DirectX Keeps Crashing While Playing FFXIV, Please Help!

[Rainesong]

My PC is getting worked on, so for the time being I am using my girlfriend's work laptop. Sometimes I can run FFXIV smoothly on it for hours, sometimes only for minutes, but eventually FFXIV crashes, and the infamous error message pops up: "Unable to detect Direct X device." I have read tons of threads and tried a ton of options but nothing seems to work. Lowering the game settings to the absoulate minimun seems to increase the average amount of time I can stay on, but isn't 100% effective (and if you've ever run the game on the lowest settings, you know it's headache-inducing horrible).

The laptop has 2 display adapters:
Intel(R) HD Graphics
NVIDIA GeForce GT 420M

I emailed SE support, and they said since they don't support the Intel(R) HD Graphics, I'm basically S.O.L. Since the game runs flawlessly on standard settings until DirectX crashes, I have a hard time believing there's nothing I can do to remedy the situation.

The drivers are up to date. DirectX is up to date (for better or for worse). I have uninstalled an reinstalled FFXIV and the display drivers, but the problem persists. I run the game on Windows 7. Does anybody have any advice for me, or am I just basically screwed since the Intel card isn't supported? Could I set the NVIDIA card as the primary adapter? I don't really know how that works, but FFXIV wouldn't even start when I disabled the Intel card.

Thank you for any help!

Can't disable the Intel graphic chipset in the bios or something? No idea how those dual-graphic chipset laptop work.

well this thread makes me sad, i get that message fairly often too when my game crashes

Could it be with how the two GPUs handle the processing? I'm not sure exactly how to explain this, but on one desktop with a GTX460, every time I minimize the game it would give that message, but with my Radeon cards it won't.
