That flag was removed when porting to the new pc.

Do you have any idea how you can get the inside information on what wen't wrong? If possible.

If useful, here's how I initialize Directx:

A quick look at your code seems to have enough security checks to catch if there's anything wrong with the device creation and setup process. I'm afraid i have no more suggestions to your problem.

The worse bug that i can actually think of is if somewhere in your code is doing a buffer overflow and overwrites your graphics device context. I'm not sure if this can be detected with the use of _CrtSetDbgFlag() and _CrtDumpMemoryLeaks() but with those security checks that you have above i doubt you're doing this mistake somewhere in your code.

I hope someone here can help you out and i'm also eager to learn what exactly is the problem with your code and its fix.

Do you think using a copy pasted DX11 SDK folder could cause this problem?

(I didn't download the sdk again... too lazy... )

I'm not sure... I don't exactly know the exact content of the SDK installer but i'm guessing besides the API it installs some additional DX runtimes in your systems folder as well. That may be a reason to have a crash like a wrong version of the runtime libraries? But then again it should cause an error message just before your app runs instead of having a weird crash.

Is the crash a BSOD?

No the crash is not a bsod, just the graphics driver crash.

It even fails when sending the shader: (Though, here it doesn't crash, but it sends an exception [ Access violation reading location 0xBAADF015. ] )

devcon->VSSetShader(pVS, 0, 0);

, and the shader is created and validated, no errors!

This is really wierd.

Ok, just tweaking, looking and stuff.

And it finally ran! (... in debug mode )

But black...

So I ran PIX, and found out that the full screen quad was being rendered, with color. So looking over the code again, the stencils weren't being restored properly.

But I guess the next goal is to make it run in Release Mode, but for now, I'm just going to play around a bit.

Just one question: Can Directx 11 with c++ corrupt the system, or cause BSOD, even if the system is healthy?

Thanks for your help!

The code itself shouldn't cause BSOD or other "enjoyable" Windows hangs and crashes...

Any crashes/hangs/BSOD/nuclear disaster/celin dion song/zombie pandemic/etc. caused by a direct3d application are related with the quality of the video drivers only; with the introduction of WDDM (since Vista), most of problems appear as driver crashes with reset to desktop (or just with some seconds of hangs without the application crash if you are lucky)...
