Computer help anyone?

So I ran memtest86+ over night the other day, and there were no failures, and all tests repeatedly passed.

I have been able to recreate the shutdown. It most often occurs when on the WoW login screen, or when trying to alt tab and open a new firefox window. I could see possibly that opening a new firefox window while having the game open could potentially add a great deal of load, but I'm also wondering if it could possibly be the graphics drives for my specific laptop. THere have been people with issues with the laptop and gaming.

I would like to run PC-Check, however, when I downloaded the torrent, it just gave me a bunch of .rar files all of the same size, and all seemingly with the same components within. After I download the torrent what should I do next?
