If you do a search in this forum, you'll find many threads about this topic and many advises that could make your system more stable. There are many people who have a rock solid system (like myself, for example) and others who have many crashes.

Some general advises from my own personal experience (but nevertheless you should do the search I suggested):

• If possible, get a computer dedicated for Vue (or for CG). I have two computers, one for Vue and one for everthing else. My Vue computer is disconnected from the internet and therefore it doesn't need antivirus, firewall, antispyware, etc. I only run graphic applications in this computer (Vue, Geocotrol, Poser, photoshop, etc). I have no widgets, the GUI is optimized for performance (disabled Aero and all that fancy stuff). I don't even have a screensaver.

• Update your drivers (especially graphic card, but also others).

• Make sure you have the latest build of your Vue version (get it in e-on site).

• If you have a 32 bit system, get a 64 bit. You won't regret it. Even if you have 4GB, if you have a 32 bit system Vue only uses 2GB maximum. If you have complex scenes, those 2GB are used very quickly. Check your resource usage in the Vue lower right corner (where it's displayed the polygons, you can see resources instead). If it goes below 10%, you're in a very bad situation. In my system (64 bits Vista), I never went below 70% free resources, even with really heavy scenes.

• Run Vue as administrator (right click, run as administrator).

Hope that helps and don't forget to see other threads. :-)
