Could also be that he's using analog vga with no choke and is picking up RF or other line noise somewhere. Still think its RAM though. Asus wouldn't see that on an rma unless it was an issue with integrated video RAM and not shared RAM which comes from the modules he takes out before he sends it back. Oh and AFAIK, manufacturers don't generally test equipment before they process the rma. Just the $.02 from someone who doesn't know what they're talking about and likes dell (actually Apple). :)
