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!
