I've read a post from december 2011 from James2k. Here his problem.
"
My XPS 15z has developed a very strange problem.
Every 5 seconds or so the mouse, keyboard, video and sound seem to lock up/stick.
What I mean by that is if I'm using the mouse, it will get stuck for a brief second, if I'm using the keyboard it will lag for a second.
Playing a video e.g. YouTube video shows this problem up as the every few seconds the video image will freeze up and the audio will play a horrible continuous tone for a second or so (Like it was stuck). I know sometimes lag can happen, but believe me this isn't normal and with the specifications of this machine, this isn't right.
My XPS 15z has been fine up until a couple of days ago, it had never shown this behaviour before.
I'm really not sure where to start with troubleshooting as I don't really have much to go on. What I did try is booting Windows into safe mode with networking. I only tested it briefly but from what I did, there was no locking up issue.
I'm thinking this is probably a driver/hardware issue, but if anyone could advise me on fruther troubleshooting tips, I'd really appreciate it.
What I've tried so far:
- Ran Dell Diagnostics (F12) Found no errors (Ran the thorough test mode)
- Ran chkdsk on hard drive, made a couple of modifications but no errors
- Memory is fine, no errors.
- Ran Dell Support Center PC Checkup. All passed
- Hard Drive passes SMART test and any other test
- Drivers are all up to date
Thanks,
James

Since my new XPS15 have this similar problem, i've tried to stop programs and services one by one to detect where the problem came from. Once I've close BitTorrent, to problem stopped. But it was not the program in itself. My issue came back when I was downloading from the internet to my computer. So, i have discover that each time i download something, the problem is here. Now, it is the fact of downloading, or the probem come when i write on my disc.
Is there a way to solve that without restoring my PC?
Thanks
