I went to <http://www.microsoft.com/windows/products/windowsvista/editions/systemrequirements.mspx> to see if I have the right stuff for Vista. I found the "System Information" program in "Accessories," and had no trouble finding my disk space. I know I have DVD, audio, and internet. The problem is I don't know whether my processor is 32 or 64 bit; my system memory; whether or not I have Direct X; or how much graphics memory I have. I don't understand most of what "System Information" is telling me. Is there anywhere else I can look that explains this stuff in layman's terms? I'm currently running XP on an HP Pavilion zd7000 laptop with an Intel Pentium 4. Thank you. P.S. - I'd just like to say that as far as internet forums go--and not just those about computers--MSFN has been the most helpful to me. I've only asked a few questions, but I always get clear, concise, and friendly answers. So thanks everyone!
