Hi,

Have you tried reinstalling Windows 7? Please do try this link from Dell that will show you how to do a complete factory reset that may solve the issue.

If this will not work, you'll need to order a factory reset disc from Dell to reinstall Windows 7.

Here's the link where you can order them from.
