Keyboard Controller died

Thats the PS2 connection but not what you would call the controller.
In my experience if you loose your keyboard there isn't much you can do to repair it.
My only suggestion is you enable USB keyboard support in the bios and try a USB keyboard instead.

stduc,

I would not think that using "canned air" or cooling a chip would render it non-functional.
It appears that you have identified the connection port for a keyboard/mouse. Couldn't see the rear view to see if there are two ports or not.

The controller is an I/C chip. You know similar to your BIOS/CMOS chip. Unfortunately, on most modern boards these are soldered to the mobo vs in a socket.

It appears that you have identified the beep code correctly. You can view beepcodes for AMI here:
AMI Beep Codes

Upon powering up, there is no video.

This would make one think that there might be more than a keyboard controller error going on.

You should try resetting the BIOS. See the mobo manual for the precise procedure as different board mfg's define varying procedures for this. If you/he does not, can not locate it, they are usually available at the mfg's site in PDF form.

Try this and please post back with results

"I know everything..I just can't remember it all

The part with the X on, is the port for the keyboard & mouse. I can't see anything on the mobo that looks a likely candidate for the keyboard controller chip. So I'm kind of assuming it's inside the connector?

I already removed all cards, re-seated the video card and RAM. There is only one stick. I've also cleared the CMOS. I even tried removing and re-fitting the CPU (I used a new heat pad). So at the moment it has no disks either.

I'm inclined to agree it's a dead mobo.

[blue]paparazi[/blue] Without a screen or a keyboard, how would you suggest I enable USB keyboard support in the BIOS?

It is very likely that the keyboard controller is part of a larger chip on the M/B. And, as Martin says, when they go, the M/B goes.
I've iced SSI (small scale intergration) elevator control boards without problems, but you are probably dealing with LSI and larger chips and smaller traces so the shrinkage may have broken things loose.
Cooling under power is a diagnostic technique. It tends to cause questionable parts to fail. So your friend may have done a good thing and identified a part that was about to die.

Give the wrong symptoms, get the wrong solutions.

So can you enable usb keyboard support in the bios in this case, with no video and no keyboard? Paparazi must know a way to do this?


Good advice + great people = tek-tips

You have possibly pushed a conductive dust under a chip, or between chip pins. Conductive dust can be metal burrs that come off every time that a screww is crewed or off.

I suggest that you try recleaning it again. It can't hurt.
