And that is not all. When I turned on my computer yesterday, my usernames were not on the Welcome screen. So, I was able to find out that I should run a CHKDSK /p. So I did that, and it found one or more errors, but it didn't tell me what those errors are, and I tried to do a CHKDSK /f and that is not a valid variable. So, I was able to talk to my brother who works with Windows every day. He told me I could log in as Administrator, as long as the password was set up. So that is how I'm able to be on here now. When I go to the control panel, and click on User Accounts, the window is completely empty. But when I go and right click on My Computer and click on Manage, I am there, along with the other only user, my hubby, and we are not x'd out. In that same window, it shows the Device manager, and that is completely empty. In the Add/Remove programs, all of my programs are listed there, including the sound card that I installed about 3 weeks ago, but is not showing up here. I have run Antivirus software, and nothing is coming up. It did a really thorough scan when I booted up one of the times today, and still nothing was found. I tried running in Safe mode, and after I logged in as Admin, the screen was completely black, and stayed that way. I do not want to have to re-install windows, if I don't have to, and I would like that to be the very very last resort. I'm not sure if I will be able to back up what I need even if I do re-install. I was on the computer on Monday and it was fine. The only thing I did on Monday, was try to delete a CMedia PCI driver out of my add remove, and it didn't work. I did find it in the registry, and I just changed to give me full permission so that I could get rid of it in the add/remove. I am the administrator, and the Master Account holder. I hope that someone can give me some idea of what is wrong. I just got it back, too, and now this!
