cpu usage erratic but can't see why

[Guest]

when i click on the processes tab in task manager the system idle process is usually 99 or 100 and all the other process are 0. however the cpu usage shown at the bottom of the task manager window is erratic. For example t jumps from 21% to 36% to 90% to 2%.... I can't see any process running that account for this. i'm baffled, please please explain

It could be, perhaps, Windows doing housekeeping, or your media player
searching for titles to add to its library, or one of your programs looking
for an update...there could be hundreds of perfectly legitimate reasons for
CPU usage. If you're doing all the right things to protect your computer
from the Internet and you're not experiencing a particular problem, don't
worry about it.

I'm having the same situation, and good luck finding a
solution posted somewhere. Everyone says "don't worry
about it", however, I don't know if your computer is like
mine (I use mine at work), but, when the CPU is using 80
to 90 percent of it's capabilities, my system is running
so slow it is unbearable.

I was having the same problem once and a while with XP
pro. Finally figured out that it was either a USB 2.0
card reader that created the high CPU usage or a file
stuck in the print spool. I think that either can create
this situation. For the USB issue just unplugging it
made my CPU usage go from 40-80% to 1-2% while not seeing
any change in the processes or tasks.

Update virus definitions and run full anti-virus scan.

If you do not have an anti-virus programme installed go here for a free anti-virus scan:

Also download Adaware ( Freeware version ) and / or update Reference file from http://www.lavasoftusa.com/support/download/
