Hello, Hope to get some advice; I upgraded from 512mb to 2GB RAM on my Dell Laptop. I'm getting wonderful results on my browsing speeds but when I watch videos on youtube, there seems to be a freeze up every 2-3 seconds where the video stops and audio is lost. This doesn't happen on my other netbooks and laptops. Do I need to adjust some other settings as well? I switched to Mozilla thinking the new browser would help; same result.
