Bah, why doesn't the tablet app have a simple reply-to-this-thread button, instead of presenting ONLY a quote-a-whole-message button? I found a Reply option in the stack-of-lines button at the top of the app window, and figured THAT was a reply-to-this-thread button, I then posted two paragraphs of stuff, hit Send, and.... nothing happened. It didn't show up here in this thread, it didn't show up as an IM to myself, and it didn't go to email, so I don't know where it went. Anyway, trying to remember what I said, so I can post the information again:
If you meant did I upgrade from, say, Win7 to Win10 this week...? No, my upgrade INTO WIn10 from another version of Windows was probably a couple of years ago. No, the recent one was simply Win10 progressing into its next update. Would running the ISO thingy on it still fix it, though?
On a different note, a few moments after I posted the previous message in here, my machine locked up again. This time I had HWINFO installed and running, and also had a system-monitoring program from the makers of my video card running. On HWINFO it showed the CPU, ram, HDDs, and whatnot all within their expected temperature ranges at the moment of the hang. The video-card monitoring program also showed the card within its normal temperature range, and also showed the fan running at 44%, which seems to be the normal, expected amount when its not working hard.
