The Fedora Core installation CDs also are equipped with the memtest86
tool.  Insert the CD and reboot.  At the boot prompt, enter 'memtest' to
start the test.  It is usually best to let it run a few passes.  If it
finds errors, you'll know it.  ;-)

As for hard drive testing, boot the Fedora CD into rescue mode and use
the following:

badblocks -ns /dev/hda

You can replace /dev/hda with any other hard drive you might have.  This
will perform a non-destructive read-write test.  This will also show
status information on a single line.  If it encounters errors, it will
print the error location on a new line.  If it only outputs a couple of
lines and finishes, your drive is fine.  If you end up with a screen
full of numbers, you've got a problem.
