Question : Problem: How to fix paging file and CPU usage in my machine?

Most of the time my mahine (Laptop) CPU usage shows more than 90% without running any applications. And if i run small application like excel 2007 then it shows 100%. And also most of the time my machine paging file shows more than 2 GB. My machine has only 2 GB . B/c of this issue my machine is running very slow. I am deleting files fom temp folder and every week i am doing defragmentation. Still it is slow.
Most of the time i am running SQL Server 2005 SSIS package and Scripts and using office 2007. My machine OS windows XP professional and 32 bit.
Please advise me. Thanks in advane.

You obviously have something or many things running on your machine.  Identify what they are in task manager (or Process Explorer http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) and stop them, if they are unneeded.  You may need to remove them from startup as well http://windows.about.com/od/troubleshooting/ss/start_programs.htm.  I have found that antivirus programs are usually set up to run on startup by default, which you could change.
