CPU usage 100% after fresh Install

I use an old HP 510 business laptop for rough adventure travel, with a weak Celeron and 1gb of RAM which never hangs or bogs. But I also have a perfect 7 clean install with a clean boot and only do light multi-tasking while browsing the web. It's nearly 10 years old now but hangs in there even tho I expected it to be stolen or drown in a wave years ago. No one will steal it now.

To get a clean boot is very helpful no matter how much RAM, since freeloaders on your CPU/RAM and startup can also spy on you. In msconfig>Startup uncheck all except AV and gadgets if you use them, then in msconfig>Services choose "Hide all MS Services" and uncheck all but AV & gadgets there, too. After reboots check back to make sure nothing writes itself back in - if so turn it off in its Program Prefs or Uninstall it.

With less than 2gb RAM you also want a lightweight AV like MSE or Avast6 and want to limit your gadgets. Allow your GPU to decide if it wants Aero, nothing more.
 
If the CPU usage is permanent than there might be some process running in the background but also after fresh install and drivers or even updating windows if you notice the CPU usage is moving up and down for sometime even when your on desktop and not moving a mouse...
