I left for work this morning and my mouse was working fine, I shut off the comp before leaving. When I got home I booted up the computer and the mouse is not being recognized at the windows log on screen. I've swapped another mouse in and the same non responsive mouse occurs. When I go into bios the keyboard is recognized and I can navigate in there. However at the windows log on screen I can't use my keyboard to log on to windows.
So my question is two fold.
1. How do I log on to windows 7 using only a keyboard?
2. What would cause a working mouse to stop being recognized when the computer was off all day? Any help will be appreciated.
Edit: Nevermind about log on using only keyboard. Keyboard is not being recognized by windows 7 either at log on screen. However it is recognized in bios and selecting between safe mode / normal start up.
