The Southbridge is a chip on the motherboard that manages the computer's input and output interfaces, memory controllers, PCI buses, and so on. If the South bridge fails, the following conditions may occur:
< br >
1. Failure to boot the computer: A broken Southbridge may cause the computer to fail to boot because it controls the memory and PCI bus, and if these functions do not work properly, the computer will not boot.
< br >
2. USB interface is unavailable: Southbridge is also responsible for managing the USB interface, if the south bridge is broken, it may cause the USB interface to be unavailable.
< br >
3. Network connection failure: Southbridge is also responsible for managing the NIC interface, if the Southbridge is broken, the network may be unable to connect.
< br >
4. Memory is not recognized: The South bridge is also responsible for the memory controller, if the south bridge is broken, it may cause the computer to fail to recognize the memory, or the memory will not work properly.
< br >
5. Performance degradation: A broken Southbridge can cause a computer performance degradation because it controls important components such as memory and PCI bus, and if these components do not work properly, the computer's performance will be affected.
< br >
In short, the south bridge is a very important component of the computer, if it is broken, it may cause the computer to not work properly, need to be replaced in time.
Computer south bridge broken phenomenon is: motherboard temperature is too high for a short time, boot running after a period of time automatically shut down or crash, you can touch the north and south bridge chip at this time, if the temperature above is hot, it means bad. The Southbridge chip is responsible for the communication between the I\/O buses
