When the computer turns on, there is no beep or display.

What should I do if there is no beep when the computer is turned on and the monitor does not display?

The computer turns on and the screen is black but there is no beep. The reasons are: memory failure; graphics card failure; monitor failure. No sound means there is a problem with the CPU and motherboard. It is recommended to clean the dust on the motherboard. If it is in the south, please put the machine under the sun (not direct sunlight) to remove moisture.

There is no beeping sound when the computer is turned on. This means that the motherboard has not passed the self-test and cannot be started. Usually the gold finger of the memory or graphics card is oxidized, resulting in poor contact between the memory and the memory slot, and poor contact between the graphics card and the graphics card slot, resulting in the inability to boot or a black screen at boot.

Observe the indicator light on your case to see if it lights up when you turn on the computer. If it does, check your monitor's power supply (socket) and power cord (try changing them).

The computer cannot be started, the monitor has no display, and the host has no alarm sound. Description: There is no power at all. It is likely that the power cord is poorly connected to the external power supply, or there is a problem with the power socket.

After the computer is turned on, there is no self-check, no beep, no alarm, no signal on the monitor, only the fan is running...

1. The computer cannot be started, and there is no display on the monitor. The host has no alarm sound, indicating that there is no power at all. It is likely that the power cord is not connected to the external power supply, or there is a problem with the power socket.

2. When the computer is turned on, the screen is black and there is no beep. The reasons are: memory failure; graphics card failure; monitor failure.

4. Plug in the power cord tightly, check the plug on the plug board, and confirm that the plug board is powered on. Confirm that the wire from the host power supply to the plug-in board is good, then take the power supply and connect it to the 24P plug on the motherboard, short-circuit the green and any black wires. If the power fan is spinning, it means there is no problem with the power supply. If the power fan is not spinning, it means the power supply is broken. Replace it with a new one. power supply.

5. There is no self-check when turning on the computer. Generally, please check whether the graphics card and memory are dusty or loose. (Just remove the memory and graphics card and turn on the computer. Will it trigger an alarm?) If these 2 are correct, it is a motherboard problem.

6. Step 1: Check the computer's external connection cables and signal cables. After re-plugging and unplugging them in sequence, observe whether the fault is eliminated. Step 2: If the fault persists, open the chassis and observe whether the components inside the chassis are visible to the naked eye. damage, whether there are excess metal objects causing a short circuit, and whether the motherboard capacitor is exposed.

There is no beep when the computer starts up

Step 1: First check whether the external wiring of the computer is connected properly, and re-insert each connection to see if the fault is eliminated.

Normally, the desktop computer will perform a self-test when it is turned on. A short beeping sound indicates that the self-test is normal. If your desktop turns on without beeping, it may mean a hardware failure or a connection issue causing the self-test to fail. Here are some possible solutions: Check the power supply and power connections.

What to do if there is no sound when the desktop computer is turned on

Check whether the connection between the host and the speaker is loose or disconnected, whether the speaker power is turned on, and whether the speaker's volume knob is turned down to the minimum. For independent sound cards, check whether the sound card is in good contact with the motherboard slot. You can re-insert the sound card. For motherboard-integrated sound cards, check to see if they are disabled in the BIOS.

Check whether the power supply and power connection are normal. Check whether the memory module is inserted correctly or whether it is faulty. Check whether other hardware is loose or poorly connected (such as hard drive, graphics card, sound card, etc.). Try clearing the CMOS by removing the battery from the motherboard, then waiting a few minutes before plugging it back in.

Shut down the computer and restart it to add new hardware." Note that it says shut down and then restart, not restart. Generally speaking, the problem can be solved after restarting.
