Hi KelliSue,
Thank you for taking the time to post the steps what fixed your issue!
In a default install of Windows, f6 during boot shouldn't do anything. It sounds like (and I have no way to be sure) that the company that built the computer may have added some sort of Diagnostic Program that is access thru f6 during boot and whatever
the program did corrected the problem. Whatever happened, I'm just glad your issue is resolved.
Thank you,
Darin MS
