We know computers always break at the worst possible time, but what are the most common reasons for that failure? It’s easy to think it was something you did since you were using it at the time, but even so, normal user actions are rarely the cause of a broken computer.
Physical Damage to the Computer
Accidents happen, but they don’t always mean you need to buy a new computer. As an electrical item, liquid spills are a major problem, yet happen all the time. This could be anywhere from a spill on the keyboard to going overboard with the screen cleaning spray – it doesn’t matter too much if the keyboard is cabled or Wi-Fi to a PC, but if it’s part of a laptop then that liquid can cause serious problems.
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 of the Computer
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 barely be 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 it’s luck of the draw with how the computer was manufactured, and quality does play a big part in how long it can keep churning and the phrase “you get what you pay for” does apply in the I.T. world. That unusually good deal may not be the best thing for you to spend your money on.
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 but they can easily break your computer.
A good surge protector can guard against mild increases in voltage, but quality is key as we found recently with a customer whose PC could not boot in Gilmorton. Even though the PC power cable was attached to an extension that had a ‘surge protected label’, it was in fact a low quality one and the power surge just went straight through it.
If the surge is bad enough even a good quality surge protector may not be able to take the charge, but you stand a better chance with one than without it.
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 temperatures, the more likely your computer is to die.
This is especially true for laptops and many times we see customers using their laptops on soft surfaces such as cushions or quilts, which of course simply blocks the vents and increases internal temperature. When using a laptop, wherever possible keep the vents clear and use it on a hard surface.
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 mechanical arm that reads it (although the ‘arm’ doesn’t actually touch the surface).
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. Whilst it may be a sudden breakage, take note of any strange noises or repeated crashes and back up your data in advance.
Like a car, your computer needs to be serviced. We can check your computer both physically and its software, to make its running right and will keep on working for you. Give us a call on 01455 209505.
