I know this question may sound stupid, but I don't know how to find "My Computer" in Vista. I need to get there to format my sansa e260. I clicked start but "My Computer" isn't there

Try press windows and e.

It is now renamed Computer. if that isn't there, right click on the start button and Click properties. it should open into the Star Menu tab. click customize. Make sure that under computer, the box saying display as link is selected.
