I'm having some problems with OFP (Operation Flashpoint).  I was playing it merrily, no problem, and then it crashed, when I try to start it up again, I get the following message-
---
Cannot create 3Ddevice:
  Adapter 0 (NVIDIA GeForce FX 5200) Fullscreen
  Resolution 1024x768, format X8R8G8B8/D24S8, refresh 75 Hz
  Error D3DERR_NOTAVAILABLE
---
This is very strange, because it just crashed out of nowhere.  It should be noted that I was having problems with it freezing up for 20 seconds, playing fine for 3 minutes, freezing for 20 seconds, so on and so forth.

Any ideas?  A speey response would be appreciated

UPDATE:  After a reboot, I was able to play fine for about 15 minutes before it started freezing again, and then promptly crashed. I got the same error message when I tried to start it again.  It would appear as though something happens while I'm playing it.

If no one here knows (thought I'd give good ole SimV a try first), could you please direct to a hardcore hardware forum?

RE-UPDATE:  It should also be noted that I recently installed new vid drivers.... do I need to manually uninstall the old ones?

Thanks for the reply... this seems like it might be much more helpful than what Codemasters sent me.

One thing-I have two "driver" related things on the add/remove software, NVIDIA Drivers and NVIDIA Display drivers.  Do I just remove both?

Thanks for the quick reply, I'm on it
