You can add a heat sink to the Southbridge chip as listed at this link:
http://www.frozencpu.com/cat/l2/g33/c173/list/p1/Ultra_Quiet-Chipset_Coolers.html
Microcool Chipsink Southbridge Passive Heatsink
The word passive means no need for screws or clamps. A special teflon tape sticks to the chipset. If you feel this may not be enough you can always add a side case fan that will direct air flow right on the Southbridge chip & also feed fresh air to the whole board. http://www.xoxide.com/80mmfans.html There are tons of cooling here & more passive coolers as well for both Northbridge & Southbridge.
I'm sure this will make a difference.

What means sb pwr


'SB' stands for StandBy. When the motherboard is connected to the power supply but not turned on the SB voltages are supplied to different parts of the motherboard. In some motherboards you are able to charge devices like Phone without powering on the computer, that's because of the SB.

The SB in turn triggers other voltages used for the motherboard.

My southbridge chipest gets very hot


this is normally a sign of either a power supply failure or a faulty component, it's more likely the southbridge failing, I had this issue with my ex-server, so I got a laptop heat pipe and some thermal compound, strapped the part to the southbridge and modified the fan so it ran constantly, and this sorted the problem long enough that I only had to retire the server in late 2012 after 9 years of rather intensive service, but the easiest way to resolve this is to get another board, I reccommend Asrock, Asus, the later MSI boards, and some mainstream boards, the best boad I've had was a Crosshair Formula 5, but they're expensive, for value, Asus and Gigabyte.

I had pc intel motherboard 82801 but audio card can not detected


Intel 82801 refers to the Southbridge chip, of the motherboard chipset;
for an Intel 800 series motherboard chipset, for the Intel Pentium 4 series processors,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsets

Notice in the chart under the heading - South bridge;
ICH2, and ICH4 and ICH5 and ICH5R

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Southbridge_8xx_chipsets

Does NOT state anything exact about the motherboard.
For this you need the Model Number.

Granted the Southbridge chip, of the motherboard chipset; is what handles the Slower capabilities of a computer.

Audio is one,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

[Note CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
Does NOT mean personal Computer.

This technology applies to YOUR motherboard, and not to motherboards that support the Intel Core i3, Core i5, Core i7, and Core i9, processors ]

However the Southbridge chip handles Audio through the Audio chipset.

Driver: Small piece of software that allows the Operating System to communicate with a device

The device is the Audio chipset.
You didn't state what Windows O/S you are using.

The reason BIOS doesn't detect the Audio chipset, is because the Driver is gone. Audio driver.

(Windblows lost the address to the driver)

IF, I have the model number of the motherboard;
Or,
IF I have the manufacturer name of the computer, and it's model number;
I can look to see if Audio drivers are available, and instruct you how to download, AND install.
I also need the Operating System used.

Windows what?

CPU (Processor) Support,

http://eu.msi.com/product/mb/945GCM5-F-V2.html#?div=CPUSupport

With your motherboard, the motherboard chipset consists of a Northbridge chip, and a Southbridge chip; for the motherboard chipset,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

The Northbridge, and Southbridge chip are so aptly named; because of the relation to how they sit on the motherboard.

Really.

If you looked at the motherboard as a Map; the Processor (CPU), sits due North. The Northbridge chip is located close to it.
The Southbridge chip sits South, or towards the bottom of the motherboard.

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

AGP and PCI Express are HIGH-speed graphics technology.

A PCI graphics card inserted into a PCI slot, or using Integrated Graphics; is NOT high-speed graphics.

The Southbridge chip handles the Slower capabilities of a computer.

1) Anything inserted into a PCI slot, or connected to the PCI bus.
2) IDE bus
3) SATA bus
4) USB bus
5) Ethernet bus
6) Audio (Sound)

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

[Just for edification while I'm here;
The I.C., or chipset used for graphics; is the graphics chipset, or more properly known as the G.P.U.
Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU ]

The Intel Core i technology, did away with the Northbridge chip.
It also uses QPI, or Quick Path Interconnect; instead of a Front Side Bus, (FSB),

http://en.wikipedia.org/wiki/Intel_QuickPath_Interconnect

http://en.wikipedia.org/wiki/Nehalem_%28microarchitecture%29

http://www.hardwaresecrets.com/article/535

Plus you have an LGA 775 processor socket, and the Intel Core i processors use either an LGA 1156, or LGA 1366, or LGA 1567, processor socket,

What is a Southbridge chip, and what does it do?

Primer:

The motherboard chipset is the Northbridge and Southbridge chips.

(For your motherboard's technology. Motherboards that support the Intel Core i3. i5. i7, and i9 processors, do not use a Northbridge chip)

The designations Northbridge and Southbridge, were applied to the two chips, due to their placing on the motherboard.

If you look at the motherboard as a map, the Processor is due North.
The Northbridge chip is always mounted close to the processor's socket.
Usually has a finned Heatsink sitting on it.

The Southbridge chip sits more South, or towards the bottom of the motherboard.

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

Using a graphics card in a PCI slot, or using Integrated Graphics that is connected to the PCI Bus, is NOT high-speed graphics.

High-speed graphics is either AGP (Accelerated Graphics Port), or PCI-Express.

The Southbridge chip handles the slower capabilities of a computer.
Handles a graphics card inserted into a PCI slot, or Integrated Graphics connected to the PCI bus.

Also handles the;
A) IDE bus
B) SATA bus
C) USB bus
D) Ethernet
E) Audio (Sound)

Motherboard diagram,

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

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

This is why people cannot call a personal computer a CPU.
If you were looking at this diagram, you would be ALL mixed up.

"Computer connected to a Northbridge? But the Northbridge chip is on the motherboard, AND the motherboard is inside the computer? What are they talking about Martha?"

