If you need to run a time-consuming process like downloading or rendering, you can leave your PC on 24/7. For the most part, your decision depends on your situation. We recommend shutting down your PC at least on occasion. So what’s best for your devices? Should you shut down your PC every night? On the other hand, you expose it to power surges for longer periods by leaving it on when you’re not actively using it and your electrical bill will be significantly higher. For example, if you don’t shut down your PC frequently, you can start using it as a server or for downloading large data files. You need to consider these possible risks and weigh them against any advantages.
