Vista - Folder Image Problems

Had Windows Vista Home Premium running for about three weeks.

The major problem i am having with it, is the images in the folders keep
changing, all the time on a regular basis.

For instance in My Music folder the image of the albums keep changing over
to the wrong albums. And i am now getting album covers showing up in my
program files and in My Tv directorys.

I change them back but next time i go back in they have changed.

I would be most grateful for any advice.

Thanks Ian
