My Dell Demension e510's (Window's XP) keyboard and mouse don't work

[rocksith]

Neither my keyboard or mouse are working on any of the 7 USB ports on my computer. My mouse was initially working, but I read somewhere if you delete the keyboard drivers you can reinstall them and it will work again. BUT when i was doing that I stupidly uninstalled my mouse driver so now NOTHING works. I can't try if it works in safe mode because my keyboard doesn't respond when i hit f12 during boot up.

When i plug in the mouse or keyboard, I get a window that pops up asking if I want to install the hardware, but it's impossible for me to do anything because my mouse and keyboard don't work! If anyone has any ideas I would greatly appreciate the help. Thanks!

It sounds like you tripped the usb circuit breaker, esp if the mouse laser doesnt light up when its plugged in. It should even if not driver is installed.

To reset it, with the power off remove the power cord and then hold in the front power button for about 20 seconds.
Leave the power cord unplugged several hours, or overnight if you can.
Then you can reconnect your devices and boot up.
