The computer case won t boot, but the fan still spins, is there any other reason besides the memory

Yes, hard disks, motherboards, and power supplies are all possible.

This is a typical memory that is not plugged in properly, or even caused by a short circuit.

1. If the memory is not plugged in properly, it is plugged in half, or obliquely, the computer will automatically shut down when it detects an error when it is turned on, 2. The fan will stop when it turns around, that is, when it is just powered on, the computer will automatically power off and stop.

3. Unplug the memory and plug it in carefully. It's good to see the gold finger inserted evenly and then turn it on.

4. This will also happen if some memory and motherboard have serious compatibility problems.

If you can't turn on the machine, it may be that the memory module is not plugged in properly, or the gold finger of the memory module is dirty. You can take out the memory module and use the eraser to erase the gold finger. Wipe both sides, just put it on after wiping.

Whether a single memory is normal, and adding an abnormal memory may be incompatible.

There are generally several possibilities for a computer to fail to turn on:

1.If the computer memory module is broken, or it is not plugged in properly, you can remove it and clean it up, clean the dust from the computer, and plug it back in to try again.

2.Whether the connection and wiring in the computer are loose, not plugged in properly, or have been aged.

3.The plastic socket that holds the CPU in place breaks, causing the CPU to break.

4.The computer system is damaged and cannot boot normally.

You can try it according to the method on Sun Peiji, it should be possible.

If the computer wants to boot up, you need to have a motherboard, memory, limb, CPU, power supply, if you don't have memory, it is also a little bit of a delay in moving the limbs, you can give the motherboard a charge, plug the memory back and try again, if it still doesn't work, you need to replace the motherboard to test it.

1.Unplug the data cable connected to the monitor and the console, and turn on the power switch of the monitor separately. Generally, if the display is normal, it will display the manufacturer's information of the display or a prompt that the monitor is not connected, if it can be displayed normally, it indicates that the display is unlikely to be damaged.

2.Check that the exposure is good. Check whether the contact between the graphics card and the monitor is good, and whether the contact between the graphics card and the motherboard IO slot is good, and if necessary, remove it and reinstall it again to ensure that it is installed in place and in good contact.

3.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.

4.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.

This fault phenomenon is generally a problem with the motherboard, it is recommended that you send it for repair, try not to move to avoid the expansion of the fault.

Isn't it, it can't be started and it starts repeatedly.
