Each owner of an electronic computing system should be mentally prepared for the fact that from time to time it will have to solve rather specific problems. For example, to understand why the computer does not turn on.
And not only possess theoretical knowledge, but also be able to independently fix the breakdown, if, of course, this is possible. Typically, this malfunction manifests itself as follows: after power is applied and the power button is pressed, the computer does not turn on (the black screen of the monitor is evidence of this). That's what we’ll talk about today. Just note that you should not rush to repair shops, since the cause of the failure can be commonplace, and the payment for work can be very tangible.Start line
The computer does not turn on? Black screen? Do not panic! First you need to check the power status of the system unit. Most computers are now connected to the network using a Pilot type extension cable splitter, and the fact of power supply is controlled by a luminous signal light on it.
However, due to the design features of some models, a situation may arise when electricity is not supplied to the device. The solution is simple: switch the plug of the system cord to another connector. Having repair skills, you can subsequently restore the extension cord by performing an audit of the internal elements.
The next reason why the computer does not turn on may be a loose contact at the point where the cord connector is connected to the system unit. You must remove the cord and reconnect it, you can also try to connect the corresponding cable from the monitor to the system unit (usually they are identical).
Cooling
Many motherboards have a logical mechanism that interrupts the power supply in the absence of signals from the cooling system fans. So, everyone who has ever wondered why the computer does not turn on knows that you need to open the case cover and make sure that the fan blades (especially the processor blades) rotate, and are not blocked by long-term dust.
In other words, the components of the system unit should be cleaned from contamination.Button
