edik9850, I had it too. Then I got rid, frankly, I no longer remember how. Now only the first minutes after turning on loads the disk, but it does not affect performance. After starting, I immediately start the game, it doesn’t lag anything.
I deleted the built-in as unnecessary, such as cropped Skype, Facebook, something else. Googled by the name of the most devouring process, you may find something useful. Or at least you will understand what kind of program it can be, you can delete it. At first I was also very upset, but now everything is fine.
