You cannot change the processor.
I have no idea what those programs are. The names suggest games of some sort.
Click on the Start button, select Run... Type in "msconfig" without the quotes and click Open or OK or whatever it has there.
The System Configuration utility will open. Click on the Startup tab, then click Disable all and click OK. Reboot. On reboot, Windows will ask you if you want to keep the list of disabled programs permanently or temporarily (I think). If it does, select the temporary option.
See how performance feels to you. Some features may not be available (in particular, antivirus, etc., so be careful.) If you find performance is much better, then it may be that one or more of the startup programs is slowing you down. You'll then need to try selectively reenabling startup programs (same way as above, except click the checkboxes by each program to re-enable) to see which one makes the difference.
If you don't understand what this is doing or don't feel comfortable with it, then don't make these changes.
