BSOD gaming problem

hey everybody, new to the site here.. just had a question about something.. being a hardcore PC gamer, my gaming pc (my first one i built on my own at that) plays anything thats out now with no problem, i even enjoyed mass effect 3 (until the ending) with no problems at all. But riddle me this, why is it that when i go to play the first mass effect, out of nowhere, the game crashes and this blue screen comes on, then computer shuts down. i am stumped on this situation, being as ME3 came out this year, and i can play no problem, ME2, i can play no problem, Metro 2033.. max detail, etc.. no problem. but when i play the first ME, it crashes. here is what the little window that pops up after i reboot says:
