Nowadays, modern computers are built to handle frequent shutdowns and restarts. During their five- to seven-year lifespan, they can handle 40,000 on-off cycles before failure. So, you can rest assured that unless you are powering down your computer every two minutes, it’s highly unlikely you will ever reach that limit (via EnergyStar).
Another great reason to shut down your devices often is to let your computer have a chance to clear its RAM so you can have a fresh start every time you work. When you don’t have enough RAM space, programs and apps are sluggish and less efficient when in use. By regularly shutting down your computer you get to resolve any existing issues your system may have and will stop new problems from arising.
Finally, rebooting your computer is great for triggering much-needed updates from Windows or Mac Operating Systems that you need to keep your computer performing at its best.
