I have a computer that i use daily as i am in school and there is no question i must have it. When i woke up this morning to use my computer i noticed the mouse would not work. So i restarted my computer, still nothing. I am using a USB mouse and have tried it in every port and nothing. I tried it in my other computer and the mouse works there so ???i know it is not the mouse. Also when i do plug it in it does light up so power is being recevied but still nothing. I am freaking out as this computer is the one with everything on it. I have no idea how i can resolve this... any help at all would be awesome...thank you.
