What do the four lights of the MSI motherboard EZ Debug indicator mean?

I still remember the early old computers. If the computer cannot be turned on after the computer is turned on, it is judged by the beep sound to determine which hardware has the problem. Nowadays, many MSI motherboards on the market integrate the EZ Debug indicator light, which is called in the motherboard manual. “Simple debugging LED light”, compared with the motherboard diagnostic card that only displays numbers, it is more convenient to use, and it is faster to find the location of the computer failure. So what do the four lights of the MSI motherboard EZ Debug indicator mean? The following installation home will teach you how to use the EZ Debug indicator light to judge the failure of the power-on point.

What do the 4 lights of EZ Debug on the MSI motherboard mean?

The MSI motherboard EZ Debug indicators are mainly divided into four LED lamp beads, which are CPU, DRAM, VGA, and BOOT indicators. When the computer is turned on, the EZ Debug indicators will light up one by one in the order of CPU, DRAM, VGA, and BOOT. There may be a hardware failure, the official description is as follows.

The EZ Debug CPU light is on, indicating that the CPU cannot be detected or is faulty.

The EZ Debug DRAM light is on, indicating that the memory cannot be detected or is faulty.

When the EZ Debug VGA light is on, it means that the graphics card cannot be detected or is faulty.

The EZ Debug BOOT light is on, indicating that the boot device (such as a hard disk) cannot be detected or is faulty.

How to use the EZ Debug indicator to judge the failure of the power-on point?

If the EZ Debug CPU light is on, it is generally because the motherboard cannot recognize the CPU. The worst possibility is that the CPU itself is damaged, but there is also a certain possibility that the CPU power supply of the motherboard is faulty, or there is a problem with the pins of the CPU socket on the Intel motherboard. , Most AMD motherboards are because the motherboard cannot recognize the new CPU. It is recommended that if this happens, you can check that the CPU power supply is still plugged in tightly. Take out the CPU to see if there are any curved pins in the CPU slot pins of the Intel motherboard. For AMD platforms, check the CPU. Whether there is a case of bent needles.

If the EZ Debug DRAM light is on, it generally means that the motherboard cannot recognize the memory. The possibility is that the memory is broken, but it does not rule out that the memory slot is broken. Therefore, it is recommended to replace memory with a slot for testing. Root test, that is to say, if this memory fails the test and still cannot be turned on, change another memory to continue testing. It is not ruled out that there is a problem with the memory controller of the CPU.

If the EZ Debug VGA light is on, it generally means that the core display or independent graphics card cannot be recognized. The worst possibility is that the graphics card is broken. It is recommended to try to re-plug the independent graphics card to see if the independent graphics card is not inserted tightly. Check the graphics card Check whether the golden finger part is fully inserted. If the motherboard has two graphics card slots, you can try to replace the independent graphics card with another graphics card slot. What is not ruled out is that there is an independent graphics card. After the video cable of the monitor is inserted into the display interface on the motherboard, it must be inserted into the display interface of the independent graphics card. If the keyboard indicator light is on, press the NUMLK key and the indicator light will go off, and then press it again to turn it on, and the independent display is also re-plugged and made sure it is firmly inserted, then most of the graphics card is broken. If there is a nuclear display, unplug the independent display, and plug the video cable into the display interface on the motherboard to test it. If the nuclear display can light up, it can also indicate that the independent display is broken.

If the EZ Debug BOOT light is on, it means that there is a boot failure. The worst possibility is a hard disk failure. It cannot be ruled out that the system boot crashes or there is no operating system on the hard disk. If it is not bright, if it is a DP cable, you can try to replace it with an HDMI cable, and check the display and video cables.

If it can’t be solved, it is recommended to discharge the main board for a try. The method of discharging is very easy. Find the button battery on the main board, take out the button battery and leave it for about 20 seconds, then install it back, and try again.
