The computer can t be turned on, and there is an alarm sound all the time, and something is broken i

It's usually a memory or restore card problem.

Change the location of the memory, (wipe the gold finger of the memory).

Second, has your machine previously installed a driver for the restore card?

If you have installed it, go to the ** of the corresponding restore card, find the uninstaller, and remove the restore card driver!

I guess it's a problem with the graphics card.,Get it down and try it.。

The computer does not turn on, and the alarm is given after the start-up, and the start-up alarm is regular;

During the POST, if a fault occurs in the computer, it sometimes rings continuously, and different rings represent different error messages.

First long and then short, several long and some short; You can update the following prompts to determine the cause of the computer failure:

award bios

1 Short: The system starts normally. Shows that there is nothing wrong with the machine.

2 Short: General error, please go to CMOS Setup and reset the incorrect options.

1 long and 1 short: There is an error in the memory or motherboard. Try to change the memory, if it still doesn't work, you have to change the motherboard.

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

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

1 Long 9 Short: Motherboard Flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

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

ami bios

1 Short: The memory refresh failed. Replace the memory module.

2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to Disabled in CMOS Setup will solve the problem, but the most fundamental solution is to replace a memory.

3 Short: The basic memory check of the system fails. Change memory.

4 Short: The system clock is wrong.

5 Short: There is an error in the CPU.

6 Short: Keyboard controller error.

7 short: The real mode of the system is wrong and cannot be switched to protection mode.

8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.

9 Short: BIOS chip check and error.

1 long and 3 short: memory error. If the memory is damaged, it can be replaced.

1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

How to troubleshoot the computer boot without display. (No alarm sound).

Step 1: First of all, check whether the external wiring of the computer is connected, and plug in each cable again to see if the fault is eliminated.

Step 2: If the fault persists, then open the main chassis to check whether there is any excess metal in the chassis, or a short circuit caused by the deformation of the motherboard, and smell whether there is a burning paste in the chassis, whether there are burned chips on the motherboard, and whether the capacitors around the CPU are damaged.

Step 3: If not, then clean the dust off the motherboard and check if the computer is in good condition.

Step 4: If the fault persists, unplug the reset cable on the motherboard and connect it with other switches and indicator lights, and then use the change cone short-circuit switch to see if it can turn on.

Step 5: If you can't turn on the computer, 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 recur, indicating that the fault is caused by this device, and finally focus on checking this device.

Step 6: If the fault persists, the fault may be caused by devices such as memory, graphics card, CPU, motherboard, etc. Then, use the plug-in method, swap method and other methods to check whether the memory, graphics card, CPU and other devices are normal, and replace the damaged devices if there are damaged devices.

Step 7: If the memory, graphics card, CPU and other devices are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, connect the memory, graphics card, CPU, etc. for testing, if the computer can be displayed, then install the motherboard into the chassis for testing until the cause of the fault is found. If the fault persists, you need to return the motherboard to the manufacturer for repair.

Step 8: When the computer is turned on without display but there is an alarm sound, when the computer is booted up, the system BIOS starts to POST (power-on self-test), when it detects a fatal error in a device in the computer, it will control the speaker to send out a sound to report the error. Therefore, there may be a fault that the power is turned on without displaying an alarm sound.

If the computer is turned on and there is no alarm sound, the fault can be checked according to the meaning of the BIOS alarm sound to check the faulty device to eliminate the fault.

Discharge the BIOS battery (restore the BIOS factory defaults) It is recommended to plug and unplug the graphics card and memory, clean it up, and polish the gold finger of the graphics card and memory.
