I've got a 2gh Dell Latitude D610 with 1.5gb of RAM. When I play MP3's, my computer intermittently (and repeatedly) runs the hard drive solid to the point that the whole computer locks up, the song stutters and the computer freezes for various amounts of seconds. Sometimes it runs fine but then random seconds later the hard drive will start to run again constantly for 30 seconds...I have no idea what it's doing. This also happens when I'm not doing anything else except for playing MP3's. I've tried several different audio applications and it all produces the same result. It's actually quite embarrassing when I put on a set and go to sit down with some friends and the music is stuttering all over the place. I can play KOTOR with a move running in the background and my browser open with 15 tabs open, but can't play an MP3 without the computer "locking" up. Any help greatly appreciated.
