I did some reading before posting :http://www.techspot.com/vb/all/windows/t-30298-Computer-lag-every-2-seconds.html I just did a fresh install of Windows MCE over a 80Gig hard drive (with 120 slave w/ previous files before the reinstall + format) I thought all my problems were fixed (from my other previous posts) but a new problem has arisen. My computer has lag. every2-5 seconds or so, it lags, cursor jumps, when playing music using WMP, music becomes disoriented, choppy, and just plain ugly. I made sure I was using the correct sound drivers (downloaded from dell; specs below) so i dont think it's a driver problem. Defragging BOTH IDE drives didn't solve the problem. Upon reading the post (above) i did look over some of my services and disabled some that aren't necessary. I did monitor Performance using Windows Task Manager while running some music w/WMP. While it's idiling, it can be anywhere from 8%-15% (with bitlord and trillian running) but with completely nothing just the browser open its 0% (seems normal) when music runs, it can be from 8% and spikes to high 90s to 100% CPU usage. that is when the lag occurs. I've included HJT log and a screenshot.

Thanks.
