System reboot

If the system is working slowly, it’s often a good idea to close the programs you’re no longer using. You can try restarting various processes too.

When those things don’t help, try a soft reset. Shut it down completely, then restart after a short time.

It might be a good idea to check for viruses, too, but try the simpler steps first.

Of course, this is advice about your body and your mind, but it can also be applied effectively to various computers and devices too.
