe mode with Networking.. I think there's an extension or add/on that's gone rouge on you somewhere.

jeez - now it does not do it anymore…
all i did was swapping the usb mouse with another one - to see if it was a mouse fault (or cable) since it resembled a left mouse click
will wait a couple of days  to check further

Interesting. A bad mouse never occurred to me, though thinking retrospectively, it's a valid troubleshooting step. Well done and hope its resolved for you :)
