My computer monitor is miraculously lacking in fist-related cracks

My computer monitor is rapidly breaking down.

It’s a huge iF281D something or other, and it overheats, badly. In warm weather, when I’m playing a graphics intensive game, or when I’ve just had it on for too long, the screen goes black briefly. Since my sound is running through the built-in speakers, that shuts off, too. Then, anywhere from half a second to thirty seconds later, it pops back on. Then, a few seconds later, off again. Back in the fall, it was a minor problem that only happened once or twice a week, and I could stop it with Ctrl+Alt+Del. (Dunno why, changing to the menu screen it brought up immediately stopped the process. I didn’t have to do anything else, I’d just get back to what I was doing.) Now, it’s a daily occurrence. I recently had to spend nearly four hours watching a movie, because I had to turn the monitor off to cool down every ten to fifteen minutes. (It was a hot day, to be fair.) Plus, the monitor turning off and on unexpectedly is really, really jarring to the eyes. They are not adapted to that. This is obviously extremely frustrating, but it is not without unexpected advantages.
