When I woke up in the morning, the computer suddenly couldn t turn on

1. Half-open joke and answer well: first check the power supply to confirm and check (check the power socket of the power plug and the power socket of the computer power-on);

2. In the case of confirming that the power supply is okay, press the power button, if it does not start (that is, there is no movement directly), it means that there is a problem with the contact of the start button (that is, it is not energized) - this is solved: turn off all the power - open the chassis (if the power button can be turned on directly, only turn on the power button) - to the inner gap of the power button, drop a drop of sewing oil (one drop is enough. However, make sure that the oil has entered the gap between the keys - the purpose is to clean the stain at the conductive interface and make sure that the switch is in good contact with electricity).

Generally, if you do this, you can already turn on the computer normally as usual.

Of course, if it shuts down automatically after a while, it's a software problem (not to mention that you didn't even talk about).

3. If it still can't be turned on, open the chassis to check whether the wiring in the host is loose or falling off. If there is, plug it in (plug it in - some are invisible, so unplug them all; Also clean up the inside of the case) - yes.

4. If there is still a problem, then it is directly a computer quality problem - only buy it for 10 days, find it for exchange! ~~

Not being able to turn on the machine is generally a few phenomena.

First, there is no response when you press the power button - check the external power supply first, and then see if the motherboard is powered on, there will be LED lights on the motherboard. Second, the motherboard does not turn on when powered on - it is generally a problem of insufficient power supply and switching circuits. If possible, use the meter to measure.

Third, there is no signal from the fan to the display, and there is no alarm from the host, which is mostly a memory problem, followed by the graphics card, and there are very few problems with the graphics card. If there is a problem with the graphics card, the alarm will be called.

Fourth, the above three are fine, and the display screen has a small dot that keeps beating Not only the system, but the computer does not recognize the system files. It is usually a system damage or a faulty hard disk data cable.

Please compare it based on the above. You'd better be able to describe the problem in more detail. This gives you more specificity in solving the puzzle.

Can't find boot device anymore, boot issues or hard drive issues

Get up gas, if you have a desktop, you unplug the power and press the power button a few times to restart it after connecting the power supply.

Force shutdown and restart.

Summary. Hello, dear. The computer keeps starting in a loop, and there are several reasons why it can't be turned on:

1. Incompatible drivers can also lead to restart, and you need to restore the system or reinstall the system. 2. If the CPU or other hardware temperature is too high, you need to power off the computer and restart it after the temperature of the host drops.

The computer can't be turned on in the morning, but once it is turned on, it can always be turned on.

Hello, dear. The computer has been starting in a loop, and there are several reasons why it can't be turned on: 1. Incompatible drivers can also lead to restart, and you need to restore the system or reinstall the system.

2. If the CPU or other hardware temperature is too high, you need to power off the computer and restart it after the temperature of the host drops.

Can you tell us more about that?

There are many, many reasons why the computer can't be turned on, and it is impossible for the author to rack his brains to write them all, so today I will explain the two most common situations.

If it is still in normal use the day before, and suddenly can't turn on the next day, it is likely that static electricity has accumulated on the memory, generally this situation is common in the environment where the circuit is not grounded at home, at this time, you can choose to open the chassis, unplug the memory and gently wipe it with your fingers, and then insert the memory again, and turn it on again to see if the problem is solved.

Memory. If the computer that has not been used for a long time cannot be turned on, and it is determined that it can be used normally before, it is very likely that there is dust inside and absorbs the water vapor in the air, and it is short-circuited.

Blower cleaning method.

It should be noted that do not use too much force, and do not use a heat gun or hair dryer, as hot air can easily damage electronic components. In addition, if the computer has been restricted for a long time and has not been used, it is best to clean up the dust before powering on to avoid damage caused by short circuit.

The computer suddenly can't turn on, it is possible that the contact is loose, check it yourself, and if it doesn't work, you have to take it for repair.

What should I do if my desktop suddenly won't turn on?

See if the power supply is connected well, whether the power cord is not in good contact, if all the lines are good, then take off the graphics card and memory and wipe it on the installation to try, if it still doesn't work, go to the maintenance point to check if there is a problem with the motherboard.

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.
