BleepingComputer.com: Mouse/keyboard Won't Work. Bootup Problem?

Hi guys,

I have a bit of a problem. Yesterday after manually updating Vista from microsoft website it asked me to restart. I've always allowed it to automatically update once every 24hours but this time I happened to be at microsofts website and decided to do it manually. I did and this is where my problem began...


It restarted and booted to windows with no visual problem. However, I noticed my mouse and keyboard did not work. I tried other usb ports (including the front) to no avail. I removed my printer,microphone and card reader usbs and tried the keyboard/mouse again, it did not work. I did try the keyboard/mouse in another computer and they worked perfectly. So i ruled out a periphereal failure.

I later booted from the Vista Reinstall disc and my keyboard and mouse worked fine. So from here, I realized it's likely a file or two corrupt or not working correctly during bootup. When prompted whether I would like to go to a safemode or normal boot up my keyboard worked fine as it accepted the <enter> and scrolling keys. However, once in windows safemode my keyboard/mouse or any usb device would not work.

Is there some deleting or switching around of bootup files I can work with from the command prompt:?

Appreciate any help

If the input devices don't work from within Windows - IMO there's an issue either with your USB drivers and their support of the OS, or it's a corruption of Windows.

To start, I'd try a PS2 mouse and keyboard to see if they work OK. If they do, then Windows is likely to be alright.
Then I'd look into your BIOS to ensure that legacy USB support is enabled, and to ensure that you've specified that you have a PnP OS installed.
Should that not work, then I'd suggest trying a repair installation of Vista: http://www.bleepingcomputer.com/tutorials/repair-windows-with-windows-startup-repair/
