The computer boot cpu fan rotates, the display has no display, the main board alarm drops, drops of the alarm

Asked by: Angela 201 views Computer March 3, 2019

The computer boot cpu fan rotates, the display has no display, the main board alarm drops, the drop of the alarm, changed the memory good thing alarm, all the lines of the motherboard rear interface are pulled out, leaving the memory and the hard disk, or the same alarm Sound, forced shutdown and then open sometimes 2 or 3 times can enter the system sometimes 7 or 8 times, the operating system can run normally after entering the system, no problem, but the system restarts and then returns to the previous alarm. Ask if the motherboard is broken?

Addition: The power is also changed, or the same result

Addition: Memory has been replaced, the golden finger is also erased by

    Look at the capacitance of the CPU next to the bump or bump damage.

    It should be a problem with memory and graphics card

    First, let me talk about it, the computer hardware failure, CPU failure, press the power button, no response, memory failure, boot CPU fan Stop for a while, or CPU fan mad, video card failure black screen, hard disk failure boot into the system

    The key to see if the motherboard has a variant and capacitors, resistors with no slurry, etc. On the top, try the last one! The graphics card should be carefully inserted. Especially for motherboards that don’t work very much, try more!

    Check the board to see if there is any burning place

    Memory The fault is broken. Pull it down and wipe the gold finger and then plug it back in.

    It is usually caused by poor memory contact. After the power is turned off, the internal access is made. After wiping the golden finger with an eraser, try it on the device.

    Answer: The memory has been replaced and the power has been replaced. The possibility of the motherboard being broken is relatively large.

    1 long 2 short: Display or display card error.
    Please refer to the following motherboard alarms for details:
    AWARD BIOS ringing sound generally means:
    1 short: The system starts normally. This is what we can hear every day, and it also shows that the machine has no problems.
    2 Short: For general errors, please go to CMOS Setup and reset the incorrect options.
    1 long 1 short: RAM or motherboard error. Try changing a memory. If it still doesn’t work, you have to replace the motherboard.
    1 long 2 short: Display or display card error.
    1 long 3 short: Keyboard controller error. Check the motherboard.
    1 long 9 short: The motherboard flash RAM or EPROM error, the BIOS is damaged. Try changing the block flash RAM.
    Continuously (long sound): The memory module is not plugged or damaged. Re-insert the memory stick. If it still doesn’t work, only replace one memory.
    Stop constantly: The power supply and monitor are not connected to the display card. Check all the plugs.
    Repeating short sounds: Power problems.
    No sound, no display: Power problem.
    The general meaning of AMI BIOS ringing is:
    1. A short sound, memory refresh failed. Memory damage is serious, I am afraid you have to replace the memory.
    2. Two short sounds, memory parity error. You can enter the CMOS settings and turn off the memory Parity parity option, which is set to Disabled. However, in general, the memory stick has parity and the parity is turned on in the CMOS settings, which is good for the stability of the microcomputer system.
    3. Three short sounds, system basic memory (1st 64Kb) check failed. Replace the memory.
    4. Four short sounds, the system clock is wrong. Repair or replace the motherboard.
    5. Five short sounds, CPU error. But it may not be all the fault of the CPU itself, or it may be a problem with the CPU socket or some other place. If the CPU is normal on other motherboards, the error is definitely the motherboard.
    6. Six short sounds, keyboard controller error. If the keyboard is not plugged in, then it is easy to install, just plug it in; if the keyboard is connected properly but there is an error, you may want to try a good keyboard; otherwise, there is a problem with the keyboard control chip or related parts.
    7. Seven short sounds, the system real mode error, can not switch to the protection mode. This is also the fault of the motherboard.
    8. Eight short sounds, memory read/write errors. The memory chip on the graphics card may be damaged. If the memory slice is pluggable, just find the bad one and replace it, otherwise the graphics card needs to be repaired or replaced.
    9. Nine short sounds, ROM BIOS check error. Try changing the good BIOS of the same type. If you prove that there is a problem with the BIOS, you can try to recover by rewriting or even hot plugging.
    10. Ten short sounds, register read/write errors. Only repair or replace the motherboard.
    11. Eleven short, cache error.
    12. If you can’t hear the bell sound, you can’t see the screen display. First of all, you should check whether the power supply is connected properly. It is easy to neglect during the maintenance. If you do not connect the power supply to the motherboard, you can start the test. Secondly, let’s see if there are fewer components, such as CPU, memory stick, etc. Again, unplug all the cards in question and try to leave only the card. Finally, find the jumper on the motherboard to clear the CMOS settings, clear the CMOS settings, and let the BIOS return to the factory state. If there is no problem with the monitor or the display card and the connection, there is no problem with the CPU and the memory. After the above steps, the microcomputer still does not display or ring when the computer is turned on, and it can only be a problem of the motherboard.

    Memory problems account for most of the reasons Do not rule out the possibility of motherboard and hard disk

    You can change the power supply and try it! Basically, the problem of power supply to the motherboard 

    Question: The same is true when the power is connected.
