The blue screen of death (BSOD) is synonymous with the Windows operating system. How many times have you been in the middle of installing some new awesome game when the blue screen appears, out of nowhere. So what do you do?
If you have the cash you get the nice implentation of freeBSD and linux (aka OSX) or you get the poor mans Linux box and just install ubuntu on your now dead machine. It can be sad and really embarrassing to get the BSOD. Especially in these high profile instances.
