What should I do if my computer does not start?

Probably, every user at least once faced with this situation, that the computer does not start. In such cases, if you act on the algorithm below, then you can easily and quickly find a malfunction, and in many cases and independently eliminate it.

First of all, it is necessary to check the reliability of the connection of all the PC cables, if any connector has moved away, it must be corrected. Very often it is the outgoing connector that causes the system unit to be disconnected.

If this does not help, we move on. In the event that the computer turns off or hangs after displaying the primary screen saver, then the problem most likely lies in the violation of the software. You should reinstall the system or restore it from a backup (if any). If you do not know how to do this, then invite a specialist.

It happens that the computer does not start, and there is no reaction to pressing the power button, in this case, most likely, the power supply unit was burnt. In the store of spare parts you can buy a similar one and make a replacement.

Also, it is possible that the computer does not start and still beeps. This triggers a fault warning system . Find out what exactly does not work, you can, using the decryption table for the audio signals for BIOS of your brand. Based on the type of error, you should first check the power and the connection of one or another unit, and then, if necessary, replace the defective part.

It is possible that the PC starts up, runs for a short time and turns off. This may be due to the activity of virus programs or the overheating of the central or graphics processor. In the first case, it is necessary to clean the system in order to remove malicious programs. In the second, the cooling system malfunction must be rectified. To do this, make sure that all the fans (processor, power supply, video card) rotate after starting. If this does not happen, then either the power is missing or the fans themselves do not work, then they must be replaced. Perhaps, the problem will be solved by cleaning the system unit from dust and changing the thermal paste.

In the case when you have done all these operations, and the computer does not start all the same, consult a specialist. When self-checking the components of a PC, do not forget about the safety precautions, never disconnect or connect the components of the system unit while the power is on.

If the PC is still under warranty, you should not do anything yourself except to check the cable connections and reinstall the system. Carry the system unit to the warranty service center, they will find out why the computer does not start and fix the problem completely free of charge, if it is caused by the failure of any part not through the fault of the user.

Also it is worth remembering that most often the computer does not start due to the fault of the user. This work without anti-virus software and the lack of equipment such as an uninterruptible power supply unit or at least a voltage filter, an occasional dust cleaning and replacement of thermal grease. All these factors increase the risk of damage to your PC.
