Well I dont know mate Untill I get the new machine flashed up I am battling on with something around 120 mhz and 128MB ram.a bit slow but does not crash if I am running poser only. does crash if i am on the net using Internet Explorer. I would still have a look at your Virtual Memory Just type it in Widows help is the easiest way and when you get there make sure it is in the Windows manage auto mode
