    Hello everyone!

    Yesterday I was working on my desktop, and Windows Update decided to pop up and install some automatic updates. I put it off by a few hours, so I could finish up my work and go to sleep. When I next tried to use the computer, I realized that somehow Windows Vista could not start. Once it got past the initial screen where I could access BIOS and everything, the computer would just automatically restart.

    So I pulled out my installation disk, popped it into the drive, and did a repair on my computer. It supposedly worked, and I tried to access Vista again.

    Now here's the problem that I'm currently having:
    The keyboard works fine while the computer is booting up. In other words, I can access BIOS and all that. However, once the computer reaches the Vista logon screen, the keyboard and mouse don't receive any power from the computer at all. I can't turn on NumLock or anything like that. Therefore, I can't access my computer at all to try and repair it.

    I tried a System Restore to right before it updated (or at least that's what I think the date stamp pointed to), but the problem persists.

    I use a USB Keyboard and Mouse, and my computer does not have PS/2 keyboard or mouse ports. I'm running Windows Vista 64 bit, and my computer (and hardware inside) is maybe a year old at most, so I doubt any hardware has failed.

    So basically I'm asking: Is there any way to fix my computer? Or will I have to get a Linux Live CD, back up my files, and do a clean install of Windows?

    If you need anymore information, please ask, and thank you for helping!

    Edit: Any New Information
    -Safe mode does not work, as the keyboard and mouse don't respond, so I can't get past the log in screen.
    -It is likely not a problem with my mouse and keyboard, as they work with a Linux Live CD and in BIOS.
    -Newest observation: While loading up the drivers for Windows Safe Mode, I noticed that crcdisk.sys takes longer to load up than any other driver. COuld this be contributing to the problem, or is this normal?

    Can you do anything in Safe Mode?

    Safe mode doesn't remedy the situation. The drivers are still shot and the keyboard and mouse don't respond.

    Has there been any chage in BIOS? Go to BIOS setup and look for USB settings. Check if legacy USB support is enabled. look around for any other USB settings.

    Also, try booting with just the kb, and then with just the mouse to see if either works alone. Unplug all other USB devices.

    There is NOTHING that Windows Updates or driver changes, of any sort can do to mess up your USB connected keyboard (and exclusive, meaning no PS2, ports on your computer... as more and more are becoming) can do to prevent the USB keyboard (and usually the mouse, as well) from working with your computer at the initial startup time.

    That means that you can get into the BIOS setup routines - - - unless the USB keyboard has a problem.

    So, using the proper keyboard presses you should be able to get into Windows Safe Mode. Once you get into Safe mode, then you just delete any and all keyboard and mouse drivers. No special drivers, for those two, are in place when in Safe mode, so you should have no problem in deleting them. Then you re-boot and come up into regular Windows.

    In regular mode, the default USB drivers are there that will give you good communication to any USB mouse and keyboard. The drivers, beyond what is built into default Windows, are only needed to access special and/or extra features of the mouse and keyboard. The normal typing mode (letters, numbers, most type-able characters) and the mouse movements and just the left and right mouse buttons will not need any additional keyboard or mouse drivers.

    Once you get that running, as expected, then you can evaluate whether you want the additional functions your keyboard or mouse might do for you.
    (For example, I have the very nice and expensive MS Entertainment 8000 Bluetooth keyboard and mouse. I have loaded the drivers to the keyboard to get some special function key selections beyond what are already recognized by the default Windows driver. I have not loaded the additional MS mouse Intellipoint driver to gain some goodie functions that the mouse can do with that driver. The mouse and 3 buttons and track-wheel still work, and a bit more for the extra two mouse buttons. I can define what I want those buttons do, but I don't need that extra function.)

    So, delete what you have added, get back to basics, and see what gets going again. Maybe you have a problem mouse or keyboard.

    Elvandil: Legacy USB is enabled, and booting with only the keyboard does nothing.

    ChuckE: My USB Keyboard and Mouse are functional. I can use them on any other computer, and they work in BIOS. In addition, they work when I boot up my computer using a Linux Live CD.

    The problem persists with Windows Safe Mode. Booting into it results in the same problem - my keyboard and mouse don't receive any power, so I can't get past the log in screen.

    While booting up Windows Safe Mode to try again though, I realized that Windows was hanging while loading up crcdisk.sys. It took a MUCH longer time to load that up than any other driver. Could that be contributing to the problem?

    I've also edited my post to add in the additional information that I've posted.

    It always takes some time for thast disk scan with crcdisk.sys.

    Just to try and eliminate one or the other, just have the keyboard plugged in. You really can do most things without the mouse. You don't need to click a button with a mouse when you know what keyboard pushes are needed to do the same thing. (Usually the arrow keys, or Tab key, and the Enter or Space key will get you to the desired button and effectively "click" the high-lighted button).

    See if that keyboard alone gets you past the login screen. If it does then perhaps the basic Windows mouse driver is bad. See what you can do to replace it.

    If the keyboard still does function, then try it the other way, with just the mouse and not the keyboard. Now without a keyboard you won't be able to type in any needed passwords, but perhaps you don't need a password if you never used one at the login screen (some people don't use them). If you can get past the Windows login then you can try the mouse to possibly select and do some limited Windows things. But even being able to click on some things, even just at the login screen, tells you that the mouse is getting power - that it is working. If so, then perhaps the basic keyboard driver is corrupt and needs to be replace. Although, without an ability to use the keyboard makes getting the fix a whole heck of a lot harder. Good luck with that.

    If all else fails, you may need to reload the entire Windows OS again. You might be able to do a repair of the OS, too. If you decide to wipe out the old OS, you can save your old data files if you remove the drive and install it on another computer to read and save off what you want.
