I have this problem where when I'm downloading stuff (through bittorrent or whatever), I get these CPU spikes which causes stuttering. The System Process shoots up to 70-80% and then I get a stutter and the computer freezes a little. I notice this most when I'm playing a video or mp3 since the stutter is very obvious. But I don't think it's a sound card/video card problem because these spikes come up even when no sound is being played and no video usage other than desktop display/web display is being done. This may happen when I'm not downloading anything but it's very rare in this case (though when it does happen when I'm not overtly downloading it's probably because something IS downloading in the background). Any one have any ideas? *Windows XP *Athlon 2400 *512 MB DDR RAM *Albatron KX400-8XV Mobo *Western Digital HD (boot up drive) *Hitachi HD *Sound Blaster Live! (I think) *Video card shouldn't matter since this was happening with my old my video card, I got a new one, happened with that, that one broke, put in a different old one and it still does it. *Generic Ethernetcard *USB Card in there but it's pretty much unused. Thanks.
