As far as I know TBSOD can be caused many different ways, both hardware and software related, so that's probably why you're not getting a single answer. The screen itself should give you some sort of indication as to the problem, but you'll most likely have no time to read it before the screen crashes, and/or you won't be able to understand what it means.
I myself haven't really fallen victim to many, and most were when I was real young and non-computer-savvy, so I didn't really deal with them (even now I don't own my own PC so I don't take care of them completely). However as Roxas said you should probably see if some of your hardware is loose or dusty if it happens.
Basically, the most you can do to prevent them is just take care of your PC as much as possible. Keep it clean, run virus/registry scans, defragment occasionally, etc. Hope that helps!
