What to do if your computer does not turn on?
Computer in modern life – is more than just a technique that helps in the work.Most often, the computer becomes a necessary and indispensable part of life.So when the computer is not included, or set, your computer will not boot, it can seem more than a challenge, especially when urgent work is not completed or other important business.But do not worry about it too much: when the computer fails to start or how to say “computer will not turn on,” you need to concentrate and perform a series of actions that will conduct an independent diagnostic computer to find out possible causes of failure.
Reasons why the computer will not boot, can be set:
the absence of line voltage;
damage the power cord or extension cord;
the failed (burnt) or exhausted the resources of power supply;
defective motherboard;
damaged contact between the cables or components in the system unit;
a virus;
loosely connected loops devices;
improperly installed boards in the system unit;
and dozens of serious and not very reasons why not start your computer up to the accumulated dust inside the system unit.
What should be done to find out the reason why not start your computer?The first thing to check the voltage on the network.To do this, simply plug into an outlet that feeds your computer, automatically working device (such as a desk lamp, kettle).If this device works – supply voltage and there really is “complex” is not loaded for some other reason.
Then, in the same way checks whether the power cord.Sufficient verification test for the first two reasons of malfunction of computers is when the power indicator lights up on the monitor.If it is intermittent flashes (on some models glows a different color) – with electric power all right.
If all the above steps did not bring solution to the problem, you need to call a specialist – Further diagnostic computers can only be a qualified employee of a computer service center.If your knowledge of computer repairs are reduced to the replacement of a mouse or a monitor, do not try to diagnose yourself – you can inflict even greater damage to your computer.Call the customer service computer experts, and expert computer help to hold a full and accurate diagnosis of your computer, identify the reason for not include “complex”.
The only thing you can do more before calling a service to our computer services – is to try to decipher the signals BIOS.