CPU = P-R-O-C-E-S-S-O-R }

The Asus Rampage III Extreme motherboard, DOES NOT use a wimpy Intel ICH2 southbridge chip, so I know this isn't the motherboard you are referring to.
(Uses an Intel ICH10R. Part number Intel 82801JR)

So there you have it. Your Southbridge chip is overheating.
What to do about it?

Put a Heatsink on it for passive cooling. Better yet put a small fan on the Heatsink, and make the cooling better. (Dynamic cooling)

Here are two examples of a chipset cooler,

I have pendium d system . i want to sound driver


Doesn't matter if you have an Intel Pentium D processor.

What does matter is what Southbridge chip is on the motherboard. It handles the audio (Integrated Audio) of the motherboard.

If this motherboard is an Intel D945GCCR model, here is the driver download page from Intel Support,

Intel has an automatic update and detect drivers feature.
I would suggest using it.

(The digital signature has been verified, so click on RUN.

I would have clicked on RUN anyway. It is INTEL, sheesh!)

Would also like you to read Troubleshooting audio issues,

[ Southbridge Chip:

The Southbridge chip is part of the motherboard chipset.
The Northbridge chip, and the Southbridge chip.

{Does not apply to motherboards supporting Intel Core i3, i5, i7, and i9 processors. Different technology is used }

The Northbridge chip was so aptly named because if a motherboard were a map, the Northbridge chip would be setting to the 'North'.
{It's located immediately south of the Processor, under an aluminum heatsink}

The Northbridge handles the faster capabilities of the computer.
The Processor, Ram Memory, and High-speed graphics.

High-speed graphics being AGP, or PCI-Express.
A graphics card inserted into a white PCI slot, or Integrated Graphics on the motherboard, is Not high-speed graphics.

The Southbridge chip handles the slower capabilities of the computer.
Audio falls into this category.

Motherboard Diagram. (The technology shown fits the Intel D945GCCR motherboard)

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

More information on the Northbridge chip. (And Southbridge. Click on the blue southbridge in the first sentence )

http://en.wikipedia.org/wiki/Northbridge_%28computing%29

The Intel D945GGCR motherboard uses a;

A) Intel 945GC Express chipset GMCH for the Northbridge chip.

(Intel 82945GC. There is an aluminum finned heatsink sitting on top of this chipset.
Looks like a meat tenderizer.
If it wasn't you would see Intel i945GC - 82945GC )

B) Intel 82801GB for the Southbridge chip.

(ICH7 - 82801GB. This part number you can see. No heatsink)

C) RealTek ALC883 audio

http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PFid=28&Level=5&Conn=4&ProdID=44

More information on the Intel 945GC chipset,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Core_2_chipsets

Under the Chipset heading look down to 945GC, then read across.
Now you know what;

Processors are supported
Ram Memory is supported
Graphics are supported

Can you elaborate the functions of this product....


NOTE*
The following applies to motherboards such as an AsRock K7S41GX.
It does NOT apply to motherboards supporting the Intel Core i3, i5, i7, and i9 processors.

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

A) CPU = Central Processing Unit. Another term is Microprocessor, or Processor for short.
The 'Brain' of the computer.

B) Front Side Bus. Also abbreviated as FSB.
The FSB is the 'Information Highway' between the Processor, and the Northbridge chip.

[Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit ]

C) The motherboard chipset is the Northbridge chip, and the Southbridge chip.

The Northbridge chip handles the faster capabilities of the computer.
It is named NORTHbridge, because on the orientation of the motherboard, it is to the North of the motherboard.

The Southbridge chip handles the slower capabilities of the computer.


D) The Northbridge handles the Processor, Ram Memory, and HIGH-speed graphics.
AGP and PCI Express are high speed graphic technologies.

A graphics card used in a PCI expansion slot, and Integrated Graphics are NOT high speed graphics.


E) The Southbridge handles Integrated Graphics, (OnBoard graphics. Same/same), and the PCI bus.
A graphics card inserted into a PCI expansion slot is one example of Southbridge support.

Any add-in card inserted into a PCI expansion slot, is in the PCI bus.
Therefore handled by the Southbridge chip.

The Southbridge chip also handles IDE (PATA), and SATA harddrives.
Handles USB ports, Ethernet port/s, audio, and the CMOS memory.

F) The Internal Bus is the 'Information Highway' between the Northbridge chip, and the Southbridge chip.

G) The LPC Bus is the 'Information Highway' between the Southbridge chip, and the Super I/O chipset.
The LPC Bus is also the 'Information Highway' between the Southbridge chip, and the BIOS chipset.

H) The Super I/O chipset handles,
Serial port
Parallel port
Floppy Disk Drive
Keyboard
Mouse


2) http://www.asrock.com/mb/overview.asp?Model=K7S41GX

What is the square metal grid-looking part in the middle of the motherboard and what does it do?


It is a heat sink for the chipset which is part of the architecture of the CPU Board. You may have two chipsets called the Northbridge and the Southbridge or one chipset.
The Southbridge is the I/O Controller Hub (ICH) which handles the PCI/ISA/PCI-X Bus, DMA, AC'97 or Intel High Definition Audio, Real-Time Clock, Mass Storage Hardware (Hard Drives, DVD Drives), Key Board, Mouse, and BIOS (Basic Input Output System).
The Northbridge MCH (Memory Controller Hub) or IMC (Integrated Memory Controller) handles memory and communicates with the CPU, RAM, BIOS ROM, PCI Express Accelerated Graphics Port and Southbridge Chipset.

Promise SATA300 TX2 Plus PCI controller card compatibility


Southbridge shouldn't matter as that is the controller for audio.
As the supported intel chipset is listed there should be no conflicts.
