I tried running in on Dell 3000 with pretty much the same result, It was xp, onboard graphics and 2gigs of memory. DSL connection. From what i remember my discos were a resource problem.The game was just a bit much for my computer, although somewhat playable with everything turned down to lowest setting
I now have a Dell 8400 w pcie and 4 gigs and have solid FR and still have a good deal of the "eye candy" on. Not one disco from a resource problem yet in 2 months, actually only 1 disco the whole time, but that was because of my ISP going down
