I am guessing it may be some bad memory. I know that CentSO can support much
more than 4 Gig of memory. Get something like the system rescue cd and do a
memory test to see if it makes it through.
Also, remove the old 2 gig of memory and see if it works in that
configuration. If it does, then you may even try to mix and match the chips.
It is possible they sent you the wrong memory.
