I am a pastor and one of the youth that are in our ministry gave their labtop to me to try and fix. I've tried t fix it but.... It is an Acer 5720z. It turns on but goes to a blank screen with a cursor on the top left of the screen. F2 will bring me to another screen with some start-up options and info about the cpu. I tried booting it with the other two options but it does the same thing (black blank screen with cursor on left) or comes with a message that says media error (with black blank screen and message on upper left hand corner) and doesn't move. I have no clue how to fix it. If someone could tell me how or if it's just not workable - either way, just need resolution. Thanks and God bless!
