35 entries on my PC wouldn't be a problem. Your CPU seems okay. Just that the RAM that is in your PC is a "potential" for the slowdown.
The recommended minimum amount of RAM installed in the Windows Operating System is 512MB. Half of that might be problem... if you're running a lot of processes (just my guess).
Do you mind if you explain a little more on the "hog"? Like how is your computer slowing down?
Have you cleared the cache, and cookies from your browsers? How about the temp. files on the computer? Will a disk defragment do?
