OK... It could be a few things, but the most common thing is...

Your friend either has the 32 bit edition of Windows which can only see ~3GBs of memory, or he has the 64bit edition, but 1GB is reserved for graphics.

If you have the 64bit edition, you should not have a problem seeing the full 4GBs unless again, you have memory reserved for your graphics card.
