Time to see if you have installed Malwarebytes. Since last year is producing defective software that impacts heavily the memory, and system resources. Version after version, and update after update they are unable to solved the dammed problem.

Today, after yesterday more than 6 crashes, I uninstalled the beast. Guess what?

Zero crashes on my system for the last 12 hours.
