When it shuts down, the system goes through and closes any open programs (often prompting you to save first), then gradually cuts power to all components. It’s a methodical process that seems quite fast to us but is actually made of 100+ intentionally ordered steps. If there’s a sudden blackout or you hold the power button until it turns off, it means the steps aren’t followed and damage is possible. The second option is to put your computer to sleep. This can be triggered by an automated timeout or a user click. Your system uses a special type of memory called RAM to hold all your running programs exactly as you left them but use minimal power. The hard drive stops spinning, the graphics card lets the screen go black, and even the system fan slows to become almost silent. When you wake it by moving the mouse or pressing a key, it ‘wakes’ again almost instantly.

Reasons to Shut Down

A switched off computer isn’t drawing power which is a tick for the environment. But shutting down is about more than saving power. It can sometimes give improved stability over a machine that’s been running for days/weeks. This is because every time you shut down, you give your computer a chance to clear out all temporary junk files it’s been carrying in memory. It also triggers various health checks on startup that may otherwise be missed, important routines like checking for updates or scanning for viruses. It’s certainly more convenient to spend an extra minute booting up than lose everything to a cyber-attack. For older computers or those under heavy strain like gaming or video editing, shutting down also provides a necessary chance for the components to cool down.

Reasons to Sleep

Speed is the big selling point here. You can literally sit down and start working where you left off without the delays of bootup, finding your program, opening your saved files, scrolling down… it’s all right there and ready. You can even tell it how long to wait before putting itself into sleep mode, just in case you get called away and forget. Windows updates still run in the background, so that’s okay, but it’s important to note that your computer might get stuck waiting for a reboot that never comes.  Those pending updates may stack up, ineffective until it either forces a reboot or becomes unstable enough that you give in to a restart.

The best method is….

Since the whole point of having a computer is that it’s ready to work when you are, we recommend shutting down at night when it’s definitely not in use but using sleep mode during the day. Updates will get all the rebooting they need, memory is refreshed for the new day, and you’ll get the best of both worlds – speed and stability.

Age

Computer parts have an expected lifetime, especially moving parts like fans or mechanical hard drives. Some computers can run 24/7 for up to a decade, while others can be barely used but fail within warranty. When age is the issue there are usually early warning signs like extra noise or slowing down, but the actual ‘break’ generally happens when you go to turn the computer on, perhaps after a crash or overnight – either it makes a valiant effort before giving up, or nothing happens at all. Sometimes lasting age is the luck of the draw with how it was manufactured, and quality does play a big part in how long it can keep churning.

Power Surges

We like to think electricity is a constant stream that never varies, but computers are particularly sensitive to both surges (too much electricity) and brownouts (not enough electricity). You might notice the lights dimming or flickering during a brownout, or glowing just a tad too strong during a surge. These variations never last long, and they’re not something you can control unless it’s just your house (it’s worth checking with your neighbors), but they can easily break your computer. A surge protector can guard against mild increases in voltage, but brownouts and strong surges will still cause damage.

Heat

Overheating is a big contributor to premature computer death. Some computer parts run hot and need plenty of cooling to keep them working. You might not feel it from the outside, but internal components can rapidly build up heat that needs to go somewhere. When your airflow vents get blocked with dust or pet hair, the temperature continues to increase until components literally bake themselves to failure. At set temperatures, the computer will automatically switch off to try and cool down, however the more often this happens and the higher the temps, the more likely your computer is to die.

Hard Drive Failure

Your data is stored on a hard drive, and if you’ve got a mechanical hard drive (most people do), it works a bit like a record player with a spinning ‘platter’ and a needle that reads it. Small bumps, liquid, age, surges and overheating can all trigger hard drive failure. Along with making your computer unusable, hard drive failure means your data is also lost. While sudden breakage might leave you surprised, take note of any strange noises or repeated crashes and back up your data in advance.

What to Do if Your Hard Drive Fails

If your hard drive is going bad, chances are strange things are happening and you’re a little panicked. It’s where you put your digital memories, your household files and maybe that thesis you’ve been working on for months. As far as you’re concerned, that hard drive IS the computer and failure is not an option. Perhaps it was overheated, knocked around or came from the factory with a flaw.

Sorry to say, but eventually all hard drives will fail. So how do you know if it’s definitely the drive and what should you do?

Corrupted files: Sometimes a file won’t open because the computer says it is corrupted. Some essential pieces of the file are missing, and unlike a book where a missing page is only inconvenient, it’s a deal breaker for computer files.

Noises: You’re familiar with the normal noises your computer makes, but as the hard drive fails the noises can change. You might hear clicking, grinding or even a sci-fi phaser noise. Noises will get louder or speed up during heavy file access.

Whenever something is clearly wrong, the key is to stop and turn your computer off. Continued use can result in more data loss. Even if you don’t have a backup yet, turn it off now because the large task of backing up can cause extra strain on an already delicate hard drive. It’s tempting to hurry and try to get a quick copy of your files, but in these cases, it’s not about time – it’s about the extra spinning, scratching, warping and electrical charge, all dissolving your precious data with each access.
