Question about Abit KN9-SLI Motherboard

1 Answer

Power Up I recently installed an ABIT KN9 SLI mobo and applied power. The fans and indicators came on for about five seconds and the green 5VSB LED was extinguished at that time. I did try another power supply to no avail. All suggestions from anyone are more than welcome. Bob

Re: Power Up

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.

The fans and indicators working for a sec would normally mean that your power supply is Ok. This flash of current must trigger a switch in the mobo to start the boot process. This is not happening. The RAM is a principal player here if it does not connect the memory to the processor nothing will happen. Assuming the RAM is correct and has worked faultlessly before, remove and clean the teeth with an eraser. This prob can also be caused by the VGA card not connecting. Usually alarms sound if your mobo speaker is connected but that depends on each mobo. These are basic steps that usually start machines that have been inactive for a time or have recently been exposed to high humidity. There could be other faults...............

Try checking the jumpers on the motherboard. A lot of the SLI compatible boards have jumpers that need to be configured properly. You can find out the positions by checking the motherboard manual. Are you using an SLI capable video card or is the video onboard? I just ask because I had the same problem once while trying to install an SLI video card. I had no picture on the monitor and I couldn't figure it out for the longest. Finally I found the answer in the motherboard manual and it turned out to be a jumper that was set wrong. Hope this helps.

Have an Abit IC7 motherboard in a system given to me by a friend. I have two problems in getting the board to boot. 1) One of the brackets that the spring mount uses on the Northbridge chipset fell off...

1) The bracket is a simple push fit one - it just pops in and locks in there when pushed.
2) Simple test (assuming that the processor , video card and the memory have been tested in another motherboard and are good): remove all the disks and try to start it up into the BIOS - if you can't then the problem is in the motherboard. As a last hope reset the BIOS and remove the battery for one hour. If it doesn't starts even after that then the board is dead.
The DVD burner will power up and seek even if it's not connected to anything else - all that it says is that the unit is working normally.

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.

Abit kn9 sli overheating ??

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.

I just received a hand me down system with the abit kn9-sli motherboard. After installing a new amd 64x am2 6000+ processor and a new hard drive...when I powered on the system...the systemboard speaker...

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 :)
