CPU % extremely high RRS feed

  • Question

  • I have Win 7 home premium with 4.0 gig mem.   When booting, I have anywhere from 65 to 80 processes  and  in task manager I show roughly between 3 ad 25% cpu usage. My carrier supplies me with avg download speed of 200+ mbps.  Yet when I use IE11 my cpu usage goes up drastically.

    Just opening one page takes up2-300 k of cpu and my performance monitor is maxed out around 100%. So, if IE is so slow, I can’t take advantage of my internet speed since it takes forever to load anything. I also have all add-ons disabled.  Anything else I can change?

  • Hi,

    Please try,

    Tools>Internet Options>Advanced tab, check "Use Software rendering instead of GPU".

    You should also

    1. Update your PC with Windows Updates (from IE select the Tools>Windows Updates menu).

    2. Check your Adobe Flash version... Start>Control Panel>Flash 32.... Updates tab, click the "Update" button..

In your case I would wager that you are visiting a site that uses a number of Flash videos, which will affect CPU usage, depending if Software v GPU (Graphics Processing Unit) is used on your machine.
