Hello Everyone I recently upgraded my Hard drive from 80 GB to 400 GB. Before the upgrade I didn't have any problems when I played a video file or MPG or AVI files. But after the upgrade, I started having some problems of computer freezing everytime I play a VIDEO FILE. Here are the symptoms Before freezing, the sound trembles (like stuck) and sometimes the sound manages to overcome but most of the time the computer finally freezes. I am not sure whats the problem. Is it the Hard drive upgrade? I have no other problems besides that. If anyone can suggest me some solution, I'll really appreciate. I tried using averest home edition to check my system. My sound card driver is Audio Adapter Creative SB Live! Value (CT4780) Sound Card I tried updating my drivers for the sound card but was not able to find for model CT4780, and I am kind of confused whats the right steps to update. If you have any questions, feel free to email me. Thanks a lot --nanda saini

I think you upgrade your Ram from 256MB to at least 512MB or higher.
