As soon as it started it had another error. I was confused at this pointa nd then all of the sudden my computer shut down. I had no idea what happened. So I go to boot my computer back up and it starts up, lights go and everything, water cooler turns on, and then nothing shows in the screen. It blank it doesnt get anything. I have no idea what is going on, Please Help!
