What should I do if my computer does not turn on?

If the computer does not turn on, first check the monitor. Perhaps, the fixing of the plug is loosened, and the download process is simply not displayed on the screen. Check the network cable and the network connection. Before taking drastic measures, you need to make sure that all the necessary manipulations are made.

Here are the possible reasons that the computer does not turn on, do not squeak, does not give signs of life:

• The network filter is disabled;
• The power supply is disconnected;
• There is no contact with the network;
• Weakened the fixation of components (this could be a video card or monitor, motherboard or other components).

Often, the cause of failure is the failure of the power supply. In most cases, it has to be changed, since repairing modern power supplies is quite difficult and expensive.

However, it happens that the computer turns on, but does not boot. This may be due to the failure of the video card. To check for suspicion, remove the card and install it in another system unit. If it is working, the cause may be in the BIOS settings failure. In this case, you should check how the program is debugged.

To do this, at boot, press the Insert key - it will help to reset the changes and return to the default settings. If the key does not work, you can try to troubleshoot the problem manually. To do this, Clear CMOS jumper, which is located on the motherboard, must be transferred to other contacts.

Often the cause of failure of the load is removable media or floppy disks. Therefore, before you start the computer, you must remove all third-party disks. If the computer does not turn on, it is recommended to pay attention to the special sounds of the system unit.

One signal indicates an error-free download, and if the video card is faulty, the system unit will give one long and three short beeps. The absence of a keyboard connection is reported in the same way as a video card malfunction. If the graphic subsystem is faulty, one long and two short beeps will be heard.

When the computer is frequently rebooted, you should pay attention to the memory module's serviceability. One way is to install special software. If the computer is overloaded with such frequency that the installation of the software is impossible, it is better to temporarily replace the RAM. If the problem disappears, then the problem is still the RAM.

It happens that the computer does not turn on because of the cooling. In this case, you need to check the cooler and BIOS settings.

But if the computer is functional and the operating system does not boot? This may be due to the fact that the system was damaged as a result of a virus attack or an unauthorized shutdown. In this case, the files necessary for proper loading are either erased or damaged. It is necessary to try to start the computer in safe mode, restore the previous state and perform the restart in normal mode. If the computer still does not turn on, it is recommended to check the startup. Perhaps some program interferes with the normal launch.

If all attempts to restore the computer to life are vain, you can decide on extreme measures - reinstall the OS.
