Windows 7 - blue screen

Randomly throughout the day my computer will suddenly blue screen. It's already done it twice today that I know of. I don't know how to capture what's on the blue screen, but this is what my computer gives me:

I just got this computer about a month ago. I loaded some programs onto it when I first got it and everything seemed to be fine. Then whenever I moved back to school (two weeks ago) it started doing the blue screen error. Sometimes it will do it 3-4 times a day and sometimes it will go a few days without doing it at all.

Hello,

Did you overclock your PC?

They're most probably due to faulty/incompatible RAM. Please perform these memory tests:

disable the automatic restart after system failure
goto control panel/system/Advanced system setting,
click the advanced tab
under Startup and Recovery click setting
uncheck Automatically restart. OK

Now when it blue Screens you can get the Stop error and research it.
