My computer sometimes shuts down automatically, and even can t turn on after that, so I ask urgently

It should be that the heat dissipation of this book is not good, install a Master Lu to see if the temperature of the CPU, motherboard, etc. is very high? If it's the reason for the high temperature, you can take the book to the after-sales service to clean it up, refuel the fan or change the fan.

Turn on the console and give it a bath with a brush.

Is the computer shut down when running a big game or program, automatically shut down, and after turning it off, it is turned on, or is it automatically shut down, but the shutdown waits for more than 20 minutes to turn on, and it can be turned on, if it is the situation I described, then your computer should be caused by the high temperature of the CPU and the motherboard. The best way to judge this is the next Super Bunny, which has the temperature of the hardware tested in it. Generally, the computer of the Taiwan test will automatically shut down when the temperature is about 70 degrees.

Workaround 1Add a fan to the case.

2.It is best to place the chassis in a ventilated place.

3.If you can't do either of the above, then you just don't run a large program or game.

Or turn on the Super Bunny, turn off the game when you see that the temperature is too high, and start the game when the temperature comes down.

It may be that the life of the computer is not long, or it may be that the system has failed and needs to be restarted. Actually, I do this on my computer a lot. Don't worry, it's not an illegal shutdown. Or open a super bunny.

The system does not start at all, you can't see the power indicator light on, and you can't hear the sound of the cooling fan. At this time, first check whether the wires are connected well, whether the power cord is loose, if not, it can be basically determined that the power supply is partially faulty.

The power indicator is on, the fan is turning, but there is no obvious system action on the display. In this case, if it is a computer that has been used for a long time, it may be caused by loose memory modules or too much dust, you can remove the memory modules, clean them up and install them, and the general problem can be solved.

The power indicator is on, and the system can be started, but the system stops during initialization, and the chirp of the horn can be heard (no**). According to the peak sound**, the location of the fault can be determined. CCID Page Award BIOS 1 Short Voice:

Indicates that the system starts up normally. Indicates that there is no problem with the machine. 2 short voices:

Indicates that the CMOS settings are incorrect, and the incorrect option is set again.

Common computer troubleshooting:

Symptom: The function key of the notebook fn suddenly fails.

First, the cause of the failure:

1. If the numeric keys of the keypad fail, it is possible that the numlock key is locked, and it can be opened by the numlock key, and this key is cyclical.

2. If you haven't cleaned it for a long time, there is too much dust, which leads to the failure of some keys. Most of this situation occurs in the mechanical keyboard, if this is the reason, then the mechanical keyboard should be opened for cleaning.

3. It may be that there is a problem with the keyboard driver, you can update the driver to give it a try.

2. Solution:

1. Restart your computer. The computer will run for a long time will cause the driver to fail, if the usual fn key is good, once in a while it fails, you can restart the computer to give it a try.

In your case, you can only find the problem from the heat!

1.If the temperature is too high, it will be cooled to a certain temperature before it can be turned on!

2.In addition to the CPU, we should also pay attention to the impact of the motherboard and other hardware, especially the graphics card and hard disk, which are the heat source of the host, which directly leads to the high temperature in the machine, so that the motherboard will automatically start the protection measures, that is, automatically restart, and in serious cases, wait for cooling!

My suggestion is to find a way to keep the temperature of the main unit too high, starting with the fan and the coating of thermally conductive silicone!

Reply; A fan? Then you have to check, usually the host is two fans, more than three, respectively in the power supply, CPU, graphics card.

Is it possible that you have set a timer to shut down the power supply and disconnect.

There is a high possibility of a power supply problem with the host. It is recommended to do the system first, and then take a look at the power supply.

The system crashed, rebooted three times to no avail, and decisively reinstalled the system.

This is caused by a problem with the fan

The computer automatically recognizes each piece of hardware, and when it finds a problem with the fan, it automatically shuts down in order to protect the CPU from being burned out, so you just need to get a new fan

The fan is not expensive, just 20-30

Blocks are good to go.

It is recommended to remove the fan, clean the thermal conductive adhesive, and put it on again.

The automatic shutdown after powering on should be caused by the CPU temperature being too high.

If you don't have thermal adhesive, take it to a computer store.

There is a layer of thermal conductive medium between the CPU cooling fan and the CPU surface, and the CPU cooler must be recoated after removing the CPU cooler and installing it. Generally silicone. The better ones are added with metal powder.

It may be that the heat dissipation is poor, the temperature is too high, and the protection causes the automatic shutdown. Maybe it's because the motherboard has been around for a long time, and the CPU and the CPU are like triangles on the face. Very vulnerable.

The circuitry there is much thinner than a hair, nanoscale. Squeezing even too hard can be problematic. It is recommended to apply silicone and try again.

If it really doesn't work, send it to a professional repair shop for testing. What's more, there are always clips that are still broken.

Hope it helps.
