As soon as our washing machine is turned on, the sound of E4 Didi appears.

What's going on?

Let's help you find out what the problem is.

E4 error** indicates that the washing machine's destructive drain pump is clogged or damaged. Check whether the drain pipe of the washing machine is blocked, and if so, clean up the blockage; If not, check whether the drain pump of the washing machine is damaged, if it is damaged, you need to replace the drain pump with a new one.

Good. You go to check the check.

At the beginning, it should be a problem of heat dissipation, the fan can't rotate, and the radiator doesn't touch the CPU or something;

In the latter case, the memory problem alarm is a long tone, and the continuous short tone is a problem with the graphics card.

Get the motherboard down! There may be foreign objects between the motherboard and the chassis that may cause power connection.

Your motherboard may not work.

Continuous ringing? The motherboard is broken.

As soon as the computer is turned on, it buzzes, share a little trick of yours, and easily solve the problem after reading it.

Why is there no sound? Audio? There are several possibilities: 1. The sound on the computer is turned off and muted, 2. The audio switch is not turned on.

3. The speaker is turned off and muted.

4. The cable connected to the host is not plugged in or not plugged in correctly.

5. The headphones are plugged into the stereo.

6. The audio is broken.

If it is a laptop, please refer to Article 1.

The sound card driver is not installed.

Whether the sound is muted or the volume is turned down minimum.

Whether the headphones or speakers are working properly.

What about memory problems,Get the memory down and wipe the gold finger with an eraser.,If it's useless, try to change the memory.,If it's still useless,,It's a problem with the plug of the fan power supply!

It may be that the CPU has made an error, you have to check the interface of the CPU, and it is best to check the accessories with the elimination method.

On the BIOS settings page, the system disk cannot be found.

LZ can detach the memory module and clean the gold bar with an eraser. But this is usually caused by software conflicts. It is generally difficult to find the cause. lz, if it's convenient, it's better to reinstall the system, otherwise it's quite troublesome.

You can take a look at the content of this page. Hope that helps.

Poisoned, look up this process.

The reasons and how to deal with the blue screen that cause your computer to always be blue are as follows:

First: If your computer often has a blue screen, whether you reinstall the system, or later reinstall the system, or the blue screen still appears, it means that the hardware is causing the problem. The one that directly affects the hardware of a computer is the memory module or graphics card.

The cause of the problem is the blue screen phenomenon caused by the oxidation of the gold finger of the memory module or graphics card or the poor contact of the slot. Solution: You can turn off the power first, open the computer case, dial out the memory module, use the eraser to wipe the part of the gold finger (that is, the place where there is a copper sheet) back and forth a few times, and then insert a memory slot back, and you're good to go.

If this is still a blue screen, you have to check the graphics card, explain that it is a problem with the graphics card, and also use the same method as above to do it, and you can do it. Generally, 80% of computers can solve the problem.

The second type: is the hard disk has a bad sector, when the computer reads the bad sector, it is stuck, the background is still running, the CPU occupancy is immediately very high, and then the blue screen, processing method: under normal circumstances, it is repaired with HDD, if it can't be repaired, which can only change the hard disk.

The third way: that is, the video memory chip of the video memory and graphics card appears virtual soldering, and the blue screen will continue to appear, the method is to add solder to the video memory.

Fourth: the computer is poisoned, causing the memory to enter the virus, destroying the operating system, causing the system to be unable to boot, it has been a blue screen, can only reinstall the system, or press f8 to boot up, enter safe mode, open the control panel, delete the latest updated patches and drivers.

Fifth: It's because of illegal shutdown, such as power outage, forced shutdown, or sudden crash, after turning on the machine, it will be self-checked, and it is also a blue screen, in the countdown, in general, let it read it by itself, it's fine. It may waste a little time, but it must read it by itself, because this is the process of checking the disk by the hard disk, and generally the first time it has been read, it will not appear next time.

Don't stop with ESC, or you'll have a blue screen next time, do it all over again. If you want to self-test every day, you have to start --- chkntfs t:

0", the general problem is solved.

Before doing the above, it is best to restore the BIOS of the motherboard to the factory value, or you can discharge the motherboard battery, that is, remove the battery, wait for 20 seconds and then install it back, or connect the jumper to two or three, which is conducive to eliminating strange phenomena caused by the disorder of the motherboard BIOS.

The second of these is the one with the highest probability of causing a blue screen, and if you don't try to use it, 80% of the computer will be fine.

If the above methods do not work, please reinstall the system.
