Well, after I talked about the Blue Screen of Death during the Olympics, arstechnica mentioned it.
The more important point though, is the discussion in the comments.
Here are the theories as to why the BSOD happened:
1) Hard disk failure
2) Pirated copy of Windows with not all the right updates
3) Air particles due to the pollution in Beijing
4) Bad configuration of Windows (at least failing to tell it to restart after crashing)
5) Not using Vista
6) Failing to use a Mac
7) Failing to use Linux
8) An act of terrorism, deliberately trying to embarrass China
