It takes a very long time for my computer to boot up. My cpu usage runs anywhere from 4%to13%. I have cleaned up, defragged,virus scanned, gotten rid of all spyware turned off programs running in the background,(ones that I thought were safe to turn off)and re-booted. Now what?

I am going to recommend a test site

PC Pitstop: Free PC Diagnostics, computer help and Tuneups (http://pcpitstop.com/)

It will point out some of the problems in your computer

And suggest what should be done to fix it

Thanks for the info Biggsie. Looks like a great site. I ran a full test and it said "This system performs well on our benchmarks, and should have plenty of power for most applications." So why the slow boot?

What brand of computer is it?
