How do I get a black screen on my computer?

This is not easy to do, and the different sounds of the computer mean different things.

My computer has also thought about it, and I am in a hurry, I understand. Let's see for yourself.

The computer is turned on with a black screen and an alarm sound.

The computer is turned on with a black screen and an alarm sound (Award BIOS).

Fault phenomenon: Award BIOS motherboard, black screen at boot with alarm sound.

Analysis and processing: Faults can be judged by alarm sounds:

1 Short: The system starts normally. Congratulations on your machine without any problems.

2 Short: General error, please go to CMOSsetup to reset the incorrect option.

1 long and 1 short: There is an error with the RAM or motherboard. Try a different memory module, if it still doesn't work, you have to replace 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 9 Short: Motherboard Hash RAM or Eprom error, BIOS corruption. Try changing the block hash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or is 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 ring: There is a problem with the power supply.

No sound and no display: There is a problem with the power supply.

The computer is turned on with a black screen and an alarm sound (AMI BIOS).

Fault phenomenon: AMI BIOS motherboard, black screen at boot with alarm sound.

Analysis and processing: Faults can be judged by alarm sounds:

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

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to Disabled in CMOS Setup will solve the problem, but the most fundamental solution is to replace a memory.

3. Short: The basic memory of the system (the first 64KB) failed to be checked. Change memory.

4 Short: The system clock is wrong.

5 Short: Processor (CPU) error.

6 Short: Keyboard controller error.

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

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: ROM BIOS check and error.

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

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

How do you know that the host is good, is there a start**? If there is a sound, the monitor cable is not plugged in properly or there is a problem with the graphics card, monitor, or cable.

On there are instructions on which keys you press.

There are many ways to black screen, you take a ** after the black screen lasts, some black screens have words, and some are completely black.

The computer screen is completely black, press the power button after turning on, unless the computer screen is completely wordless, or the screen lights up and says no signal, this is the hardware failure of the host. If it cannot be solved by simply wiping the memory or graphics card copper feet, replugging and unplugging the hardware (excluding poor contact) and other methods, then most of the problems lie in the CPU (10%) or motherboard (70%) and other faults (20%), which need to be replaced or sent for repair.

The display is connected to the wrong interface, and there is a separate display or board display to troubleshoot as appropriate.

There are several reasons why the computer has a semi-black screen and there are words behind the black screen, some of which are because the keyboard is not connected properly, and the system requires no keyboard to be turned on.

Some are because the motherboard CMOS battery is dead, you are asked to press F1 to skip, you can try whether it will turn on after pressing F1, if it will, it is CMOS out of power, you need to change the motherboard battery.

Another common problem is a broken hard drive, poor hard drive cable or port contact, system crash, and loss of system files. These will have a line of words above them (...)boot...

Or a cursor flashes, this is the hardware can not find the operating system, to further analyze is the hard disk is broken, poor contact, or the system files are lost, if the file is lost, find a master to make up the file or reinstall the system can be solved, if it is the internal hardware of the hard disk, most of the system can not be reinstalled, you can reinstall the system to troubleshoot.

Simple error, monitor or console power cord not plugged in? The power strip is not on? Broken power strips? Broken power cord? Broken power supply?

Specific analysis of specific problems, it is best to bring a picture, otherwise, there are 100 possibilities for a black screen, as a familiar hand, you can't judge your specific problem, please describe the details of the fault in the above picture or more.

Shutting down your computer and restarting it can sometimes fix this black screen issue.

There are many reasons for a black screen, and you'll have to figure out which one it is.

1.Virus. 2.The configuration is too low such as graphics card, memory, CPU, etc.

3.The fan problem cannot dissipate heat in time, causing the main engine to turn off.

4.Check that the monitor is properly connected to the console.

5.Check to see if there is anything wrong with your monitor.

6.There may also be plugins such as malicious plugins.

7.Is there a problem with the cable used to connect the main unit to the monitor8There is an incompatibility in the system.

For reference, I personally think that it is more likely to be a problem with the virus. It's really not okay, ask a professional to take a look.

It may be poisoned, ask a professional if needed.

Two. Check that the power cord of the monitor and the connection of the monitor are not loose.

Then whether the connector and socket are in close contact.

If the monitor keeps turning on and off.

Observe it. When the screen is black, whether the indicator light of the display is turned off, if the indicator light is also off, then it is very likely that there is a problem with the power supply of your monitor's circuit.

If the screen is black, the indicator is normal, just from green to red or yellow with no

**Lip alarm input, so the screen will automatically go black and enter sleep mode, while the indicator light of the monitor should turn red or yellow. When working normally, the indicator light that shows the brother potato device should be green.

If it can't be checked, and the problem is still not solved, send the dust cover for repair.
