Missing key bindings

[Chris <cmayes@mailandnews.com>]

Hi.

I've posted this before, but maybe some of you missed it...  Anyway, my
problem is that I am missing some very useful key bindings all of a sudden.
Some of these include contol-alt-delete, control-k, control-f, control-w, and
a number of others.  Other bindings such as control-x and control-s still
work.  

The same thing happens in my RedHat partition,so I sense an ominous Hardware
Problem...  They tend to be more worrisome than software problems :-P  One
odd thing I have noticed about the box is that it emits a rapid clicking
throughout the BIOS bootstrapping (much like the sound that it normally only
makes during its RAM count).  This sound goes away once it hits my boot
manager.  I have an Epox MVP3G-M MoBo.  Does anyone have any idea what or
where I should check for problems?  I'd like to fix this ASAP since Emacs
and Jed are rather irritating to use in my system's current state :-P

Thanks,

-Chris
