The computer won t start, it s just that the fan keeps turning

Sometimes the sound of the drop is that the memory is not plugged in properly, look at the memory gold finger to see if there is any rust on it, or your memory slot is not in good contact. Test it with the replacement method, unplug all the other hardware, and leave only the memory to try it at boot. If it still can't boot, it means that there is a problem with the motherboard and memory.

Can't start normally is generally a matter of the CPU, your problem you didn't make it clear, if it's memory, unless the 2 memory models are different, for example, one plugs in DDR667, one plugs in DDR800, so it can't start normally.

Unplug your memory and graphics card. Wipe the gold finger and plug it back in.

You pull out all the hardware, discharge the motherboard, don't know if you discharge, directly remove the motherboard battery, remove the battery for about 10-20 minutes, directly on the graphics card, memory, boot to see if there is an alarm, if it is displayed normally, and then connect the hard disk.

The CPU failure rate is low, and the motherboard or graphics card is generally faulty, and the memory can be tried on other machines

My computer is also the same problem as yours, I have asked many people, some people say that it is about the power supply, and some people say that they asked me to unplug all the wires and plug them in from scratch. I've tried pulling the cord and it's still very good.

There may be a problem with the power supply of the motherboard.

Try changing the power supply.

It's just that the memory is not plugged in properly, or there is a problem with the memory slot

Whether the CPU fan is safe or not, all other plugs are plugged in again.

The computer is broken. You can get a repairman to fix it.

It is very common for the computer to fail to turn on, and it is inevitable that the computer will have some failures after a long time, which is unavoidable. And some users can hear the sound of the fan turning after the computer is turned on, but it can't be turned on, what should I do? If there is really no problem with the motherboard, you can try the following methods to introduce you to the solution that the computer fan can turn and cannot be turned on.

The first method: memory unplugging.

1. First open the computer case and find the memory module;

2. Open the live buckle before unplugging, pull out the memory module with both hands, wipe it clean, and then insert it again, and then see if it can be turned on normally.

The second method: coms the battery discharge.

1. Disassemble the chassis and find the COMS battery;

2. Press and hold the live buckle and remove the battery;

3. Connect the battery to the positive and negative poles in reverse for 30 seconds, turn it on, if it doesn't work, repeat it several times.

The second method: the motherboard is loose.

1. Use a screwdriver to loosen the screws on the motherboard a little bit, and twist the screwdriver one or two times to make it almost the same;

2. Then gently move the motherboard with your hands, and then try the second method;

3. If it doesn't work, then it is likely that there is a problem with the motherboard, and it should be sent to the factory for repair.

1.First: Check all cables, including power plugs, to make sure all devices are properly and securely connected together. Next.

2.Switch failure: When the power switch button cannot be reset due to aging, or the front panel of the chassis cannot be pressed due to deformation.

3.Memory failure: When a chip or resistor capacity of the memory fails, sometimes the host can be powered on after booting, but there is no normal start-up

Chip failure: Due to the use environment, the pins of the chip will be poorly contacted due to oxidation, which will lead to the host being powered on.

The computer doesn't turn on, but the fan keeps spinning. This problem can be solved using the method of elimination. First of all, you first unplug the power cord, then plug the memory and motherboard power cords back in, and then turn on the computer to try it.

If not, it is recommended to replace the motherboard power supply or memory, if the problem is still not solved after replacement. It's very likely that it's a motherboard issue. Then you need to change the motherboard and test it.

If you really don't turn it on, if the fan keeps turning, this should be a problem on the motherboard, and you need to reinstall the memory module to reinstall it, and reinstalling it will solve this kind of problem.

If you don't turn it on, and the fan keeps turning, then this CPU may be too high in consumption, and it will be used for a long time, and the wear and tear will be serious, and it needs to be replaced only.

If the computer can't be turned on, the screen is black, and only the power light is on, it is generally a problem with the motherboard, and you need to go to the repair shop to check it.

If the computer does not boot at all, it is possible that the motherboard is damaged. Also, What does a fan refer to a CPU fan? Or a power fan? This one is different.

If the control circuit on the motherboard is broken, please ask a professional maintenance personnel to repair it.

The computer doesn't turn on, and the fan keeps turning, or does it mean that there is a problem with the host of the computer? So, you still have to find someone who can repair your computer and help you fix it to see what the reason is.
