I would say three - the third being your signature with all the HTML 
crap and logos.  Please don't post that garbage to this list?  Not all 
of us are on broadband and all the cruft takes forever to load.

That is *highly* unlikely.

I would recommend you boot off the install or rescue CD with the command 
line:

memtest86

You more than likely have a hardware issue, specifically memory.

Yes, instead of using iptables-save, do "service iptables save" as root, 
this will save your running rules in /etc/sysconfig/iptables.
