My computer can t be turned on, and it always beels when the power is turned on

The long sound is a problem with the memory module, loose or broken, it is recommended to check it!

The memory module is loose or broken, and the CPU fan.

The memory module is not plugged in tightly or damaged.

The solution to the problem of not being able to turn on the computer when it starts up is as follows:

1. First of all, we conduct a comprehensive check on the connection between the computer display Biqiao Kai device and the host, and plug each connection again to see if there is a connection problem.

2. If the fault still exists, then we need to open the chassis to see if the chassis contains metals and other substances, causing a short circuit in the computer host circuit, and then we smell the computer to see if there is a burning smell, and see if there are damaged components around the motherboard and around the CPU.

3. After checking the whole chassis, the chassis is not abnormal, then we will dust the chassis.

4. If it can't be turned on, then use 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 reappear, indicating that the fault is caused by this device, and finally check the device at the midpoint.

The desktop computer has a long beep when it boots up, and it can't be turned on because the hardware that it should have was not detected during the POST test. There are two main possibilities: the memory and the graphics card are not bad, the contact is bad, or the memory and the graphics card are broken.

The computer starts up with a long beep, and it can't be turned onSolution:

1. If the graphics card is not plugged in, wipe the gold finger with an eraser and plug in the graphics card. Be careful not to let the rear end of the graphics card press down, otherwise it will make a bad contact.

2. The memory is not plugged in. Wipe the gold finger with an eraser, carefully load the memory and buckle it on.

3. Memory incompatibility. If you have two memories, try switching to a single-channel or single-memory start. If there is one, we recommend that you replace the memory.

The reason for the long beeping alarm when the computer boots up is a memory problem, here's how to solve it:

1. First of all, clean up the memory module, and use your fingers to pull the card of the memory slot to both sides to remove the memory module; Erase with a rubber band; Then aim the memory module with the bayonet, point at both ends of the memory module, and press it a little harder; After installing the memory module, turn it on and see if it can start the computer. Most of the problems of long computer beeping can be solved in this way.

2. If the first step is still invalid, then replace the memory slot first, see if the slot file is bad, and then reinstall the memory module.

3. If the problem of Changming cannot be solved, it means that the memory module has been damaged and needs to be replaced.

1 Short: The system starts normally.

2 Short: Regular error. Workaround: Reset the BIOS.

1 long and 1 short: There is an error with the RAM or motherboard.

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

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

1 Long 9 Short: Motherboard Flash RAM or EPROM error, BIOS corruption.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged.

Keeps ringing: The power supply and monitor are not properly connected to the graphics card.

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

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

Generally speaking,Changming is a memory module failure,I wiped it before and it can be used,Poor quality memory will naturally not work after a long time,I don't have to say,Change the memory module。

If it is a long beep constantly ("Drops"constantly), that's a memory problem, you have to unplug it and reinsert it, or change the slot;

If it's one long beep and two short beeps ("Drip drip"In this way), it is a problem with the graphics card, and it is also necessary to unplug and reinsert it, or change the slot;

If it is a regular short beep ("Drip, drip, drip, drip"It is called regularly), that is the CPU has poor heat dissipation, pay attention to heat dissipation, you can open the case and blow it with a fan, or change an effective fan, or turn on the air conditioner indoors, or don't run programs that occupy too much CPU.

1 Short Sound - Normal.

2. Short Voice - CMOS setting is incorrect.

1 Long Tone 1 Short Sound - Memory motherboard error.

1 long 2 short - the graphics card display is wrong.

1 long 3 short - keyboard error.

1 long 9 short - BIOS storage error.

Continuous beep - the graphics card is not plugged in.

Continuous rush sound - power supply problem.
