I've been working on fixing this notebook for 2 weeks now. Finally i just went and got a new hard drive, and after installing a downloaded iso windows7, it installed fine and worked great.....until I tried to shut it down. Then it froze where it says: "Shutting down". Thinking it was a first-time fluke, I powered off, then restarted it. It worked fine again until getting to the same point in "Shutting down" where it froze as before.
