There are a couple of tools on the internet to check your computer for Hyper-V compatibility. If you have had your computer for a number of years then the answer is most likely no.

Check AMD machine: http://www.amd.com/us-en/Processors/TechnicalResources/0,,30_182_871_9033,00.html
(if this fails, then download from here: http://www.box.net/shared/kmzjkh6pou )

Check Intel: http://www.intel.com/support/processors/tools/piu/

Enjoy!
