I recently bought a new machine, and everything seems to be running fine–except, I keep having this problem with CPU activity. As you can see from the enclosed jpgs, all eight cores can be running at 40 percent, yet there’s nothing obvious running in the system monitor. I’m not sure what’s happening. If I shut down all open programs and leave it a while, it usually stops, and it’s a purely intermittent problem, but I’m out of ideas as to what could be happening. It doesn’t happen under Windows 10, and it’s nothing as daft as the CPU activity being at the bottom of the monitor. In fact, I’ve included a picture of top to show the same result via a different monitor. Any idea what could be happening?
Out of curiosity, I ran a stress test on my machine, and everything seems to be running great. My computer details are in my signature.
P.S. There are two jpegs below: for some reason only one of them shows as expanded. You need to click on the other one.
