[Dell desktop around 5ish years old; Win10; Thunderbird & Gmail; Google Chrome & Firefox; MS Edge which I don't know how to get rid of....]
My computer flickers frequently all over my 2 email programs, WordPad, Google Chrome, Firefox, the cursor...even in some websites too - impossible to complete any work. Almost always all at the same time.
Also vertical scroll bar at the right margin suddenly rushes down at maximum speed, by itself, taking with it all or part of any text or picture I happen to have, or in the middle of my typing or any other task I happen to be doing.
It does 101 chaotic things, like rapidly changing the pages, and/or files multiply themselves and trying to delete them generates more multiples ... and yes I lost many files through this thing.
I had a techie come and (my luck) my stupid computer didn't do anything so he left. He told me he's never seen what I described and he has to see it. So how can I be sure that the next techie I call has already experienced it, or that he sees it when he arrives?
I'm desperate, this is maddening and hope someone in this helpful forum maybe has seen or experienced this weird conduct and could somehow help me? Thanks so very much!
