The computer can t be turned on, the host is ticking, and the computer can t be turned on. What s go

As long as the computer is plugged in, it's right.,In addition, one end of the graphics card is to be connected to the back of the case.,And the memory module won't be interfaced.,According to the direction,From the easy to distinguish,I suspect the landlord is here to make trouble.。

The motherboard has an alarm, which means that there is hardware that cannot work normally, so the motherboard can't read the alarm. . . It may be that the hardware has some areas that are not in good contact or that there is some oxidation.

Open the main chassis to see if your CPU fan is running normally, clean up the dust on the motherboard, it is recommended to plug and unplug the graphics card and memory, clean up the hygiene, and polish the metal contact points of the graphics card and memory module.

Discharge the BIOS battery, that is, take the round coin cell battery of the motherboard down for 5 minutes (restore the BIOS factory default) IT Elite Organization 乄 IP Bugs.

If the memory is loose, turn on the host, unplug the memory, and plug it back in.

Either memory or graphics card, generally one long and two short is the graphics card, and the long sound is memory.

The sound of the alarm may be a matter of the power supply.

It's a self-test prompt sound that has passed the self-test without self-test when it is turned on, and it is a "drop".

Usually this situation is caused by hardware failure, usually called "black screen", first simple processing, there is a prompt sound, first unplug the display data cable, and the power cable (try both ends) to prevent poor contact. If there is no signal when the display is on, it can mean that the display is fault-free. If this is not possible, please follow the steps below:

1. According to the situation, most of them are caused by poor contact of memory or graphics card, open the case, reinsert and remove the memory module, and clean up the gold finger of the graphics card is the metal cable on the card, and the boot can generally be restored. Be careful, there is a anyway, don't plug it in.

2. The motherboard is unstable or dusty and will also cause a black screen, first unplug the data cable connected to the motherboard on the motherboard, turn on to see if it can pass the self-test, and completely eliminate the black screen phenomenon caused by the failure of the hard disk. If the problem is still there, the dust will be out first, then plugged in one by one, and finally tested. Eliminate dust, poor contact, and other faults.

3. If the problem still exists, you should consider the hardware damage, and the replacement method excludes memory, graphics card, power supply, motherboard, etc., good luck.

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.

Repeated short rings: Power supply issues.

No sound, no display: Power issue.

One long and eight short: the display data cable or graphics card is not in good contact.

The computer is ticking, indicating that there is a problem with the motherboard hardware, pay attention to the alarm sound, it can tell you that there is a problem.

A long and constant sound: the memory module is not plugged in tightly.

1 Short: The system starts normally.

2 Short: The CMOS setting is incorrect, and you need to reset it.

1 long and 1 short: Memory or motherboard error.

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

1 Long 3 Short: Keyboard controller error.

1 Long 9 Short: Flash RAM or EPROM error of the motherboard BIOS.

The most important feature of the microcomputer hardware structure is the bus structure, which divides the signal lines into three categories, and boils down to the data bus (date bus), address bus (address bus) and control bus (control bus). This is very suitable for the modular production of computer components, which promotes the popularization of microcomputers.

In order for the motherboard to transmit the control signal to the display and convert the digital signal into an image signal, an intermediate communication connection component needs to be installed between the motherboard and the display, which is the display card, referred to as the graphics card. Together, the graphics card and the monitor make up the display system of a computer.

The computer won't turn on, it is ticking, and you are sweating profusely. I'm going to teach you a trick and fix your computer.

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.

If the hardware is in poor contact, reinsert the memory and graphics card, and restore the BIOS (the motherboard battery is discharged for three minutes after the host is powered off).

The landlord, the biggest possibility is the contact problem of the memory module, disassemble the case, pull out the memory module, wipe the gold finger and try it, and then install it. Hope it helps!!

If there is a problem with the memory module, dial it out and wipe it clean.

The computer won't turn on, it is ticking, and you are sweating profusely. I'm going to teach you a trick and fix your computer.

It may be a hardware contact problem, open the chassis and plug the various devices back in.

Try according to these procedures, 1. Dial the hard disk, optical drive, leave the monitor, keyboard, memory plugged in, and discharge the coms, (there is a jumper on the motherboard, if not, just buckle the CMOS battery and then go up).

Power on, turn on, look at the display, if there is any response, if there is a response, it will be OK, and then put the hard disk optical drive up.

2. If not, listen to see if there is a Didi sound when booting up, yes, it is generally a memory problem, try another side.

Attached: The general computer can not start, which means that the motherboard cannot be started, there may be the following problems: memory, the graphics card is not plugged in well, there is static electricity on the motherboard, there will be an alarm if the memory is not plugged in, most of the graphics cards do not alarm, the motherboard has static electricity, the CPU fan will turn twice, and then stop).

If you often install the system, you can buy a POST card, very cheap within 10 yuan (the computer should have a PCI slot) to insert it on the PCI, according to the above data, it is very easy to know that there is a problem.

The tick sound is the sound of the motherboard reporting an error, and it depends on how long and short the sound is, so as to judge what the fault is.

Different drips represent different problems.

In the POST of the computer, if there is a failure, sometimes the bell will ring continuously, and different rings represent different error messages, according to the meaning of these information, and then make corresponding diagnosis.

It's not hard to break. The following is an example of the two more common BIOS chips (AMI BIOS and Award BIOS) to introduce the specific meaning of the common POST bell**:

award bios

1 Short: The system starts normally. 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 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.
