The computer can t be turned on after the ash is cleared, and the CPU fan turns without a dripping s

The memory and graphics card are unplugged to see if the alarm should not be a problem.

It's just to pull out the memory and graphics card to see if there is any dripping sound.

Are you sure the CPU is installed? Is it a pin or a copper piece to see if there is a broken foot or a crooked needle, so let's tell you that if you don't insert the memory and graphics card and don't have an alarm, it's either the CPU or the motherboard I guess your CPU didn't do a good job.

Remove the graphics card and wipe it Don't just wipe the memory module, it is recommended not to install the memory and the graphics card to boot it first, see what the reaction is, listen to the alarm sound, then install the memory module, and then install the graphics card, the alarm sound is different. The possibility of poor contact of the graphics card is greater. The gold finger of the graphics card is first erased, and then wiped with a brand new RMB of 100 yuan, and the one below 50 yuan is not good, and that thing is open to money.

The CPU must be installed, and the CPU radiator can be installed without silicone and then installed after booting. Buckle 41506534

Let's reassemble it with a professional.

Try jumping the motherboard jumper.

The computer can't turn on after the dust is cleaned, and the fan is loud The first few times I wiped the memory with an eraser, and it turned on, and this time I wiped it and couldn't turn it on.

Hello dear! According to your description, the detachable infiltration reeds are the situation where the position of the fan connection line is not noticed during the cleaning process, resulting in poor connection and a loud fan noise. Also, the memory module wipe may just be a temporary fix to the problem and not the root cause.

It is recommended that you check whether the fan cable is secure, and if it is loose, it should be re-plugged. If the issue persists, you can try reinstalling the memory module to make sure the slot is clean and dust-free. In addition, it is also possible to check whether the power supply is normal and whether it needs to be replaced.

Extraneous expansion: After the computer is used for a period of time, a lot of dust and dirt will accumulate, which will affect the heat dissipation and running speed, so it is recommended to clean the computer regularly. When cleaning, it is necessary to pay attention to the state of computer switching, and use professional cleaning tools and methods to avoid unnecessary damage.

At the same time, you should also pay attention to keep the surrounding environment of the computer clean and dry to avoid dust and moisture affecting the computer.

What do you mean by ash? Dismantled the case to clean up the dust? Which fan is the fan talking about?

CPU fans, some notebooks are intelligent temperature control, and the temperature will not rotate if it is not at a certain height. Is the current situation that the fan will not turn on and still be able to boot normally and enter the system? If Master Lu prompts that the temperature of the graphics card is too high, then please check if you broke the graphics card fan when you disassemble the machine?

Or you have accidentally loosened the power cable.

Laptop fan, CPU above 50 degrees temperature, the fan turns, if there is a problem with the fan, it is generally about 100-300 to replace a new one!

Go fix it. Do not turn on the machine before repairing. Otherwise, the machine will burn out.

Take it apart and clear it again, and it might be fine. I guess you ran into something and got stuck.

Let's go to a specialty store and fix it.

。。Is this the graphics card so that you broke it Go directly to the repair station The small fan is guaranteed for one year This is guaranteed according to the invoice you purchased the machine.

Hello friends, after the general cleaning, the sound of the fan is very loud, which can only be turned on again, further clean the temperature control fan or add a little oil, if necessary, remove the fan and replace the fan of the same model. This will clear up the noise. If this affects the heat dissipation for a long time, it is particularly detrimental to the CPU.

There is a gap between the fan blades and the bearings, and when you clean up the dust, there is dust or "ash" stuck in it, so it is more noisy.

Or simply buy a fan blade, up to 8 pieces, usually 5 pieces. Computer consumables stores sell it, and when you buy it, bring the "corpse" over and compare it to buy.

Your previous fan was slow at first (loud sound) and then fast (low sound), so the noise was like that, and the speed of the fan was fixed after you finished cleaning the dust, and the "sound" was also fixed. Of course, whether it's slower or faster than before, you can see for yourself.

It's that the CPU heatsink is not installed properly, and it is good to reapply silicone grease and install it once.

Causes and solutions:

1. The memory module is loose or damaged.

Solution: Use an eraser to wipe the gold finger of the memory module and reinsert the memory stick; Replace the memory module.

2. Poor contact of the graphics card.

Solution: Same as memory method.

3. The main engine is short-circuited.

Workaround: Clean up the host and replug the wiring.

4. Motherboard BIOS problems.

The motherboard BIOS stores important hardware data, and if it fails, it can cause the computer to not boot.

Solution: Go to the motherboard BIOS settings page and restore the BIOS to the default value.

This is the reason for the memory stick, you can use the eraser to wipe the memory metal strip to deal with it!

Your computer's power cord is plugged in, and it makes you dizzy.

There are two reasons why the computer fan does not rotate, the first is power supply.

Second: the wiring of the socket should be connected.

Looking at Figure 1, the line doesn't seem to be connected.

It's simple If the plug is plugged into the motherboard's pins accurately, and the system boots up properly, then the fan is stuck or damaged and must be replaced.

You didn't plug in this radiator head.
