The computer does not turn on, what should I do? This is one of the most popular searches in today's search engines. Let's try to figure out why the machine refuses to function.
If you asked yourself this question: “What should I do if the computer does not turn on?”, Then remember: the main mistake of almost every computer owner who has stopped turning on is that he literally immediately begins to perform troubleshooting procedures (although they he is not yet known) in an absolutely chaotic, wrong order. As a rule, this process ends with a complete fiasco ... In memory, all completed "troubleshooting" steps are gradually erased, the machine continues to refuse to work, the result is zero.
Next, step-by-step instructions for the actions of a beginner self-taught computer master will be given. I recommend not changing the above procedure.
Step # 1
External inspection of the machine. You will be very lucky if the first step helps to answer the question of what to do if the computer does not turn on.
So let's get started. You do not need to try to turn on the PC without doing the following:
- The main power cable must be connected to the network. (Performing this manipulation makes sense in the presence of 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 connected securely.
- Check the position of the system unit switch, if any. As a rule, it is located on its back side. The switch must be in the on or 1 position. With a tight movement, you can judge that the button has sunk, to release it you need to use the tool.
Turn on the computer. Does the car work? Congratulations!
The question of what to do if the computer does not turn on remains relevant? Do not despair and continue!
- Disconnect all external cables (keyboard, mouse, USB ports, speakers , etc.) from the computer. Release the drive. Only a monitor and power should be connected to the machine. Check the operation of the monitor using the indicator of activity indicator on it. In most cases, this is a small colored light in the lower right corner, which should be lit or blinking when working properly. It is also necessary to check the monitor settings after checking the activity. In particular, brightness and contrast. It is possible that the computer turns on, just the image on the monitor is not visible due to a malfunction in operating parameters.
How are things now with the question of what to do if the computer does not turn on? Open? Then continue!
Step number 2
Basics of repairing a personal computer, internal inspection.
- Remove 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 working state of the computer, namely: the motherboard, processor cooler, processor, memory module, video card. Remove the remaining elements (all boards, extensions, additional devices). In this case, in no case should the power be supplied to the machine. So, 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 connecting them one at a time, naturally by connecting them to a de-energized machine. With this method, you will be able to establish when the device was connected when the machine refused to work.
In this case, options are also possible: either this part is defective and requires replacement (repair), or the problem is in poor contact with this part.
What to do if the computer does not turn on further? We continue.
- Check power supply. To do this, pay attention to the LED and the green indicator on the motherboard. If the power supply is in good condition, it should burn.
- Some motherboards have protection that prevents the system from starting if the processor fan fails. So it is worth paying attention to him.
- Listen for sound signals from inside the system unit. They are? Most likely, in this case, the problem arose with poor contact of the memory modules or the video card. It is possible that one device from them is generally out of order.
If after that you were able to answer the question of what to do if the computer does not turn on, then you can congratulate you on the acquired skills!
