I was on my computer messing around on Facebook, and my computer screen went white, and turned to black. I have not received a blue screen saying the computer was being dumped. My computer is a Dell Inspirion E1505 and run Windows XP Media Center addition. When trying to restart the computer all I get is the motor trying to run, and a blank screen and nothing else happens. I don't know where my cd is to re-install. Can anyone help me, or is my computer finally out of commission?
