Boot motherboard alarm Lasts short Unable to enter the system Black screen 30

There should be a problem with the power supply.

Here are the various alarm sounds:

Recently, many friends and colleagues have asked me that the computer is malfunctioning, and it is the best problem to always alarm when the computer is turned on? In fact, sometimes we can preliminarily judge the problem according to the length and number of alarm sounds, and now post the meaning of the alarm sound for your reference.

The CMOS of the motherboard is generally produced by two manufacturers, Award and AMI, and the meaning of their respective alarm sounds is as follows:

award bios

1 Short: The system starts normally. There is nothing wrong with the machine.

2 Short: General error, please go to CMOS Setup and reset the incorrect options.

1 long and 1 short: There is an error with the RAM or 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 Flash RAM or EPROM error, BIOS corruption.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged.

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

Repeated, short ring: There is a problem with the power supply.

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

ami bios

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

2 Short: The memory ECC verification error is incorrect.

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.

Press del to enter the BIOS settings and try to restore the standard settings!

1. Close the program in the boot startup itemRecommended

Turn off the boot startup item,Unnecessary programs,Leave only an input method,So that when you boot up,There will not be too many programs loaded in the background,And lead to the problem of slow boot。

How to do it: Start --- run--- enter msconfig enter--- find the Start option.

<>2. Fix system vulnerabilities and patches in a timely manner

Through a housekeeper or a guard, all the patches and vulnerabilities of the system are marked to avoid system poisoning due to vulnerabilities and making the machine sluggish. At the same time, through these third-party software, a comprehensive cleaning of the system is carried out.

3. Uninstall unnecessary programs, when installing new software, install the software as much as possible in other disk letters that are not C disk, I usually install it on D disk [this is determined by personal habits, and plan a tool disk by yourself].

4. If conditions permit, you can upgrade the hard disk and memory of the machine appropriately, especially the hard disk, if it is a solid state disk, there will be a qualitative leap for the system to boot up.

When setting the boot items, pay attention to the Retain input method program to avoid the system not being able to boot normally or blue screen due to the input method being turned off.

The above is a little of my suggestion, different systems may be different in operation, if there is a problem, you can send a private message + follow, I will reply as soon as possible, I hope mine can help you.

You are an HDD. Analytics is a software issue. During the period of black screen, the system starts a lot of things, it is estimated that you have installed a lot of software or junk, it is recommended to reinstall the system. Or change the hard drive socket (motherboard location) in a different place.

There is an optical drive, it is recommended to take out the internal disc.

Let's switch to an SSD.

You have to re-update the system, and if you look for a professional, you will soon uh remove the phenomenon of this family's uh black screen. Every time the computer boots up very slowly, it always turns on the black screen after the message appears, and every time the computer boots up very slowly, it always turns on the black screen after the message appears.

Re-insert the memory module, graphics card, CPU power plug, radiator, fan, especially the memory module is in poor contact, the screen is black and alarm, if the CPU radiator and cooling fan are in poor contact, the system will detect that the temperature of the CPU is too high, and it will shut down for protection.

Hello! There may be many factors in this problem, first of all, you need to see if your self-start program is too much, which slows down the boot speed, and secondly, see if your C drive has too much software installed, resulting in too much redundancy, the space is full, you can clean it up by yourself, and then whether your C disk is an old mechanical hard disk, this impact is also quite large, you can consider replacing a new solid state drive (but this requires reinstalling the system).

Set it to fast boot in CMOS, if it doesn't work, the configuration is low, set it up first, change to a larger memory to see if it's better, and if it's slow, change to an SSD solid state drive to make a system disk!

The hard drive is aging, be ready to replace the hard drive, it is best to buy an SSD. Everything is solved, and there is a BIOS restoration.

The hard drive is new, and once it is in the system, it does not run slowly.

Brother, the computer does not turn on for a long time, and then suddenly turns on and finds that it cannot be used,.

Judging from the way you check, you should still have some basic computer knowledge.

Generally speaking, if the computer motherboard and these keyboards are bright, then the possibility of the motherboard being bad is relatively small, if the display is not lit all the time, it is recommended that you start from the monitor to check and go, you can see if there is a problem with the monitor.

First of all, you can try to charge the monitor, see if the indicator light of the monitor is on, the second is the connection cable of the display, you can change the connection cable to take a look.

Also, if the computer is turned on to alarm, you need to install speak on the motherboard to have the alarm sound.

If these troubles still can't solve the problem, then it is recommended that you try to change the motherboard, sometimes the motherboard may not be used for a long time and there will be a short circuit.

It should be a problem with the motherboard, try a different motherboard.

From your description: there is a problem with the motherboard - it may be hanging. 4 years ago, there was basically no value of maintenance (ps: because the cost and stability of the repair is not as cost-effective as changing to a new one, then of course the technology is good and the repair may cost a few dollars to get it).

First of all, check whether the connection contact of each hardware is intact, set it in the BIOS not to restart, it is really not recommended to reinstall the system!

There are several situations with only the black screen, and I don't know which one yours belongs to.

First of all, your computer can't even see the motherboard information, if you can see it, it's a system problem; If you don't see it, you should look for the problem in the following questions.

1. Memory module problem: The memory module is loose and not plugged in well or there is dust, and the memory module is damaged.

2. Graphics card problem: The graphics card is not plugged in properly or the graphics card is damaged.

Third, the capacitor problem, you can see if the capacitor on the motherboard has a burst of pulp, this situation will generally occur, if there is a damaged capacitor to replace it.

Fourth, the CPU is not plugged in or loose, I hope that the third type does not appear in this case, and if the third type appears, replace it directly.

5. The computer cannot be started normally due to partial damage to the motherboard.

The motherboard is broken, and replacing it can be solved.
