Oh wow. What temperature does / did your GPU get to when you play games? Other than DDO that is, since that's now crashing on startup.
BCCode 116/117 are graphics related, usually. Either drivers, or in some cases failing hardware. If you google for it you can find evidence of both driver issues and "hardware about to die" issues.
9700M is virtually identical to 9600M, which has known hardware defects. See also here:

It isn't just MacBooks that were affected, btw. If you have one of those X305 where GPU temps go up to 95-100C, as in previous linked forum post, then a slowly dying GPU may well be what you're facing.
I'm hoping this is just "DDO doesn't like your drivers", and not hardware after all. Still, better to be safe than sorry: Do you still have warranty on your laptop? I'd check temperatures and check in with Toshiba on an RMA.
