That sounds very strange to be honest.
I have a 460 I use as a Physx card. So no idea why you cannot use your 285.
The blue screen usually is a hardware fault, are you sure your 285 isn't faulty after its long use?
Yeah, I'm very sure on this one. It is a system hang during driver install, and it resolves by pulling the card out of the system. There were tons of people screaming about it in the nvidia forums. Especially since the installer did nothing to warn you about it ahead of time.
