I have a Lenovo G530, Windows 7, only a couple months old. It used to shut down within 15 seconds. 2 weeks ago it started acting up - it will not shut down - it will stay at the shutdown screen for 10-45 minutes, and eventually restart itself, and then when I try to shut it down after that - it will shut down. But then the problem repeats itself. I tried a system restore - it shut down once properly. And then after that it wouldn't shut down again. So lately I have just been hibernating it. But 2 days ago I decided to try to shut down again, and I got the blue screen! Any help would be apppreciated!
