Funky hardware problem

[Alan Garrison]

So I sit down at my server last night, and I notice 
that the computer isn't responding very quickly when 
I type stuff.  I was just at a console, no X or anything.  
Every keystroke takes about half a second to get 
processed.  My first thought was that perhaps it was 
the new keyboard I got (that real nice Logitech 
ergo/cordless beauty) which is actually attached to 
my KVM.  I switched the keyboard with a corded one, 
and the problem still occurs (1. Not a keyboard 
problem).  I checked my processes and nothing was 
killing the CPU, and "top" said my load average was 
all zeros (2. Not a process problem).  I tried 
rebooting, and I went into the BIOS setup.  The 
thing was responding just as slowly in the BIOS 
setup as in the O/S (3. Not an O/S problem).  Now 
I'm getting worried that the motherboard may be 
the culprit.  Besides the slow respond time, 
the motherboard seems to think its OK.  It states 
the correct CPU clock speed and memory capacity.  
Since I'm at work, of course I forgot which 
motherboard I have in there, but it is a K6-2 
system, 300 MHz, 128M ram (in a 32/32/64 config).
The keyboard is connected via PS/2.  I think the 
motherboard is my Gigabyte 5AX (I'm at work, and 
I'll check when I get home).  Other things about 
the system work fine, the network response seems 
normal. 

Is anyone familiar with this kind of problem, and 
do you know if its the motherboard or not?  I'm 
going to be fscking pi55ed if I have to get another 
one.
