OK, lookee....I say this HAS to be hardware. It survived a repair reinstall of Win 10 and a clean reinstall of Win 10.
Below is more information than anyone could want about the GPU in this machine. I don't understand any of it!
Meanwhile, I have found out that, in spite of the standard specs for a Dell 3541 laptop calling for an Intel HD Graphics 5500 card, if that is a card, mine contains an AMD, as specified below. While I was here twiddling my thumbs in the middle of this post, I reloaded the package I'd deleted, which I think included drivers.
So the GPU/Card/whatsit is presumably all up to date.
I don't know. if I had money to toss around I'd just get another computer and put paid to the problems.
Really, does anyone know anything about this that makes any sense?
It's a not-exactly-unheard-of problem: google "search window pops up" and you will find threads on the subject going back several years. Some folks seem to get it solved by disabling some of the tapping on their touch pads; but my touch pad is always turned off.
I have been through lots of diagnostics, "repair broken files," alla that. Now, it seems, I've done what could be done with the GPU. Got a Microsoft volunteer(good one) running me through more diagnostics; but read the very top of this post and see what I think the likelihood of fixing this that way is.
This is a Hardware club. You tell me, in your collective experience are there such difficulties where nobody really can say---Oh! That's the Autonomous Popup Problem with the Associated Visual Glitches. You just
1) press the Windows Key 14 times
or 2) throw away your computer.
What the heck, folks! ANY wisdom?
