Test your memory.  I had bad RAM in a system a couple of years ago.  It
manifested as weird problems and hangs and then difficulty booting, etc.
 The biggest headache of the adventure was the slow corruption of the
hard drive file system resulting in the loss of some data.

Because Linux actually makes full use of your systems resources, it uses
all you RAM and expects RAM to perform correctly.  Windows is far more
"quietly tolerant" of RAM errors even though the RAM will continue to
corrupt things under that OS too.  At least that has been my experience.

Boot a Linux install CD and choose the memory test option.  Let it run
at least a full pass.  Any error at all can be a problem for the OS and
you should remove the offending module to run with less RAM or replace it.
