Same "keyboard failure" problem here

Answers :

When the system is booting up does the keyboard lite up momentarily? When booted does the CAPS Lock button light when pressed? If not then the problem is the motherboard. They are not difficult to replace and fairly cheap if you get one that will accept the same processor and RAM. Unfortunately this problem is not a repairable one.
The Solution to this occurance of "Keyboard error" , which is apparently being caused by a cracked trace or feed through on the motherboard related to the Keyboard processor, was to change both mouse and keyboard to a USB device.. USB devices are coupled thru the south bridge and therefore take a different signal path for the interrupt and data paths than the PS/2 devices. Once the interface devices were switched to the USB type. And the ports disabled in "Setup", the POST error indicators have been green. And the BSOD "fatal error" screen has not reoccured..
\015\012 The cause of the crack in the traces or feedthroughs of the motherboard is most likely related to the lack of cooling this unit experienced when the rug fuzz and cat hair was allowed to gather on the cooling vents and CPU cooler fins.
\015\012Most owners do not read the users manual more than once, and a curssorary scan at that time, so they forget the needed cleaning to protect the thermal health of their compters.. Clean them at least each 6 months and oftener if they are sitting on a long fiber rug or the household has multilple pets in it...
