Welcome to the forum,
I had the exact same problem about 2 weeks ago, updated my RAM from 1Gb to 2, installed a Nvidia GeForce 6200 Video card as I had only on board video and that was not enough for my system. All works fine now, and loads well with no stuttering at all.
Hope this information is of some help to you. Please post back if you need further assistance.
kind regards,
