    The CheckSUR is not clear - having fixed the problems, and the SFC also succeeded in fixing all the problems it found.

    With any luck, Windows Updates will now work - do a manual Check for Updates first, and then install only the oldest update found, to check the system.

    Noel, my computer has begun to freeze again. Actually, sometimes I can tell that behind the frozen "Starting Windows" screen, it is starting. I can hear the bell indicating when I need to enter the password. But since I'm stuck with the same screen, I can't try downloading updates. So then I tried doing it in Safe Mode, but apparently updates are disabled in Safe Mode. So it seems I need to fix what you think is a memory problem that is causing the screen to freeze. Can memtest+ work on Safe Mode? If so, please help me get detailed instructions on how use it. Appreciate the help.

    Memtest creates its own boot disk, and runs completely outside Windows, so isn't affected by any Windows problems.

    Unless you would like to give me detailed instructions on how to use it, can you refer me to a good site that can? The sites I have gone to were confusing.

    www.memtest.org - you want the Auto-installer for USB. Memtest86+ - Advanced Memory Diagnostic Tool
    Download the zip file and extract it, then run the extracted file, and follow the instructions. You will need a USB stick (empty it first, as it may delete everything on it!)
