I noticed that my fans on my PowerMac G5 are running a little more than usual while my computer is pretty idle/has very few applications open. I then noticed that the graphs of my CPU usage in iStat go up and down like the spikes on the back of a stegosaurus. I have it pictured here, and sometimes it's more defined... I am wondering why the heck this "SystemUIServer" keeps going in and out of using like 7+% of my CPU and 2% of the CPU. Then there is this other thing I am seeing now called "WindowServer", and that has been spiking around as well. Normally my computer's CPUs barely have any activity at a moderate/idle stat, but that has changed. Anyone know why? I am not running 3rd party Dashboard widgets, and the only foreign thing on my toolbar is iStat menus, which I haven't had issues with before. Any ideas? Thanks! P.S. Come to think of it, "WindowServer" is beginning to be the largest culprit here, next to "SystemUIServer"!
