LPCXpresso should install and run on your machine. We run on Netbooks with similar specs and they run OK. However, the Pentium 4 will be very slow.
One issue could be the amount of *free* RAM. The IDE can be a bit of a hog for RAM, and so the more, the better. If you are running lot of other apps, that will reduce the amount of RAM available, and it will then start paging (quite heavily).
When you start LPCXpresso, does the IDE stop/crash/hang? If it starts paging, it could be that you didn't leave it long enough to finish starting up. If it crashed, there is a log file that you could post, and we can see if that give any clues. The log file can be found in <workspace>/.metadata/.log
