Which particular 1GHz processor ? Or which laptop model ?
I still have time to post it back
If I were you, I'd do that and try out something else as it sounds like your little machine is a bit underpowered.
Also see here for Windows 7 system requirements

As you can see, Microsoft say 1GHz is the minimum requirement...... attempting to run anything in IT (Microsoft badged or otherwise) at a vendors published minimum requirement levels is a pointless activity (unless you are a book worm, tea drinker, or something else that will keep you occupied whilst you wait for stuff to boot/load ..... wait for stuff to process etc. etc.)
