What's a good easy to use live CD benchmark testing tool? I have a lot of aging HP computers where the caps on the MB are swelling and leaking and one of the symptoms is that it's really slow. Obviously I can pop the cover and look at the caps, but not every computer with bad caps are slowing down and there can be other reasons for the performance issue. I don't want to install any software into Windows XP and would rather leave the installed OS out of the mix.

I was hoping for something that someone could boot from a USB stick and use with ease.
