Following up, I think the crashes have been related to drivers for my Turtlebeach PX5 headset. After switching to a standard usb headset I haven't had any further problems.

Any suggestions as to what I could try to resolve this as the game isn't really playable now? I've had the error popup or return to desktop on most sessions. I have noticed that the games stalls or stutters slightly before it crashes.

As a data point, I've been playing x-plane over three screens and the graphic card gets a lot hotter than in Argo, but no crashes or other problems in x-plane.

The verify ran OK. The next game just returned to the desktop though. I though it might be that I've added a third screen but I've just played with only one screen connected and got dumped back to the desktop again.

I'm pretty sure I've had the error in other scenarios.
