My computer has a ticking sound when it starts up, and the keyboard and mouse don t light up

There are many kinds of dripping sounds.

Award BIOS Alarm Tone:

1 Short: The system starts normally. There is nothing wrong with that.

2 Short: General error, please go to CMOS Setup and reset the incorrect options.

1 long and 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.

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

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 Long 9 Short: Motherboard Flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. If it still doesn't work, you can only replace a memory module.

Repeated, short ring: There is a problem with the power supply.

No sound and no display: There is a problem with the power supply.

Alarm tone for AMI BIOS**:

1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to Disabled in CMOS Setup will solve the problem, but the most fundamental solution is to replace a memory.

3. Short: The basic memory of the system (the first 64KB) failed to be checked. Change memory.

4 Short: The system clock is wrong.

5 Short: Processor (CPU) error.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: ROM BIOS check and error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

The alarm sound can be different for different motherboard manufacturers.

It may be that the hardware plug-in is loose, and it is very likely that the keyboard and mouse interface is plugged in backwards or loose.

My family's computer industry always has this problem, I just unplug the memory every time and change it to another slot.

Dizzy! On the 2nd floor, which of you has static electricity in the memory! I don't know if the landlord is not! You take the eraser to erase the metal part of the memory! In a change of slot!

1.Press the 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 problem with the mother-in-law's mega memory, CPU, motherboard, or power supply. Settlement of the Lease Law:

If the keyboard light is not lit, 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. Check the capacitors and resistors on the motherboard to see if the capacitors have a nuclear bulge, whether there is a burnt smell on the motherboard, and clean up the dust on the motherboard.

Summary. Hello, happy to answer your questions<>

Your question is: what should I do if the computer does not turn on and the keyboard does not light up, after inquiry, I will provide you with the answer: Hello, dear, in this case, first of all, the dust on the motherboard and fan in the chassis should be cleaned up, and it is best to blow the fan with a cold air (one is to blow the dust, the other is to blow off the moisture), carefully check whether the dust accumulates in each slot, and then re-plug the CPU, fan, memory module, graphics card, and hard disk socket firmly, Press the power button several times without power after unplugging, Finally, plug in the power cord again and turn it on, if it still doesn't work, it should be a hardware problem, and then check the problem one by one.

Hope it helps<>

What should I do if the computer does not turn on and the keyboard does not light up?

Hello, happy to answer your questions<>

Kaihui with a heart],Your question is:What should I do if the computer is not turned on and the keyboard is not lit,After inquiry, I provide you with the answer:Kiss hello Zhinian,In this case,First of all, the dust on the motherboard and fan in the chassis should be cleaned up,It is best to blow the fan with cold air (one is to blow the dust,The other is to blow the moisture off),Carefully check whether the dust accumulates in each slot,Then reinsert the CPU、Fan、Memory module、Graphics card、Hard disk socket re-inserted firmly, After the power cord is unplugged, press the power button several times without power, and finally plug the power cord back in to turn it on, if it still doesn't work, it should be a hardware problem, and then check the problem one by one.

Hope it helps<>

If the fault persists, then open the main chassis to check whether there is any excess metal in the chassis, or a short circuit caused by the deformation of the motherboard, and smell whether there is a burning paste in the chassis, whether there are burned chips on the motherboard, and whether the capacitors around the CPU are damaged. Step 3: If not, then clean the dust off the motherboard and check if the computer is in good condition.

Step 4: If the fault persists, unplug the reset cable and other switches and indicator wires on the motherboard, and then use the reed cone short-circuit switch to see if it can be turned on. Step 5:

If it can't be turned on, the scrambling trace uses the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device. Step 6:

If the fault persists, the fault may be caused by devices such as memory, graphics card, CPU, and motherboard. Then, use the plug-in method, swap method and other methods to check whether the memory, graphics card, CPU and other devices are normal, and replace the damaged devices if there are damaged devices. Step 7:

If the memory, graphics card, CPU and other equipment are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, connect the memory, graphics card, CPU, etc. for testing, if the computer can be displayed, then install the motherboard into the chassis for testing until the cause of the fault is found. If the fault persists, you need to return the motherboard to the manufacturer for repair.

The laptop has a dripping sound when it is turned on, the screen lights up, and the keyboard light doesn't turn on.

The laptop boot has a dripping sound, the screen lights up, and the keyboard light is not lit, as follows: Hello 1, if there is an alarm sound when the electric front is turned on, there must be a problem with the computer hardware, and then look at whether the light of the keyboard is on, you can press the upper and lower case keys on the keyboard. The light is on, indicating that there is a problem with the graphics card or other hardware is faulty. 2. If the keyboard light does not light up, it may be a problem with the memory, CPU and motherboard.

Suggested treatment: 1. If the keyboard light is not on, it is recommended to use an eraser to wipe the memory module, and then check whether the gold finger of the memory module has any burn marks. It is recommended to replace the lower slot.

2. It is recommended to check the capacitors and resistors on the motherboard, see if the capacitors are bulging, whether there is any burning smell on the motherboard, etc., and then clean up the dust on the motherboard. 3. You can remove the CPU fan, turn on the power again, and test whether the CPU has a temperature change by hand, then the CPU is not working, or because the motherboard is broken, maybe the CPU is not plugged in well, it is recommended to re-plug it for the power supply problem, even if the power supply is powered on, but it can not let the motherboard work normally, it is recommended to replace the power supply to try. 5. If the display is loose or oxidized, the keyboard light will be on.

If the screen does not display, wipe the gold finger of the graphics card with an eraser, and then check whether the capacitors on the graphics card are bulging.

Simply put, it's memory or graphics card!

If your graphics card is integrated, then there is only memory, just plug the memory or graphics card into it, it is best to wash the gold finger with alcohol, and then go up, 90% will be fine.

First of all, unplug the monitor connection cable, turn on the power of the monitor, and see if the indicator light turns from green to yellow, and whether there is a prompt on the same screen: no signal input and other prompts, if there is, it means that the monitor is good. Then check the host to see if it is a graphics card problem, if there is a discrete graphics card, reinsert and dial it again.

If you don't have a separate graphics card, you can plug in the memory and try it.

If the graphics card is faulty, put it down and plug it back in.

Motherboard problems or poor contact of graphics cards and other equipment Didi's should be the alarm sound of the hard disk.
