Please help, keyboard and mouse not working

Once I get to my desktop I cannot use my keyboard, touchpad, or a mouse. So my computer is totally useless. I want to try a system restore but can't. I've tried starting in safe mode and it does the same thing. I pushed F12 to enter boot mode and I tested my mouse, keyboard, and system. They all checked out ok. The keyboard and mouse even operated in this mode but once I exited to the desktop they quit. (My CD also said it tested fine but I know this isn't true since it hasn't for sometime and I think I just need to repair the driver for it.)

Please any help or guidance would be greatly appreciated!

Hi cbspon,

See if any of these things will help you further:

Go into the BIOS by hitting the Del key during bootup. Click down to PnP/PCI and hit enter. Then check if the "Resources controlled by" is set to Auto. If not, set it to Auto. Then "Esc" back to the previous menu and select "User Password". See if it is set or disabled or requires an entry.

Are you using a ps/2 mouse/keyboard or usb? Does the alternative work?

If the above doesn't help, you may wish to replace or refresh the CMOS battery. This step can involve losing all your settings, so you may wish to read more about this step before taking it. For laptops this is not as straightforward as for towers and desktops. Please see these two articles: http://murfsgarage.cybertechhelp.com/cmos.htm
