I'm really having to squint and struggle just to ask this. Today I woke up my computer and when it "woke up" the screen suddenly went from the normal brightness to as if someone took the brightness and turned it ALLLL the way down to where I hve to shine lights and squint to see whats on the screen. I'm really blindly typing right now and hoping I get this right. Now my computer is normally on 24/7 so I'm wondering if it's just over ehated? A thing also comes up right when I turn it on saying their are errors. Now if I put it in sleep then wake it up the screen will be bright for a few seconds and then go back to no brightness. I've called tech support but they have no trouble shooting center. I have to pay $40 to send it over to geek squad I don't have $40 so I'm out there. Could my computer just be overheated or could it be something else??? I'm trying to figure this out fast because I have homework to do and my college is online with no other computer to use (my library card is no good cause I owe them money) What could be going on? My computer also has to thing on it to change the brightness.
