Windows 7 Unexpected crash(BlueScreen) Everytime i open BitTorrent

So, this is how it goes.

I am downloading an eight-gigabyte file on BitTorrent while suddenly, the screen flashes and restarts. This is ocassionally happening while im gonna continue my download. What I'm doing to avoid this, I am closing BitTorrent. But, I really need to continue the download. As I remember, this things started to happen when i suddenly unplugged my laptop, and when I plugged it in and used it, It required Diskchk.

Here's the problem log (?)
