On the Fedora 10 installation media, weither it is the Live CD, CD 1, or
DVD, the grub menu has a "Memory Test" option.  Select that to test the
RAM on your laptop.  If you tried to install with the Live CD, then when
you get the screen that it will boot in X seconds, press the down arrow
key to get to the GRUB menu items.
