My pc had a virus so i installed a new version of vista ultimate (not an upgrade). Since then i have no sound and a message stating that there is ‘No audio device installed’.

I have presently have vista basic. Was wonder what upgrades are available and what benefit the upgrade gives compared to the basic vista. Also what is the cost factor re upgrading?

Or disable the entire internet security?
i’m using norton 360.3 for my protection.

I recently got my mums work laptop, and because it was a work laptop, it is restricted by all the settings and software and what not that the previous administrator used at my mums work. So if I upgraded from XP Professional to Vista Home Premium, would that delete everything? Allowing me to go on MSN and change the user-name and all that? Also, there is Windows Vista Home Premium Service Pack 1, and then there is the upgrade which is cheaper in most places. Can you only get the upgrade if you have the original? Thank you.
