If you're using XP, NT4, or Windows 2000 Pro/Server/etc, you should have SMP support already from the operating system, and Poser's data threads are load-balanced betwixt the CPU's by the OS (SMP = more than one CPU, ie "Symmetric Multi-Processing".) 98 and ME won't cut the SMP mustard, though :/ The beeping comes from Poser's rendering subroutines being treated by the OS as distinct programs that end abruptly, hence the beeps (or something similar.) I get 'em here when I really load the machine down (Like when I run Poser, Carrara/RDS/AC3D or some other 3D model building proggy, Irfanview to see what previous renders look like, browse the web, get my mail, etc... having all of these programs open at one time, natch.) Won't hurt a thing - I wouldn't worry too much about it. I have almost the same box you do here, except I've only got 60GB of storage and half the RAM... then again I don't do animation all that much :) /P
