How can I find out why I have high CPU usage?
Are there any apps besides the Windows Task Manager to tell why my XP machine is showing only 10 for CPU usage by applications when looking at task manager processes, but displays 50% usage at the bottom of the screen? The 50% seems more correct since everything is running slower than normal. This has been happening for months. XP is fully patched and updated with current service packs, has 4gb ram (only using 3.5) and plenty of HD space.
Thanks.

This is a great program here that actually lets you look and each and every single processes individual CPU usage in great detail. I use it to see if I'm being bottlenecked in a game by my CPU. This should be just what you're looking for.

Looks like a virus to me. Go to Filehippo.com and get "Malawarebytes" for free and run it-it's great for finding virus's. Avast is free and also at Filehippo.com, it's the best anti-virus I have found and I tried a lot of them.

Your maybbe running programs your processor has to work hard to run.
Or your pc may be dusty, just opening up the tower and cleaning the dust out with compressed air can improve speed.

task manager should tell you what processes are slowing you down. it could be you have multiple security programs on your computer, itune, firefox uses alot to. you might want to defrag your HDD.
