For a few weeks I have been developing only in release mode. I recently switched back to debug mode and found my previously working code failed. I have narrowed down the issue but have found it is not only present in the code I was working on, but all code (test code, old projects, sample code etc) on my machine.
The problem is that when D3D10CreateDeviceAndSwapChain is called in debug mode I get an E_FAIL error code (see error box attached). I.e. the code below (taken from a Frank Luna sample) fails:
HR( D3D10CreateDeviceAndSwapChain( 0, //default adapter md3dDriverType, 0, // no software device D3D10_CREATE_DEVICE_DEBUG, D3D10_SDK_VERSION, &sd, &mSwapChain, &md3dDevice) );
However if I change the 4th argument to 0 everything works.
I can only think that either my graphics card is broken or the Direct X SDK or Direct X runtime is somehow corrupt. Has anyone got any suggestions as to what should be my next steps?
