Er, just a new keyboard may have worked, as in your bios it probably has hault on keybaord error

I booted up my Dell computer last night and, at first, my mouse was frozen. I restarted it and a screen came up saying "keyboard failure". I'm not sure what to do. I did try unplugging them, plugging them back and rebooting a few times, with no success. Any ideas??

if you can get to the BIOS settings check them to see if the kbd (I'm guessing it's USB) is actually enabled.

If it is a USB keyboard and it is not enabled in the BIOS and was working previously you may want to consider replacing the CMOS battery.
