Computers are wonderful machines. Ever since they have been invented, they have allowed us to do tasks, which would have been downright impossible without them. The overall development of the modern world, science and technology owes a lot to the work accomplished by computers, which are now indispensable for the modern man. Nowadays, computers can be found in every home just as they are available in offices, laboratories and any other location you could think of. This is why it is important that you should know not only how you could operate them, but also how to fix some common issues when they will refuse to work.
The single common issue with computers nowadays is that they will not boot. Before calling a computer technician or taking your laptop to a centre for laptop repairs. It might be a wise idea to check the computer on your own. Sometimes, you can fix some simple issues at home by yourself, without any technical assistance whatsoever. Firstly, be sure do some tests as follows:
• Check your laptop battery – This might seem silly, but your battery might already be past its better days. A dead laptop battery can cause your computer not to boot if it cannot provide enough current or if it cannot hold enough charge. The easiest way to check is of course to plug your laptop directly to the wall socket. If the machine works just fine then, consider replacing your laptop battery
• Problems with the PSU – PSU stands for Power Supply Unit, and it is the device, which converts the A/C current that comes out of your wall socket into D/C current for your computer to use. A failed or failing power supply can definitely cause problems with booting, although most of the time they can make a computer reboot at random. Either way, try to swap the current PSU inside your computer for a spare and see if your problem persists.
• Hard disk failure – A failed hard disk can corrupt system files or make them inaccessible, which means that you won’t be able to boot into the operating system at all. If your hard drive fails, your only option is to replace it with a new, working one and if you ever need to recover important data on your failed drive, you might need to contact a company providing data recovery services.
• Try booting in safe mode – If you are running a Windows operating system, you could try to boot in safe mode to see whether there is a newly installed program or piece of software causing a conflict. In safe mode, only the bare necessary programs are loaded, and if you successfully manage to do it, you can undo any recent installations and revert to previous state. Scanning for viruses is also recommended, if possible.
• Reseat your hardware components – In a desktop machine, remove the casing and check whether any connections are loose. Additionally, blow off any form of dust that has settled on hardware and try to reseat devices such as RAM modules, VGA cards and other expansion cards. Beware that you run the risk of electrocuting yourself (and even damaging your hardware) if you forget to disconnect power to your machine before doing anything (if you are not sure about what you are doing, however, you might want to skip this step).
