im using a wireless keyboard/mouse. two nights ago i was cleaning out the inside of my system with the electronic cleaner in a can or whatever either way after that i tried plugging in the little usb for my mouse and its not reading it now. i can plug it into my laptop though and it works fine. Ive tried every usb port on my desktop and none of them pick it up. it turns on fine from what i know of. i cant see anything load because it doesnt show anything on my screen till i move the mouse around even on startup. can someone help me? thanks
