Why Do Computers Break?

We know computers always break at the worst possible time, but what exactly prompts that failure? It’s easy to think it was something you did since you were using it at the time, but while your online gaming frenzy might cause a temporary crash, normal user actions are rarely the cause of a broken computer.

Physical Damage

Accidents happen, but they don’t always mean you need to buy a new computer. As an electrical item, liquid spills are a big problem. This could be anywhere from a spill on the keyboard or next to the computer, going overboard with the screen cleaning spray or even a flood that reaches the computer. Laptop users need to be especially careful when choosing their work surface, as cafes and kitchen tables often have small puddles left behind. If you’re lucky and the liquid didn’t fry the circuits, ongoing corrosion is still likely, as is stickiness to gum up the internal parts. Similarly, a dropped computer isn’t going to be happy, nor is one that’s been knocked around. Even a light thump of frustration can cause loose cables, disconnections and internal damage.

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. This is one of the main reasons we always recommend commercial grade computers over consumer grade machines when budget allows.

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. For optimal protection, we recommend a UPS (Uninterruptible Power Supply). A UPS can block the surges and fill in the low voltages to keep your computer running smoothly.

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. Even if your computer doesn’t shut off from overheating, the additional temperature still reduces the life of your components, so keep it cool!

Hard Drive Failure

Your data is stored on a hard drive, and if you’ve got a mechanical hard drive (most people still do), it works a bit like a record player with a spinning ‘platter’ and a needle (read/write head) 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 always keep data backed up so when (not if) your hard drive fails, you are prepared.
