There has been a lot of noise inside after turning on the machine. The status indicator does not go

The noise is caused by the resonance sound of the case caused by the aging of the fan, open the case and add some lubricating oil to the fan. This is generally caused by the resonance sound caused by your unqualified chassis being too loud.

1. The quality of the chassis is not good, it is too soft, and the deformation of the chassis causes the deformation of the motherboard. CPU fans and other plug-ins such as graphics cards are not firmly fixed and vibrate and emit sounds. Exclusion Method:

Conditionally change the chassis, or remove all accessories and clean them, and firmly attach all the screws of the motherboard. Reinstall the hardware.

2. The CPU fan has too much dust and the blades do not rotate smoothly; The CPU heatsink is not securely fixed. Remove the CPU fan and heatsink to remove dust, or replace the fan.

3. There is too much dust in the graphics card fan, and the blades vibrate. The method of clapping exclusion is the same as in point 2. Clean.

It should be noted here that whether it is a CPU or a graphics card fan, it is necessary to pay attention to its power cord or other internal wiring of the case not to touch the fan, otherwise it will make noise even if it does not break the blades.

5. The second is hard disk noise, which is a general hard disk with sound, but the severity is different. Its sound is different from the others, and it can be distinguished.

Dear Lenovo users, hello!

Hello, you can try the methods in these steps below:

4. The options that could not be selected before can be changed, you can see the "Enable Fast Start (Recommended)" option (the system is enabled by default), and we can set whether to enable or disable this function here.

Summary. If your computer turns on and the light turns off, but you can still hear the computer working, it could be one of the following situations:1

Display Issues: Check if your monitor is working properly to see if it's a problem with your monitor that is causing no images to display. You can try this by changing your monitor or connecting your computer to another monitor.

2.Graphics card issues: If your computer uses a discrete graphics card, the graphics card may not be inserted correctly or malfunctioning.

Try reinserting the graphics card, or replacing it with another one. 3.Memory issues:

This can also be caused by a memory module that is not inserted correctly or a memory module that is faulty. You can try reinserting or replacing the memory module with another one. 4.

Summary. 1. Hardware failure (such as: motherboard failure, graphics card failure, memory module failure, etc.).

2. The memory module is loose or the memory slot is oxidized.

3. Liquid feed of the main engine.

After powering on or restarting, the power indicator light is on but not displayed, but there is a long alarm, and the intermittent sound is most likely to be a component failure.

Hello. 1. Hardware failure (such as: motherboard failure, graphics card failure, memory module failure, etc.). 2. The memory module is loose or the memory slot is oxidized. 3. Liquid feed of the main engine.

Memory calculation. Is it?

Calculate. It's not because of the power supply motherboard graphics card, right?

There is a good possibility.

Which of these 4 is more likely to be?

Hardware failure.

According to the landlord, there may be many reasons:

1. The power supply voltage is too low, and the universal meter is measured in different time periods, and 220 20 is not very stable.

2. The memory module is not in good contact, and dust enters the slot. You pull out the memory module and wipe the gold finger, which you have to try.

3. Heat dissipation. (You need to monitor the temperature of your motherboard and CPU) If the CPU temperature exceeds 60, you need to reapply thermal grease.

4. I don't think the blue screen you mentioned has anything to do with your computer booting up.

5. System, if there is nothing inconvenient. The reinstallation of the system is more thorough, and the problem you mentioned is very unlikely to have a hardware failure.

If you have a tool, it is recommended to measure the voltage being used, if the voltage is lower than 220, it is recommended to use a voltage regulator.

It hasn't been turned on for more than ten days, and it's raining these days.

It may be a little wet, unplug your graphics card, deal with it in the usual way, wipe the gold finger with an eraser, etc., and then restart the computer, I have also encountered this situation, the computer is much better when it is turned on for a while.

Jet Wave Hummer hao08, the landlord's CPU and graphics card configuration are very good, why would you choose such a motherboard that does not enter the stream? To be honest, the repair rate of Jetwave motherboards is very high, and my brother has never been ......So combined with the situation analysis you gave, I seriously suspect that there is something wrong with your motherboard! You'd better borrow a motherboard from a friend that can support your configuration, and try to see if you won't have the above problems.

You can also go to the forums to see if you have experience solving similar problems.

Enthusiastic answers, the owner of the watchtower adopts!

Try plugging and unplugging the memory module again.

After unplugging the CMOS battery and discharging, wait for 10 minutes and then turn on the CMOS battery, if it still doesn't work, unplug the memory and wipe the gold finger. If it still doesn't work, just change the memory.

The voltage in your home is unstable. You can use a voltage regulator, it has nothing to do with your system.

There are too many things on the C drive, and it is recommended that you change the system.

Please check if it is due to the following reasons:

1.The hard disk or optical drive data cable is reversed;

2.The system detects that the CPU is wrong (which is more likely to occur when overclocking);

3.short circuit and poor contact caused by oblique insertion of the board;

4.The expanded memory module does not meet the motherboard requirements.

The steps to resolve the issue are as follows:

1. When the power supply system fails, first check whether the AC power supply is connected to the host.

2. After confirming that the AC power supply is connected to the host, put your ears close to the switching power supply, turn on the power switch for a short time and pay attention to listeningThe reason is that the AC power supply is abnormal or there is a short circuit in the machine, which causes the protection circuit inside the power supply to start.

3. First use the AC voltage of the multimeter AC voltage 250V file to check the AC power supply voltage connected to the power plug of the host, if the AC voltage exceeds 240V or is lower than 150V, the overvoltage and undervoltage protection circuit in the host power supply will start, stop the power supply to the equipment in the machine, please change to a stabilized power supply or UPS power supply for the host.

4. If the AC power supply voltage is normal, unplug the interface card and other equipment power cords and signal lines in the host one by one, and then power on the test machine, if the host power supply resumes work when a certain equipment is unplugged, it is the equipment that has just been unplugged is damaged or improperly installed, resulting in a short circuit, so that the short circuit protection circuit in the power supply starts and stops supplying power to the equipment in the machine.

In this case, it is recommended to change the monitor to test it. If the display can be lit, it means that there is a problem with the previous display.

One is that the computer is too hot. Second, check the power supply, computer power supply, power interface If there is no problem with the contact, it is best to try another monitor to make sure that there is no problem with the monitor.

If there is no problem with the monitor, check whether the CPU fan is running, if it is running, use a multimeter to measure whether the voltage output is normal to 12V, 15V, if not, you can change the power supply to give it a try.

If the black screen still appears, take out the components installed in the computer, leaving only the CPU, graphics card, and memory sticks, and the cause of the fault can be limited to the CPU, motherboard, and memory. Generally, if there is a fault in the memory, there should be an alarm sound. If the memory fault is ruled out, only the CPU and the motherboard are left.

Change to a normal CPU (should be compatible with the tested computer), boot the computer and re-test, if the black screen still appears, you can only change to a motherboard, and the problem should also appear on the motherboard.

A black screen may indicate a serious problem with your computer, and you may wish to eliminate it as described above when the black screen occurs. In the process of treatment, the method of exclusion and substitution should be flexibly applied, and the phenomenon that occurs in a timely manner should be excluded.

You can check the memory and use the substitution method. Then there is the button battery on the motherboard, try it!

Open the case, remove the memory, wipe the memory gold finger, and clean the motherboard's memory slots.

If that doesn't work, try a different memory slot.

Clean the dust from your CPU memory graphics card cooler to make sure you're okay.
