I've produced the link for the download, but firstly remove the audio driver and reboot before trying to reinstall the drivers. Make sure you have very little applications running in the background before trying this.

SOURCE: please can you tell me the components of the following chipsets. north bridge,south bridge and I/Out put chipset

For the Dell Optiplex GX150 Desktop PC?

Motherboard chipset: Intel 815E

Northbridge chip: Intel 82815
Southbridge chip: Intel 82801BA

Under the subheading - Chipset - scroll down with your eyes to -

Look to the right.
You will see - 82815 - under - Part Numbers.
That is the Northbridge.

To the right of that, you will see - ICH2 - under Southbridge.

Scroll the page down, until you come to the BOLD heading -
Southbridge 8XX chipsets.

You will see ICH2 is Intel part number - 82801BA

The I/O controller hub is in the Southbridge chip.
I do not know what the Super I/O chipset is.

[ The Northbridge chip should be under a finned Heatsink. If so, you will not be able to see the Intel part number.

Looking at the motherboard as a map, with the Processor to the Top, and Ram Memory slots to the Right, the Processor is NORTH.

(Ram Memory slots are to the EAST)

Coming down the motherboard, the Northbridge chip is under the Processor.

Come down further, and slightly to the right, and you will see the Southbridge chip.
It has Intel 82801BA on it, with other Intel information ]

HOWEVER, here is a list of Super I/O chipsets,

[ It comes up to the Wayback Machine. Wait a couple of seconds, and the Super I/O chipset page will come up ]

If this is a general question about the Northbridge chip, Southbridge chip, and Super I/O chipset;

Motherboard diagram,

CPU stands for Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.

The Processor communicates with the Northbridge chip, through the Front Side Bus. (FSB)

The Northbridge chip communicates with the Southbridge chip, through the Internal Bus.

The Southbridge chip communicates with the Super I/O chipset through the LPC Bus. (Low Pin Count Bus)

The Northbridge chip handles the faster capabilities of a computer.
It handles the Processor, Ram Memory, and HIGH-speed graphics.

AGP (Accelerated Graphics Port), and PCI-Express, are HIGH-speed graphics.

A graphics card inserted into a PCI slot, or Integrated Graphics, is
NOT high-speed graphics. This is handled by the Southbridge chip.

The Southbridge chip handles the slower capabilities of a computer.

and Audio. (Sound)

This is more information on the Northbridge chip,

For more information on the Southbridge chip, simply left-click on the blue - southbridge, in the end of the first sentence.
(....the other being the southbridge)

You can also search the following in Wikipedia, by typing them in the search box to the upper right, and clicking on the magnifying glass icon.

Northbridge (computing)
Southbridge (computing)
Front-side bus
Internal bus
LPC bus
Super I/O chip, and so on.

1. function of bios chip 2. function of north and south bridge chipset 3. cpu function

Hi there. Here is a brief description of those components found on the motherboard.

1. BIOS chip: This is known as Basic Input Output System and the chip contains the base instructions on how to boot the PC. All personalized settings can be configured in the BIOS such as CPU overclocking.

2. North Bridge: This component works with high speed hardware components such as RAM and PCI-E cards.

3.South Bridge: This component works with slower speed hardware components such as the hard drive and USB.

4. CPU: Central Processing Unit, this is basically the brain of a computer and this component is the one that does all calculating of data. So when you run an application, the CPU processes the data involving the application.

Please rate and comment, thank you.

Please help me identify where is the north and south of motherboard

Its normally printed on the board, north bridge and south bridge. But I would suggest that it would be advisable to go to the ASUS website, follow links for downloads and support. There, you should be able to download a user manual for your motherboard and all the drivers, which you will need to install when you get your PC up and running.

You must of handled to motherboard incorrectly and possibly fried the SATA/PATA controller, usually found on the North or south bridge. My friend had the same problem, leaving the motherboard useless. IF this is a laptop your screwed (I.E. motherboard is junk). If this is a desktop you can either replace the motherboard OR you can buy a SATA/PATA card that inserts into the PCI/PCI-E slot to create a place to plug your hard drive in. Hope that helps.
