The PC in question is about three years old. It's an AMD 1.3 Duron
procesor. The option was never available as far as I was aware. We are
using it as the kids PC but it would be good to us less power.
If the option was never available, it could very well be that the
motherboard just doesn't support it. That's an older processor. If this
is an OEM machine (Compaq, Dell, etc.) then you would look for updates
for the BIOS and other hardware on the OEM's website for your specific
machine. If it is a custom or home-built, you would need to look for
those updates on the motherboard mftr.'s website. To determine the make
of the motherboard and other hardware, you can either open up the
machine and look or install a system inventory program like Everest
Home Edition from Lavalys (free):

You need to be very careful updating the BIOS and if you aren't sure
about doing any of this, think twice about it. You might want to ask a
knowledgeable friend or computer professional instead of doing this
yourself.
