[QUOTE="pigoo3, post: 1528289, member: 56379"] The % Idle and % User values will fluctuate. I would say once the computer has fully booted & no apps open...the values should not fluctuate more than a few percent. But...in case you didn't know...some applications can "auto-launch" when starting up the computer (rebooting). Many times this includes the two anti-virus programs you have installed (Sophos and MacScan)...so when your % Idle dropped to 71%...this could be because one or both of these apps were doing something. Ok...so one last thing to check: - With the computer freshing rebooted (and no apps lauched by the user). - Open Activity Monitor - Click on the "CPU" tab at the bottom. - At the top of the Activity Monitor window (and slighly to the right)...there's a drop down menu...make sure "All Process's" is selected. - Look thru the list (scroll down as necessary)...and see if there's anything that's taking up a lot of CPU resources. With the computer freshly rebooted & no apps. lauched by the user...there shouldn't be any LARGE "drains" on the cpu resources. For what it's worth...when I reboot my computers (and no apps launched)...my % Idle is usually 95-98%. I have no anti-virus programs running. - Nick [/QUOTE]
