keyboard problems- HELP!!!!

[Spawndude]

When I turn on the computer it goes through the memory check, finds the HD and CD, then it gives me the following message

"keyboard error or no keyboard present"

This has happened on "3" motherboards !!!!!!

One is a Tyan 1590s with an AMD K6-2-350, 64 meg, an old Permedia 3000 PCI video card, Seagate Bigfoot 6 gig HD, 250 watt Gateway power supply.

Two have been an FIC 503+ with an AMD K6-2-475, same memory, video, and HD as above, a different 250 watt generic power supply.

I've tried 4 different keyboards, one brand new, the keyboards work on other systems.

When installing I've taken all the precautions regarding static discharge and have powered down and been properly grounded when assembling and diassembling.

Have I somehow managed to fry 3 motherboards?????

If so any idea where the problem might lie???

The power supplies maybe???
The video card ??
The CPU's?

I've totally ran out of ideas as to a solution

From keyboard error to motherboard error, my diagnosis:
Check pins of plug for damage, whether plugs are plugged in all the way, whether any keys are accidentally depressed on power on (one of them might be stuck; press every one to make sure they aren't), whether the BIOS is up to date, whether the BIOS settings for the keyboard are correct, whether the PS/2 ports are grounded to the case correctly, whether the PS/2 ports are not damaged, and whether the PS/2 ports are well soldered to the motherboard.

Any one of these can cause that error.

To fix the BIOS settings, you would have to "clear/reset" the BIOS settings by shorting a jumper or dipswitch on the wmotherboard. This procedure will reset all the settings in the BIOS and will require you to re-enter them. I'll spare you and assume that you know how to do this already. If not, refer to your motherboard manuals.

Hope that helps.
