Windows won’t start after it crashed because of AutoHotkey

So my windows won’t launch after a presumably bad AHK script. It’s for a game I play, and the script is extremely simple, right click mouse will trigger key 8, mouse wheel up/down trigger 9/0. But when I tested it in game, the screen went black and I couldn’t ctrl+alt+del so I had to force restart it. And since then the windows won’t launch (except for safe mode). After the windows logo it just went black. Startup repair can’t fix it, I can’t use system restore because there’s no restore point. And suddenly my screen have this weird glitches. [Example 1](http://oi67.tinypic.com/msf3fd.jpg), [Example 2](http://oi65.tinypic.com/10pbqfn.jpg), [Example 3](http://oi65.tinypic.com/orrv5z.jpg). Is this a hard drive failure? I don’t understand a lot about computer so I appreciate any kind of help.

Edit: its Windows 7.
