Vista is the work of the devil. I trashed my hard drive on this laptop (on purpose) to get rid of Vista and then loaded XP instead. Took a while to get all the drivers in preparation for the downgrade, but by golly was it worth it. Compaq says this laptop cannot be run using XP, I say Compaq must be off with the fairies as it is most certainly running perfectly well using XP.
Simple rule in this house. Daddies laptop, children have own PC, wife allowed to use desktop machine. One breaks, other options available.
