    KarenB,

    * Off topic but I would suggest you may need to seek some Security advice asap.
    Refer your post 5
    .............Right now my security is whatever windows provides and an outdated version of McAfee that came preinstalled with my computer.
    *Just in case....

    > Have you a Windows 7 disk?

    > Have you a System Backup made PRIOR to the date when things started to lag?

    KarenB, once you have fixed the problem with Windows not recognizing that it is genuine, you can look into using Microsoft's antivirus software if you are unwilling to purchase one. Microsoft provides their antivirus software for free to genuine Windows users. Microsoft Security Essentials - Free Antivirus for Windows

    Last evening I left my computer on stand-by because I had to go out, didn't want it to close down and cause lag on start-up, and I wasn't finished removing updates. I came back later in the evening and continued but the computer lag was as bad when I signed in as if I'd started it up all over again.

    Then while I was removing the updates, the computer froze completely. It's done this a few times before as well while I've been having this problem. I tried to open the task manager and a warning popped up that my computer was having trouble and I should wait or shut it off manually on the on-off button - again, not a first time occurance, so I shut it off.

    Then I tried to open it. Black screen. Every time. I can get into the BIOS, but that's it. The OS appears completely dead.

    Are you able to start the computer in Safe Mode?

    If so, the chances are the problem is driver related and quite possibly the video driver.

    Please check this Microsoft article for further help: Why is my screen black when I start Windows 7?

    Nope. It never gets as far as the windows start-up logo. I get as far as the Acer logo and then black.

    OK, on the basis that a problematic update is a red herring, would you consider a Startup Repair?

    Failing that, you might want to try a Repair Install.
