Just reviving a thread because I can't find the answer anywhere else...
I just want to know if this is normal. The CPU usage jumps up and down constantly when playing a song (see below). The flat bit in the middle of the graph is when I paused the song, and then I de-paused it and the peaks came on again. Each peak is no more than 10%, but it's still a bit odd.
Winamp was pretty much the only thing running.
WinXP, 2.04GHz, 384MB RAM, 5 GB of HD space left
Any reply much appreciated.
