that was strange

I was up in the middle of the night, and occupying my time watching a YouTube clip of a John Oliver segment, when all of a sudden the picture froze, though the sound kept sailing on. As this went on for a while, I force-closed the browser, re-started it - the tab was cued to just before the picture stopped - but it only played for a couple of minutes before this happened again. Repeat, rinse, and again.

I got through the entire video eventually, but then the browser - I use Firefox - started freezing whenever I tried doing something else. Rebooting the computer didn't help. I'd start Firefox, it'd work fine for a couple minutes, then it'd freeze - and it wouldn't unfreeze; at one point I left it alone for an hour to see what would happen.

Then it got to the point where it was freezing as soon as I'd start it. Before it got that far, I'd searched for help, and the only clear advice was to uncheck something called hardware acceleration, which I'd already done to solve some other problem. Beyond that was things I couldn't do, and I was thinking about taking the computer in to the software wizards when they opened in the morning, when all of a sudden the problem stopped, and the browser works fine again.

Well, this computer is nearing the end of its lifespan anyway, so sooner or later I'll have to do something, but in the meantime I'm just going to hope this doesn't recur. If I'd been asleep when I should have been, I'd never have noticed anything.
