3. Short, the system starts normally, indicating that there is no problem with the machine; 2 short, the routine is wrong, please enter CMOS Setup and reset the inaccurate options; 1 long and 1 short, there is an error in RAM or motherboard.
4. Either the motherboard is broken or the CPU is not plugged in properly. Re-plug the CPU. There is a power problem. Although the power supply is powered on, it cannot make the motherboard work normally. Try replacing the power supply. If the graphics card is loose or oxidized, the keyboard light will come on and the screen will not display.

Short: The system starts normally, indicating that there is no problem with the machine. 2 short: Common error, please enter CMOS Setup and reset the incorrect options. 1 long 1 short: RAM or motherboard error. You can try changing a memory stick. If changing the memory stick doesn't work, you can only choose to change the motherboard.
This is because the memory module is dusty. It is recommended that the user just wipe the memory module. The computer beeping sound is a computer self-test alarm. Generally, you can determine which part of the computer is faulty based on the length and interval of the sound.
The graphics card is damaged, or the graphics card power supply part of the motherboard is faulty. Generally, there is a problem with the power supply of the host computer. 1 long and 3 short beeps.
