Both me and my brother have recently landed ourselves new Dell XPS 420's, with 32bit Vista OS's.
My brother got his first, and then when I saw how much more powerful it was than my few years old heap, I begged for my own. He straight away had the issue of every 30-60 seconds, the computer would stutter for about two seconds, both in video and audio. I couldn't solve the issue myself, and he - rather oddly - refused to tell our dad about it, or go and google a solution for it. When I got mine a few weeks later, I don't think I noticed it at first or it wasn't happening. After a while though, it started up, and began to really eat away at my sanity. Whether I'm raiding on WoW, racing around on rFactor or just trying to listen to some music, I get this regular duh-duh-duh within the video and music.
I've looked around many popular technical help sites, and Dell's own support forums, used my own PC's troubleshooting programs and checked to see if it was itunes or my speakers, to which it is neither I believe.
Any help is really appreciated, I'd like to game and listen to music in peace
I am not sure this relates to you and your brother's issue or not. I had a similar issue with my Inspiron E1705 which runs an XP SP2 operating system. After much research I found the following post that helped me fix the audio stuttering problem. The issue with my laptop was the access method for external devices where the data transfer is not done by the central processor (like DVD & CD drives). My IDE ATA/ATAPI controllers were defalting to PIO mode instead of DMA. This forum explains it very well and shows how to fix it. I was nervous about doing this myself, but it worked.

I found the solution to this problem on this site. It should work with other systems with the C-state control option.
The solution that worked is below. Thanks to Tim Simpkins.

i also have a e1705. i had the same issue as you with the computer studdering and stuff. i narrowed the search down to the intel wireless pro wifi card. my solution well i removed the wifi card out of the computer and deinstalled the drivers as well. it solved my problem now my computer runs extremely stable and im using a linksys wifi usb adaptor. when i had the intel wifi card in my computer it. for some reason it would eat my page file in windows using 2gb of my page file and also everytime i rebooted my boot.ini file kept getting deleted for some reason. plus also when i played music files it would studder the mouse would freezee and my hard drive light would stay light up until i stoped the sound file. but needless to say once i removed the mini wifi card out and deinstalled the drivers and installed my usb wifi. my computer is 100% stable now and responds so much better. i donno if would help you out.
