If neither FRAPS not OBS work on your PC, maybe look into what's wrong with your PC, both of these programs are used, and have been used, by a really large amount of people. Neither of them working properly on your PC only means there's something up with it.

For what it’s worth, XSplit can record locally, the same way OBS can (you just wont get 60fps without paying for a subscription), so if you insist OBS crashes, just go back to using XSplit and record locally, not stream.
