How did you solve the problem that your computer won t turn on? Is it complicated?

Check the reasons below:

1. First: Check all cables (including power plugs) to make sure all devices are connected together correctly and tightly.

2. Next, check if the power is turned on. Listen to the sound of the power supply fan to see if the hard drive is working properly. If you don't hear anything, you may need to replace the power supply unit.

3. If the power supply is normal, but the screen is still dark, try to connect another monitor to the computer (you can borrow one if necessary) to make sure that it is not a problem with the monitor. If the monitor is working fine, change the **connection cable and see, still no image? If the hard drive is working properly at this point, it is very likely that the graphics card has failed.

You want to replace the motherboard with a new one. 4. If your monitor is working fine, but the hard drive doesn't boot up and the display doesn't have any images (or you can see the images but the computer can't boot with the self-test), consider setting the CMOS againTurn off the computer, unplug the power supply, and remove the battery from the motherboard by wearing anti-static protective gloves, etc.

Then wait about five minutes to consult your PC's user manual or visit the manufacturer's ** for information on how to reset the CMOS settings. Restart your computer after the setup is successful and see if the problem is solved.

It depends on whether there is something wrong with your computer, the hardware is broken, or the software is broken. The hardware is troublesome, you need to go to the maintenance point to get it, the software is broken, you have to learn to use the boot disk, or reinstall the system, the complexity is not complicated and varies from person to person, it is very simple to understand, and it is difficult to explain if you don't understand.

You can turn it on in safe mode to see what the problem is. If the safe mode cannot be solved, it can only be sent for repair.

The computer can't boot normally, first of all, check whether the computer port has a USB flash drive or mobile hard disk or something, under normal circumstances, the USB flash drive has a virus or is not plugged in well will affect the computer boot operation, we can pull out the USB flash drive and reboot it. If you can't check the abnormality, you should reinstall the system and turn it on.

Try turning it on directly on the motherboard (where the power button connects). If it can be turned on normally, replace the boot touch switch.

If you can't, repair the motherboard (50-80 yuan).

The switch button is broken, and when the power is on and it doesn't turn on automatically, you try to press and hold the switch for a second and then let go.

The sound of the drop is not your speaker,It's the equipment on board,Generally, after the host successfully loads the hardware,There will be a drop of sound to indicate that the system is up normally。 The situation you mentioned is personally thought to be caused by poor contact or incompatibility in the hardware aspect, and it is impossible to diagnose it because your statement is not very detailed. So I'm attaching you a table for you to check for yourself.

Generally, the host is dusted, and then the memory (or graphics card, the general graphics card will not have problems. The gold finger (that is, the yellow row of metal pieces below) is wiped clean and reinserted! ~

1 Short: The system starts normally. Shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS installation and re-set the incorrect options.

1 long and 1 short: There is an error in the memory or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 long and 9 short: The motherboard BIOS chip is wrong, and the BIOS is damaged. Try a different BIOS chip.

Long Ring: The memory module is not plugged in tightly or is damaged. Reinsert the memory module, or replace the memory.

ami bios

1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. In CMOS settings, set the memory options for ECC check above to disabled.

You can solve it if you use it, but the most fundamental solution is to replace a piece of memory.

3 Short: The basic memory check of the system fails. Change memory.

4 Short: The system clock is wrong.

5 Short: There is an error in the CPU.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: Video memory error. If there is a problem with the video memory, try changing the graphics card.

9 Short: BIOS chip detection error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: Displays a detection error. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

There is a problem with the hardware and it needs to be repaired.

Either there is something wrong with the hardware of the computer, you can find the repairer of the computer to see that, or it is a bolt problem, or you accidentally pressed the wrong thing [did you press the sleep button in the upper right corner].
