MSI motherboard problem, unable to boot POST A2 in the lower right corner is stuck, high score for a

MSI motherboard cannot be turned on for self-check, the lower right corner A2 is stuck, this situation occurs because the motherboard's chip is burned out, and the motherboard chip is damaged because it is usually caused by illegal shutdown or sudden power failure, replacing the motherboard chip can solve this problem, the specific operation steps are as follows:

1. Use tweezers.

Clamp the cover plate of the chip.

2. The cover plate is clamped off.

3. Use a thermal spray gun to blow hot air along the perimeter of the chip.

Be sure to blow round and round, don't blow at a fixed point.

4. After blowing, use tweezers to clip the chip off.

5. Install the new chip.

6. The cover plate covered with the chip is completed.

You need to delete all the original partitions of your hard drive and reboot it. Then try to partition again. I am also this motherboard MSI Z77A-G45 , also with Samsung 830 128G SSD Win8 , the data disk is a Western Digital 1T blue disk.

Last week, there was also the fault you mentioned, and there were two days at the beginning when it was to boot to the A2 state to pause for 15 seconds, and the result was that after two days, the boot to A2 was stuck, and the hard disk light was always on. Remove the blue disk, and it won't get stuck under A2. Smooth access to the system.

Connect the blue disk to the GIGABYTE P45 motherboard and it boots up fine. In addition, I found a green disk to connect to the MSI motherboard, and it was fine, and it entered the system normally. It made my head big, and then after deleting all the blue disk partitions, I continued to connect to the MSI motherboard, and everything was normal, nnd.

There seems to be a BIOS setting for the SSD hard disk If you update the driver, the interface connected to the SSD disk is set to that mode, and the compatibility is better I don't remember what mode it is called for a while You look at the motherboard driver description of the official network, there should be this kind of setting, you rebuild the mechanical hard disk is not a good solution The root cause should be the compatibility of the motherboard driver.

1. Motherboard, also known as motherboard, systembourd and motherboard; It is installed in the chassis and is one of the most basic and important components of the microcomputer.

2. The motherboard is generally a rectangular circuit board, on which the main circuit system of the computer is installed, generally including BIOS chips, IO control chips, keyboard and panel control switch interfaces, indicator plugs, expansion slots, DC power supply connectors of the motherboard and plug-in cards, etc. Another feature of the motherboard is that it adopts an open structure.

3. Most of the motherboards have 6-8 expansion slots for the control card (adapter) of PC peripherals. By replacing these plug-in cards, the corresponding subsystems of the microcomputer can be partially upgraded, so that manufacturers and users have greater flexibility in configuring models.

4. In short, the motherboard plays a pivotal role in the entire microcomputer system. It can be said that the type and grade of the motherboard determine the type and grade of the entire microcomputer system, and the performance of the motherboard affects the performance of the entire microcomputer system.

The motherboard of the computer is the largest computer hardware that carries the computer memory, hard disk, CPU, graphics card in addition to the chassis, to put it bluntly, it is the circuit board, if you want to see what model your computer hard disk is, you can use the hardware detection function of the computer manager toolbox, you can query it directly.

Test the stability with the software orthos, bake it for 3 hours, and you basically passed the test.

Look at the hardware, use everest CPU-Z GPU-Z Windows optimization master.

There are system tests and system stability tests in the everest software.

Why don't you use CPU-Z GPU-Z! How easy it is to use this!

D18-D19-D20, diode, the conduction condition is positive and greater than the negative electrode, then when the negative three signals are high, the diode is cut off. Keep the positive electrode high. sys pwrgd is high.

If any one of the three signals in the negative pole of the D18-19-20 diode is low (ground), then one of the three corresponding D18-19-20 diodes will be turned on, and when the positive electrode of the diode is low, then the sys pwrgd will be low.

There is no need to make your own, the motherboard diagnostic card is less than 10 yuan a, it is through the ** display of the information when the motherboard starts the self-test, and you can buy it in places like the computer city.

Right-click on my computer properties Device Management and it will come out with a very complete information.

Different computer hardware breaks down and has different effects. Let's talk about the impact of the main hardware parts being broken.

1. If the power supply is broken, the impact is that the computer cannot be turned on and is in a state of three nos, such as no sound, no image, and no indication.

2. If the memory module is broken and occurs from time to time, the boot is normal, the use is also normal, and occasionally it will automatically shut down or restart automatically, or the blue screen, or crash; The alarm sound appears when the computer is turned on, and the computer screen does not respond. The alarm sound is generally long, dripping ......; There is no response when you press the power button, and this situation has been encountered many times, mostly due to poor contact.

3. If the motherboard is broken: stuck, black screen, no display, etc.

4. If the CPU is broken: no display, motherboard tweeting, etc.

5. If the hard disk is broken: you can't enter the system after booting the computer, and you can enter the first screen after removing the hard disk.

6. If the keyboard and mouse are broken: do not enter and cannot perform any operations.

7. If the network card is broken: you can't get on the network, you can't connect to the network, or the Internet is so slow that you can't get to the Internet.

You don't say what the interface is, generally speaking, it's no problem to fill the needle. Look at you, it will automatically power off when you turn it on, and the motherboard should not be a pin that has fallen off, or it is not a pin dropped by the general interface.

This is the plug of the front panel of the host.,If it's broken, the front panel may not be usable.,The motherboard is generally fine.。

Hello,The computer's power options system will have a default setting,You don't need to modify it if you don't understand it too well,And then about the hardware compatibility problem,This is not good,For example, if you change the memory module,Plug it in,It can be used normally,If you don't often crash blue screen,Proof is OK,Anyway,If you can't start or often crash blue screen proves incompatible,Thank you, landlord,Answered。

Dude, Zhongguancun Analog Building Forum, the answers you want have to learn by yourself, and it's true.
