What can I do if I can't start because of a motherboard problem?

There are a lot of problems with the motherboard, and I'll just give you a few common questions:

The first is the boot, if the power light is not lit, the monitor black screen, the other components do not have any reaction, then the general people will immediately think of whether the power out of the problem, but in fact, the motherboard is bad will appear this situation.

In a computer, the start-up of a computer requires a start-up device, generally speaking, the device is on the motherboard, which has a main starting capacitor, if the capacitor damage, there will be nothing to respond to the situation. This capacitor is very small, but it is easy to find: Pick up the motherboard, careful observation, you will find an iron electrolytic capacitor, it is usually surrounded by a wire. With such an obvious feature, it should be easy to find.

The solution is to replace a good capacitor. This kind of problem is more common, I have two friends is because of this problem and can not start the machine, one because has been over the warranty period, but had to get to the computer city repair, that is, change the capacitor. Another Buddy is OK, anyway, the replacement period has not been, simply to find a merchant for a new motherboard back, after all, the problem is small, solve it is more troublesome.

There is also the interface problem with the motherboard. Because the motherboard to take a lot of accessories, if an interface is broken, it means that the accessories can not be used, this will not start, such as: The motherboard of the AGP slot problem, it may not be able to start. In fact, this problem is strictly not due to the inability to start, it may have been started, but can not be displayed, so finally I still put it to this aspect.

I now use the computer has such a problem, the AGP slot is very loose, the card's Gold fingers and groove contact point contact, so there is no way to show, to plug a few times, to find the right direction. There is a problem with the IDE interface so that the hard drive cannot be detected at all, let alone enter the system.

In addition, there is the problem of memory slots, if you turn on the machine, the speaker in the host "beep, beep" sound, and other components do not have any reflection, this may be the memory slot is not (of course, may be the memory is bad, but now we do not consider the memory of the problem). There are other interfaces, such as CPU interface, here I will not repeat.

The most important thing on the motherboard is the chip. General non-integrated motherboards have two chips, one is the South bridge chip, one is North Bridge chip. In the traditional sense, the main task of North Bridge is as the main interface of CPU and system Exchange, in which memory controller function is the most important. In addition, the North Bridge is also responsible for communication with the Nan Qiao.

The South Bridge features a wide variety of functions, including disk controllers, audio synthesis, Ethernet network controller, as well as our frequent contact is also necessary I/O interface (such as serial port, PS/2 port, etc.). If the North Bridge chip is broken, then the CPU and the system's main interface exchange will have problems, and then the CPU on the computer will not work. Since the central processing unit can not be used, it can be imagined, and the memory control function also lost, the computer did not have two parts of the support, where still show ah?

The bridge chip once the problem, the computer also loses the disk controller function, this and without the hard drive is no different. See how important these two chips are! If the two chips burn down, that is a fatal wound, in the computer city is no way to repair, unless sent back to the original to repair. I dormitory many computers, there is a motherboard has been such a problem, the South Bridge chip burned, the warranty period has passed, had to buy a piece. If it is the integration of the motherboard is even worse, because it has only one chip, if the problem can be worse than the general motherboard problems. So in the installation or use, we must pay attention to these details, so as not to cause unnecessary losses.

Problems with the motherboard cause different startup failures. And the structure of each motherboard is not necessarily the same, so the problem is different, there is no way to describe all the situation, I just put their own experience and experience to work together to learn from each other, if there are errors or omissions or hope that we can give suggestions, I can learn knowledge from it.
