I was sitting and grinding internet poker when my laptop blue screened and rebooted. However on reboot it told me my boot image was corrupt and then the screen went black and has remained black. Laptop is a Toshiba satellite L650-st3n01x and is not even 3 months old.

How to fix?
More importantly what is the likelihood I'm going to lose my harddrive because if so ill just /life right now
Also any idea on cost to get this fixed. Id look myself but am typing this all on a phone. It's a bitch.
