The main computer won t turn off, the keyboard is typing, it s messy, and the motherboard is ticking

1.Turn the keyboard upside down and slap it to knock the foreign object out.

2.It may be caused by a software conflict, you can restart your computer and look again. Or press F8 to restore the normal configuration of the last time.

3.There is also an easy way to borrow someone else to plug it in and see if there is any problem, or change your keyboard to another computer to try.

Note that the keyboard should be plugged and unplugged when powered off.

You didn't make it clear, typing with the keyboard was under the system or when it didn't enter the system, are you sure that the sound is coming from the motherboard? And whether your keyboard light is on or not, you can try it with a different keyboard. If the keyboard is still like this, then the problem is with the motherboard.

According to you, the judgment is that the memory is broken.

Use the substitution method to eliminate the problem, and the judgment method:

1.Press the case on the keyboard. The light is on, indicating that the graphics card, monitor, and other hardware are faulty.

2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem.

Solution: 1. If the keyboard light is not lit, first wipe the memory module with an oak and dry skin, and check whether the gold finger of the memory module has any burnt marks. Replace the memory in the slot.

2. Check the capacitors and resistors on the motherboard to see if the capacitors are bulging, whether there is a burning smell on the motherboard, and clean up the dust on the motherboard.

3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.

4. Power supply problem, although the power supply is powered on, but the motherboard can not work normally, replace the power supply and try it. No Bi.

5. If the display card is loose or oxidized, the keyboard light will be on, the screen will not be displayed, wipe the gold finger of the graphics card with an eraser, and check whether the capacitance on the graphics card is bulging.

6. Minimize the test method, only leave the power supply, motherboard, CPU, memory, graphics card, keyboard, monitor, unplug all the wires on the rest of the motherboard, use a screw knife to short the switch pins, if normal, add the rest of the hardware, piece by piece, until the cause of the problem is found.

Alas! Wrong, will also be praised.

Summary. 1.Press the case on the keyboard. The light is on, indicating that the graphics card, monitor, and other hardware are faulty. 2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem.

The computer keyboard fails and makes a ticking sound, and the computer does not freeze.

3.To see if the power supply connected to your host is grounded, if the host is not grounded, there is a power supply on the host, it is easy to generate static electricity, the solution is to change a power supply with grounding, try, see if it can be turned on.

4.If it's not a problem with the power supply, then there is too much dust on your memory module, which will also cause it to not boot up, the specific method is to take out the memory module, wipe it with the gold finger on both sides of the memory with an eraser, and blow the dust on it with a hair dryer once, and then put it back.

Notebook W7 Ultimate.

1. It may be due to a faulty keymap. 2. You can try to reinstall your keyboard device driver to see the effect. 3. Or you can change other keyboards to connect to the computer to check whether it is normal.

The keyboard had been squeezed and all the keys had failed.

Then the most likely is that the keyboard hardware is damaged, and you can go to the repair shop to disassemble and replace the hardware device.

You've done your own thing, right? I used to be like this, just because I dismantled the host, the CPU made me crooked, and when I turned on the phone, "Didi" sounded! Later, the CPU was corrected, and it was okay, you either could have the CPU, or the hardware of the memory module or something was not plugged in!

As long as you shake it, it can be turned on, which means that the power cord of the host is loose, you take the front panel apart, and replug the jumper and power cord on the motherboard according to the original position and order, you might as well try.

Send it to a computer shop for repairs.

Hello, first of all, the current BIOS can be divided into AMI BIOS, Award BIOS, Phoenix BIOS, and the latest EFI BIOS.

One of the more mainstream is the Award BIOS, which emits a regular sound of length and shortness.

You can listen to it yourself, you say four sounds, theoretically 1 long and 3 short, if the cause of this failure is the keyboard controller error. Or there is poor hardware contact inside the whole machine.

Plug and unplug the keyboard (when the keyboard is turned off), or clean the whole keyboard again and reinstall it again.

And you said that the host will be turned on as soon as you shake it, which should be a short circuit in the power button.

Therefore, it is recommended to clean up the dust of the whole machine and reinstall the whole machine if you have the ability, which may clear your whole machine problem.

If you don't press all the dripping rings, it means that your hard disk cable is in poor contact or broken, if you want to press before ringing, you will check the hardware inside, it is best to disassemble all of them and install them seriously, in the reinstallation system, the problem still exists, it is recommended to find a professional to repair it...

The laptop won't turn on, and it rings. Most of them are memory module issues. This problem can be solved after disassembly and cleaning.

The keyboard keys are stuck so the computer makes such a sound.

Computer feigned death? Or is the line broken?

It is estimated that the memory module is loose. Or it's covered with dust. Remove the wipe and put it back on.

Hardware issues, check it out.

1 Short: The system starts normally. This is something we hear every day and it also shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS setup and reset the incorrect option.

1 Long 1 Short: There is an error with the RAM or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 Long 2 Short: Wrong monitor or graphics card.

1 Long 3 Short: Keyboard controller error. Check the motherboard.

1 Long 9 Short: Motherboard flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

Repeated short rings: Power supply issues.

No sound, no display: Power issue.

Mine is like this sometimes, you heroes help.
