I can't help you in CPU testing

I just thought that considering what you said, you may be too quick to point
to the CPU

I'll try first the usual suspects: memory, temperature, HDD (Maybe you check
it already).

CPU at 100% is quite normal.

Do you have lm-sensors (with sensors-applet for gnome or similar) installed?
It gives you a easy look at CPU activity and CPU and HDD temperatures. In
some chipsets, that is.
