According to the ifconfig source, it's frame alignment error.  I think
frame alignment error usually means that it gets a packet/frame that is
not properly aligned, IE not a multiple of 8 bits.  That definitely
shouldn't be happening that often.

That could be.  Though my intuition would be that a faulty PCI bus would
produce more in the "errors" field, because of corrupted packets.  If
other computers on the network work fine without the new desktop, then
its probably not the network.  If multiple ethernet cards do the same
thing, then its probably not the ethernet card.  That pretty much leaves
the OS (what v. of the kernel?  It's probably not the driver, if the
exact same thing has been happening with 3 different cards) or the
hardware (you aren't overclocking, are you? does the card share an
interrupt?)...

Well, that probably wasn't much help.  You should probably talk to
someone who knows more about ethernet (linux-networking mailing list may
be a good place to ask if noone here can help) :)
