You're confusing processor resources with RAM resources. Norton is warning you about the latter.
How much RAM do you have installed? Click the Start Orb, right-click Computer
and select properties
. The amount of RAM you have will be shown in that box under the System
Also, click the start orb, type in Resource Monitor
. When it shows up in the search results, click it.
Click the Memory
tab and sort the list by Working Set
. That will show, in order, what programs are using up your memory.
Chances are that you have programs auto-starting in the background and using up RAM. Use a program such as Autoruns
to list those programs. Guide to using Autoruns
Bleeping Computer has a large resource of startup programs here
to help you decide what to disable.
