After the desktop computer is turned on, I only hear the main computer calling for seven or eight ti

What kind of machine is yours so messy, in this case, you have to check the memory, whether it is installed, and then the graphics card, anyway, everything has to be checked again, and if you confirm that you are completely installed, it is a compatibility problem, this problem is very annoying, your memory is not a brand, if not, pull one, to keep a brand, there are compatibility problems with different memory, and then there is the graphics card, you just try to change the graphics card, and then the sound card, In short, the so-called compatibility problem is generally a problem with the graphics card and memory, you look for it, if it is not then the problem of the motherboard, it is recommended that you replace the motherboard, if it is not good, then it is recommended to replace the power supply, if it is not good, then buy a new one, it is estimated that it will not reach this point, listen to your description should be your own machine, then look for the graphics card and memory, and the motherboard, is it very annoying, right, this compatibility problem is only so annoying that the problem is very messy, to try one by one, In the end, I may not work for some inexplicable reason, and I dizzy.

If the hardware test fails, check whether the wiring of the memory, graphics card, optical drive, hard disk, etc. is reliable, if the wiring is fine, consider the hardware damage.

You can ask about the after-sales service.

If it is within the three-guarantee period, hurry up and call someone to repair it.

It's expired.

Reasons for Dididi:

1. When the computer is turned on, the buzzer sounds and the motherboard alarms, indicating that the hardware is faulty.

2. The quality of the motherboard is not very good, and the contact between the motherboard and a certain plug-in is poor.

Reasons for the black screen of the monitor:

1. Hardware failure.

2. Software conflicts.

Solution:

1. Black screen:

1. Check whether there is a problem with the power terminal board, remove the relevant supporting parts of the computer, and replace it with some other equipment that can be used to check whether the power terminal board is working normally.

2. Unplug all hard disks, optical drives, and floppy drives, and then restart the computer.

Two: Didi Dibu:

1 Short: The system starts up normally, which is something we can hear every day and also indicates 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: RAM or motherboard error, try to change a memory, if it still doesn't work, you have to replace the motherboard.

1 Long 2 Short: Wrong monitor or graphics card.

1 long and 3 short: Keyboard controller error, check the motherboard.

1 long 9 short: Motherboard flash ram or EPROM error, BIOS damage, try to change the block of flash ram.

Constant ringing (long sound): If the memory module is not plugged in tightly or damaged, reinsert the memory module, if it still does not work, you can only replace a memory.

Ringing: The power supply, monitor and graphics card are not properly connected, check all plugs.

Repeated short rings: Power supply issues.

No sound, no display: Power issue.

The reason why the host keeps calling when the desktop computer is turned on and how to solve it:

1. Poor contact of memory modules. Remove the memory module, use a hair dryer to clean the memory module slot, and then use an eraser to wipe all the gold fingers of the memory module, and then install the memory module correctly, and fasten the clips at both ends of the memory module to change the phenomenon of poor memory contact.

2. CPU fan. Turn on the main unit, sweep the power supply fan and CPU fan to the floating soil, check whether there is a lack of oil, and add a few drops of lubricating oil to the rotating shaft.

Prompt for boot self-test, under normal circumstances, everyone hears a "drop" sound when they turn on the computer, and the computer starts successfully, but if the host hardware fails, such as no beep, the computer does not respond, or there are multiple honey sounds of different lengths, then this is the host failure.

Under. 2. Generally, the start-up alarm is a hardware problem, and the most common thing is poor contact. It is recommended to dust off the computer, use an eraser to wipe the gold fingers of each board, especially the memory sticks to plug and unplug several times.

Memory module alarm.

Disassemble the device, unplug the memory module, clean the metal part, and plug it in another slot.

Hello friends, the general computer start-up makes a didi two sounds because: due to the formation of an oxide layer on the surface of the gold finger of the memory or independent graphics card, the memory and the memory slot are in poor contact, and the graphics card and the graphics card slot are in poor contact, resulting in a black screen and cannot be turned on.

Solution: You can first power off, open the compartment, dial out the memory, use the eraser against the part of the gold finger (that is, where there is a copper sheet,) wipe back and forth a few times, and then insert back into the memory slot (or insert it back into the memory slot), it's OK, if there is a separate graphics card, you can also use the same method to deal with the graphics card, and then insert it back into the graphics card slot, and finally install the machine, restart the computer and it's OK, (take the memory ** as follows:)

Open the main chassis, unplug the memory module, rub the gold finger of the memory module with the eraser, and then insert it back into the full contact socket.

Answer: Generally, the computer start-up makes a didi two sound because: due to the formation of an oxide layer on the surface of the gold finger of the memory or independent graphics card, the memory and the memory slot are in poor contact, and the graphics card and the graphics card slot are in poor contact, resulting in a black screen that cannot be turned on.

Solution: You can turn off the power first, turn on the compartment, dial out the memory, use the eraser to wipe the part of the gold finger (that is, the place where there is a copper sheet,) back and forth a few times, and then insert it back into the memory slot (or insert it back into the memory slot), it's OK, if there is a separate graphics card, you can also use the same method to deal with the graphics card, and then insert it back into the graphics card slot, and finally install the machine, restart the computer and it's OK. If it still doesn't work, feel free to send me a private message.

Hope it helps.

Plugging and unplugging the memory module and wiping the gold finger does not become a memory break.
