Sometimes the computer will encounter situations where it cannot be turned on. We have previously popularized the knowledge about computer motherboard indicators. Through the motherboard indicator, we can quickly determine which hardware is wrong. However, many newbies still have a headache when deciphering motherboard indicator lights, so this time I will directly teach a few fool-style computers. If there is a problem with the computer, you can try the following simple maintenance methods first.
monitor switch confirmation:
computer screen has been off. First, check the simplest monitor switch to confirm whether your monitor has forgotten to turn on. Although this is an extremely funny operation, the author has encountered many so-called computers that cannot be "turned on". In the end, it was found that the user forgot to turn on the monitor.
repeatedly plugging and unplugging memory:
troubleshooting the display switch. Usually, the computer fails to turn on because of memory problems. Loose memory and static electricity may cause the computer to light up. At this time, we need to replug and unplug the memory. Remember to wipe the golden fingers first after pulling them out to remove the static electricity.
is saved if it is lighted up
The premise of this method is that although your monitor screen is not illuminated, other hardware inside the host is on normally, which means that the motherboard and power supply are not broken, and the computer is still saved. If your computer does not respond and cannot be turned on, that is, after pressing the boot button, the motherboard does not light up and the fan does not turn, then plugging and unplugging the memory is basically impossible to save it. Be prepared to replace the motherboard, power supply, CPU and other troublesome hardware.
buckle motherboard battery:
Each motherboard has a battery, which is used to record the BIOS. The buckle battery can clear the BIOS settings, which is equivalent to clearing the motherboard settings, and restore all the functions of overclocking to the default. This is also a good way to solve the problem that the computer cannot be turned on.
battery blocking method YYDS
power supply cable is plugged in:
If someone installs the computer and the computer cannot light up normally, or if there are some strange prompts that the computer cannot enter the system normally, at this time I will ask him to check the various power supply cables of the computer first, especially the graphics card power supply, and often forget to install it. This is similar to the fact that the front monitor switch is not turned on, but it is also one of the common reasons why the computer cannot be turned on if it fails to turn on.
