Yup, its your RAM. Maya requires a minimum of 512 to work properly. With 256MB, you're barely getting it open. I bet it takes like 2 mintues to open, right? Upgrade to at least 1 GB and you'll have no trouble with the rest of those specs. I run a Radeon 64MB DDR card, which is classed as the 7200 series, so your vid card should be fine.
BTW, Dragonhawk, when you're quoting someone else, try using the QUOTE feature when you post. I thought I had deja vu when I was reading that. heh heh.
