Everytime I try to open my computer, my documents, even control panel, my computer pops up this message- "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.", and doesn't open. How do I fix this? this is a vista home basic on my dell inspiron 1501. Note: My computer was reformatted with recovery disk, dunno if that has something to do with this. Additional details: same message pops up when trying to open up control panel and windows update; on administrator still has same problem; can access files though by, for example, opening itunes browsing through hard drive for song and play it, or same with a word doc. but still has problem.
