Windows 7: BSOD - windows 7 starter - PLEASE HELP ME

1. I tried to download the file in the BSOD Posting Instructions, but Norton Sonar said it was corrupted, and subsequently deleted it.

2. My computer keeps crashing on me (This only happens to me when I'm in my office at work. My computer NEVER crashes on me when I'm in other rooms - different access points?? - nor does it crash when at home, in the library, etc.):

THANK YOU!!!
