What should I do if my computer does not turn on? The answer is here!

The computer does not turn on, what should I do? This is one of the most popular queries in existing search engines today. Let's try to figure out why the car refuses to function.

If you asked yourself this question: "What if the computer does not turn on?", Then remember: the main mistake of almost every computer owner who has stopped switching on is that he literally immediately starts to perform manipulations to solve problems (although they He is not yet known) in an absolutely chaotic, wrong order. As a rule, this process is completed with a complete fiasco ... In memory, all the performed actions "to eliminate problems" are deleted, the machine continues to refuse to work, the result is zero.

Next, a step-by-step instruction for the actions of the beginning computer master will be presented. I recommend not to change the above procedure.

Step # 1

External examination of the machine. You will be very lucky if the first step helps answer the question of what to do if the computer does not turn on.

So, let's get started. Do not try to turn on the PC without doing the following:

• The main power cable must be connected to the mains. (The implementation of this manipulation makes sense when there is electricity).
• Remove the main power cable from the system unit for a couple of seconds and firmly insert it back so that you are sure that the cable is securely connected.
• Check the position of the switch of the system unit, if any. As a rule, it is on its back side. The switch must be in the "on" or "1" position. With a tight movement, you can judge that the fuse button, you need to use the tool to release it.

Turn on the computer. Does the machine work? Accept sincere congratulations!

The question of what to do if the computer does not turn on remains relevant? Do not despair and continue!

• Remove all external cables (keyboard, mouse, USB ports, speakers , etc.) from the computer. Release the floppy drive. Only the monitor and power supply must be connected to the machine. Check the operation of the monitor using the activity indicator on it. In most cases, this is a small colored light bulb in the lower right corner, which, if properly operated, should light up or blink. And also it is necessary to check the monitor settings after checking the activity. In particular, brightness and contrast. It is possible that the computer turns on, just images on the monitor are not visible due to a failure of the operating parameters.

How are things now with the question of what to do if the computer does not turn on? Is it open? Then continue!

Step # 2

Fundamentals of repairing a personal computer, internal inspection.

• Remove the 2-4 screws on the left side of the system unit and remove the cover.
• Leave only the necessary parts of the system unit for the operating status of the computer, namely: motherboard, CPU cooler, processor, memory module, video card. Remove the remaining elements (all boards, extensions, additional devices). In this case, no power must be supplied to the machine. So, when performing this action, unplug the cable from the outlet.

After removing all the "unnecessary" components, try turning on the PC. If the machine is working, the reason is one of the additional devices. Try to connect them one at a time, naturally, attaching them to a de-energized machine. With this method, you will be able to determine which machine the machine refused to work with when connecting which device.

In this case, there are also possible options: either this part is faulty and requires replacement (repair), or a problem in poor contact with this part.

What should I do if the computer does not turn on and on? We continue.

• Check the power supply. To do this, pay attention to the LED and the green LED on the motherboard. If the power supply is functional, it must be lit.
• Some of the motherboards have a protection that prevents the system from starting if the processor fan is faulty. So it is worth paying attention to it.
• Listen to the audio signals from the inside of the system unit. They are? Most likely, that in this case the problem arose with a poor contact of the memory modules or video card. It is possible that one of them has failed at all.

If after that you could answer the question of what to do, if the computer does not turn on, then you can congratulate you on the skills you have acquired!
