What is the problem that the computer has no drip sound and the monitor has no signal?

There is no drip sound in the computer, there is no signal on the display, there must be a problem with the computer hardware, it is best to use the replacement method to eliminate the problem, and the judgment method:

1. Press the upper and lower case on the keyboard. The light is on, indicating that the graphics card, monitor, and other hardware are faulty.

2. If the keyboard light does not light up, it means that it is a memory, CPU, motherboard, or power supply problem.

Solution: 1. If the keyboard light does not light up, first wipe the memory module with an eraser, and check whether the gold finger of the memory module has any burnt marks. Replace the memory in the slot.

2. Check the capacitors and resistors on the motherboard to see if the capacitors are bulging, whether there is a burning smell on the motherboard, and clean up the dust on the motherboard.

3. Remove the CPU fan, power on and turn on, test whether the CPU has a temperature change by hand, if not, the CPU is not working, either the motherboard is broken, or the CPU is not plugged in properly, and the CPU is re-plugged.

4. Power supply problem, although the power supply is powered on, but the motherboard can not work normally, replace the power supply and try it.

5. If the display card is loose or oxidized, the keyboard light will be on, the screen will not be displayed, wipe the gold finger of the graphics card with an eraser, and check whether the capacitance on the graphics card is bulging.

6. Minimize the test method, only leave the power supply, motherboard, CPU, memory, graphics card, keyboard, monitor, unplug all the wires on the rest of the motherboard, use a screw knife to short the switch pins, if normal, add the rest of the hardware, piece by piece, until the cause of the problem is found.

If the computer does not make a tick sound, then it proves that the boot is not normal, the first thing to check the CPU is, there is a very high possibility that the CPU is not powered or the CPU is broken.

To check step by step, first see if the fan rotates, if not, first consider the power supply.

You can unplug the memory and turn it on to see if there is an alarm.

In general, there is no alarm when dialing the memory module on the motherboard, which means that there is no self-check to the memory at all, and it can only be that there is a problem with the CPU or motherboard. You can only replace this with the same accessory you use.

Hope it helps.

Check the power supply, see if the fan is rotating, if it doesn't move, the power supply is problematic, replace the power supply, check the memory and graphics card if the power supply is moving, if there is no problem, it is estimated that the motherboard is problematic, and it is sent for repair.

If there is no sound at all, it is likely to be a problem with the motherboard, such as whether there is a burst capacitor or something, but you can try to see if it is a problem of poor contact? It is to remove the memory and graphics card, wipe off the gold finger, and plug it back in.

Unplug all the wires behind the host, press the power button a few more times, then plug the power cord in and unplug it again, and press the power button a few more times.

Check to see if the memory and discrete graphics card are loose. There is also whether the gold finger is oxidized. If there is oxidized dust, use a rubber sassafras to cut it.

Indicate that the machine has not started, plug and unplug the memory sticks to try it, if it doesn't work, check whether the power supply is normal

In the case of ensuring that the monitor is in good condition and the heat dissipation of the host unit is normal, please check the memory module! 70% of the causes.

You can try to put the graphics card and memory, remove the ash and install it. It should be fine.

Generally, the memory is dirty, so take it off and wipe it and put it on.

The computer will not turn on with a short beep alarm sound, this is caused by too much dust in the computer, the specific solution is as follows:

1. First of all, unplug all the wiring behind the computer case

2. Then unscrew the screws that fix the chassis

3. After opening the case, you can see that there is a lot of dust inside the case

4. Use a hair dryer to blow away all the dust inside the computer, and pay attention to the corners to clean up

5. Finally, put the chassis on, and there will be no failure to turn on the machine when it is turned on again<

The reason for the memory module, take out the memory module, wipe it with an eraser or with a clean cloth, and plug it back into the computer, and you're good to go.
