BSOD (possibly when playing video games)

[Rye Bread]

Hello everyone. I hope someone can help me.

Windows 7 x64
Full retail version. Original OS.

Brand new system less than 1 week old.
OS was also installed less than 1 week ago.

As far as I can tell, I get BSOD'd only when playing video games. (Steam is also active.)

Drivers are all up to date (probably). I also have avast! despite perfmon telling me I don't have an antivirus program.

Zipped documents to "desktop.zip."

Thank you.

Edit: I performed memory checks and they all passed. I also noticed that the file dumps have the same bug check code, and I believe I read somewhere that repeating bug check codes do not usually point to hardware problems. Is this true?

Just an update:

As far as I can tell, it appears to be Steam related. I have been playing other games not logged in on steam and have yet to have a BSOD. (League of legends, Starcraft II)

Is anyone familiar with a steam related issue that could be causing this?

Bumping this thread as I have yet to come across a fix.
