I logged into Windows and found that all of my user settings had been changed back to default. All the files that were in My Documents had been moved to Documents and Settings in C. I moved them back to My Documents and changed my settings back to the way I had them before. While surfing the internet a few minutes later, the system became unresponsive. I restarted the computer and logged in, but now I find that My Documents has completely disappeared. I can't even find my files in Documents and Settings. I had about 35 GB of music, so I hope I didn't just lose it all. Please help!
