I have an Inspiron 1420 which I had reverted from vVista back to good old XP Pro.
I have literally been searching for an answer to this problem for the past (at least) 2 weeks. I can't play any audio or video on my laptop without getting a static type sound and both are also very glitchy and choppy.
I have tried reinstalling the drivers and all of that. I changed back to sp2 and tried a few things regarding that as well. I am definitely at my wits end and I am really hoping someone can help me.
