The Northbridge is one of the most important parts of a motherboard's architecture.When it goes out there's not much you can do about it except get a new motherboard.
Maybe you mean "northbridge"? in that case:The northbridge has historically been one of the two chips in the core logic chipset on a PC motherboard. The northbridge is the memory hub controller.
The chipset of a motherboard consists of both Northbridge and Southbridge. Northbridge is the faster component, as it handles things such RAM and CPU. Southbridge on the other hand, takes things slow and handles components of the motherboard such as USB, Ports (audio, speaker, mic). The Northbridge and Southbridge must be made by the same manufacturer. For example, you cannot put a Northbridge AMD on a motherboard with Southbridge Intel.
Is a chip that implements the "slower" capabilities of the motherboard in a northbridge/southbridge chipset computer architecture.
A northbridge or memory controller is part of the motherboard that connects the processor to the main memory

The purpose of the 770 Northbridge chipset on the motherboard is to link the computer system's hardware to the processor. Like other computer Northbridge chipsets, they act like the nerves that send signals to the entire unit. The 770 is lower power due to smaller connectors, which makes it an effective chipset.
The Southbridge chipset manages onboard peripheral devices The Northbridge chipset manages communication between the CPU, memory, and the Southbridge chipset
To direct traffic to and from CPU, Memory, level 2 Cache, and the PCI and AGP ports.
