Here is my problem. I own a Toshiba Satellite pro L300-EZ1004x. The laptop is pre loaded with windows XP professional, and I decided to upgrade to Vista Business with SP1. When loading webpages or downloading, My audio/music will crack up until the web page has been loaded or the download is complete. I download DPC Latency checker and noticed that when loading web pages while music is playing, I get multiple bursts of RED spikes up in the 8000us-16000us range. I tried disabling and enabling all devices but the problem still exists. I never had this problem with XP only with Vista. It is incredibly annoying and any help or suggestions would be awesome!Also i forgot to mention that this problem only occurs when my laptop has been on for a couple hours. When I reboot, the problem goes away until I leave my computer for a while and come back later.
