It sound like a problem with the connections between the memory and the
motherboard. When I was building my computer I pulled memory in and out and
finally I was about to give up it started working. I however noticed that
it was only recognizing 64 MB and I had 512 MB. I went into my bios and
noticed there was a turbo mode. When I enabled the turbo mode all memory was
suddenly recognized.
I noticed that when I was installing the memory I could move the stick
around slightly so it wasn't fitting snuggly. As long as I got it working I
left it alone.
