    First I'd boot a LiveCD to make sure it's not a coincidental hardware failure.

    Changing a HDD from mbr to GPT can in no way do anything to your display. It looks like your video chip has died. Which video chip does this laptop have? Is your system able to POST, ie do you see anything on the screen when you power it on?

    I would suspect a heat issue, the lid-closed switch, or the cable from the chassis to the display before suspecting the GPU. Make sure it's clean and let it cool off before trying again.

    I would unplug it, remove the battery, clean it, check the lid switch and toggle it a few times directly or indirectly by opening closing the lid, plug everything back in and try to get to the BIOS.

    If you still don't have a display, toggle the display function (internal/external/both, usually Fn key + another key); if that doesn't work, try an external display to isolate the problem between the computer itself and the display.
