Hello, Your CPU is probably fine for video editing, but I really must tell you that 2 GB of RAM is marginal at best, and it is even worse if anything is running on your system while you are trying to edit.  email, browser, windows widgets, anti-virus, firewall, etc all consume RAM while they are running.  My system is a Quad Core and I run 6 GB of RAM, and that sometimes does not seem like enough.  As an example, right now, if I look at my system resources based on the processes, services and applications that are currently running, 50% of my RAM is already in use, that is 3 GB of RAM being used, and all I have open right now are MEP, email, my browser a few windows widgets, and the processes that windows actually needs to run.  Movie Edit Pro is currently consuming just under 1/2 GB of RAM, so everything else is consuming 2.5 GB  that is half a gigabyte more than your system has.  You start adding files to your video project, transitions, titles, effects, etc.  and suddenly the application runs out of available system memory and it has no option other than to crash.

Do yourself a huge favor, add at least 2 GB of RAM if you really want to edit video.  You may also want to check out this link   http://www.zdnet.com/blog/hardware/how-much-ram-do-i-need/17491
