If you do not have the Abit KN9-SLI motherboard manual, I would like you to download it, (Free), and follow along with me,

Abit Support > KN9-SLI motherboard > User Manual download page,


On this page go down to the heading > Mirror site, and click on the country nearest yours.

A small window will come up > Opening kn9_series.zip

If the empty circle to the left of Save File does not have a Green dot in it, Left-click on the empty circle.
Now go below, and left-click on > OK

This is a Zip file. A Zip file is used to send a large file more easily over the internet.
(It is a compressed file)

Watch the heading in the small download window that appears. This tells you where the file will download to.

It can download to your desktop screen, or the My Documents folder, or a sub-folder within the My Documents folder called > Downloads.

Close all windows see if the file went to your desktop screen. The file name is > kn9_series.zip
Then left-click on Start, and then on My Documents.
Then double-click on Downloads.

When you see the file name double-click on it.

Go to the left-side of the screen, and left-click on > Extract All Files.
Now click on Next, Next, and Finish.

You will be looking at a small window with a red PDF icon in it, and the file name underneath.
Double-click on this PDF icon.

There are three ways to go to the page I need you to go to.

1) Look at the Bookmarks menu to the left.
Scroll it down until you see the heading > Connecting chassis components, and under this heading > FAN Power Connectors
Left-click right on FAN Power Connectors

2) You can use the blue down arrow at the top of the PDF file, and go to Page 18.

3) The page number box is to the Right of the blue down arrow.
Put your mouse cursor in the page number box.
Left-click once
Type 18
Press the Enter key

Look at the small rectangle with > CPUFAN1
Observe where it shows the pins that are Ground, 12V, RPM, and Control

Ground is Negative. Usually a Black or Green wire

12V is 12 Volt. Usually a Red wire

[It's a DC motor that is used for the Fan. DC uses a Positive (12 Volts in this case) connection, and a Negative connection. (Ground ]

RPM is Revolutions Per Minute. Colors vary from manufacturer to manufacturer. (More on this in a second) This is the wire that the computer (BIOS) uses to read how fast the fan is turning. How fast in revolutions per minute.

This is the wire that the computer (BIOS actually) uses to speed the fan up, or slow it down.
Colors vary according to manufacturer.

Your CPU fan connector only has a 12 volt wire, Ground wire, and an RPM wire.
Therefore you eliminate guessing which one is the Control wire, because the CPU Fan doesn't have one.

You should have a Red wire (12 Volt), Black or Green wire, (Ground), and another wire of some color. This wire is the RPM wire.

In the illustration for the CPUFAN1 connector on the motherboard, you will see a small rectangle on the left of the connector. Then four dots that represent the pins of the connector.

The small rectangle to the left represents a Tab. Also referred to as a Key.
This tab only allows you to connect the connector in one direction.

IF, when the CPU Fan connector fits on the motherboard's CPU fan connector, AND the wires do NOT line up correctly with the pins they're supposed to go to, you can change it.

You use a needle to take the wires out, and then put them back into the correct socket holes of the CPU Fan's connector.

At the end of every wire going down into the CPU fan connector, is a female metal terminal.

Looks like this,


Use the Zoom In icon at the top ( + ) to enlarge.

The left side of the Molex (Female Crimp) terminal connector is where the wire comes into.

The two tangs that stick up all the way to the Left, are crimped around the insulation of the wire.
Coming to the right a little bit, are areas of the connector that are crimped on the bare end of the wire.

Going all the way to the Right side, you will see tangs that stick out the sides. Two of them.
You can see the one in front clearly, but just the tip of the one on the other side.

Crude illustration > This = the side of the connector > l.
This equals the side of the connector with the tang sticking out > l/

Where the wire comes into the connector is the BACK of the connector.
The end of the connector that plugs in is the FRONT of the connector.

The needle goes up into the socket hole of the wire, from the Front.
It then depresses the tang down.

(Slides up the side of the female terminal, and the inside of the socket hole)

Now go to the other side, and depress that tang down.
Now you can slip the wire out of the Back of the connector.
(You may have to use a bright light, and possibly a magnifying glass to see the tangs. After you know where they are, set the magnifying glass down, and depress them)

When you get the wire out, gently use the needle underneath the tang, to ease it back up if it is flat against the female metal terminal.
Use care because if you bend the tang too far up, it will snap off.

All wires removed, put them back into the socket holes of the connector where you need them.

Have questions, or need clarification to what I have stated, post back in a Comment.

(On the CPUFAN1 connector on the motherboard the tab, or key is to the Left;
A) The top pin is for the Ground wire. (Black or Green wire)
B) The next pin down is for the 12 Volt wire (Red)
C) The next pin down is the RPM wire

(The last pin is for the Control wire which your CPU Fan doesn't have)

Sorry I was so long and 'Windy'.

Are you sure the 4 pin connector is going in correctly? Some motherboards have an 8 pin socket, and the connector can be placed in improperly. The symptoms you describe indicate a dead short on the power line when plugged in.

Try downloading drivers for your motherboard, there may be an audio patch or some other driver you are missing

The problem could be a failed electronic component, and no cooling remedy will solve the problem. When some components fail, they result in high heat conditions.

Abit KN9-SLI... | Answered on Aug 06, 2009

Usually the sound is called bios beeps. They let you know in advance if there is a problem.

Usually a high low bios signal ( like an old german siren) means a cpu issue.

Check the processor and cooling fans, and check it's temp....take two aspirins and call me in the morning...LOL :)


Abit KN9-SLI... | Answered on Aug 03, 2009

This is probably an over heating CPU(processor). Make sure the fan over the processor is working. If it is, check to see if the heat sink is fastened properly to the motherboard - if you can push on any of the corners and it moves in than there's an issue.

Also look for a thick layer of dust that might be blocking the air flow.

I am encountered that kind of problem before i am also trying to replaced some of my comuter parts but the problem still there. I am only solved the problem when i installed pctools spyware doctor. pctools removed a lot of spyware virus in my system and i installed the registry mechanic to fixed the registry. After i reboot my computer the problem is gone. the spyware virus sometimes is cause of the compuer to shutting down automatically without any warning messages.

The problem is ***********, there is electrolytic capacitor leaky sometimes color blue or green. Try to check if here is capacitor that on his upper top is slight blown or deform. f you can see you need to replace this if you know how to use he soldering iron or else you need to buy a new motherboard

So after 5 seconds it won't come on again at all, or it runs for 5 seconds each time? What else do you have running on this computer? I'd suggest disconnecting all non-essential devices (hard drives, all but one memory chip, any expansion cards other than video) - if one of them has a short, they can pull down the power supply (regardless of the condition) and cause it to shut off exactly as you've explained. Let me know if that makes a difference (it obviously won't boot without a hard drive, but it will get far enough to see if that's the problem). If that doesn't make a difference, let me know and we'll try something else.

Depends on your local authority but if uninhabitable by way of no kitchen,toilet, water etc there is usually no charges.
In my area if we stick a skip outside that is deemed to be acceptable for no charges.

If they use the wide ribbon cable, you need the cables with two connectors. Then set on drive to master and one to slave, or set both to CS - for cable select. When you restart the computer, the OS will do the rest.

Hi Klex,

I was able to find the website address www.kdsusa.com through one of their products on Newegg, but the site appears to no longer exist. They also had a phone number listed (1-800-283-131) but that too doesn't seem to work. I have the feeling that they have either close their business or ended their operations in the U.S..

Sorry I didn't have better information for you.
