    I'm running bootcamp windows 7 ultimate on a mid 2010 imac and every so often (usually from waking the cpmputer up but sometimes just randomly) the volume and brightness functions wont work.

    Sometimes the volume/brightness notification pops up in the middle of the screen and shows it going up and down but with no change and other times that doesn't even show up

    This used to happen on my windows 7 home premium too before I upgraded.

    I have the newest version of bootcamp's drivers as I only reformatted a few days ago.

    Any help with this would be brilliant.
