Dragon Age: Origins doesn't start

Hello!

When I try to start the game, it just quickly shows the splash screen and then crashes without opening any more windows or anything. There is no error message. I do own the origin and the gog.com version, both versions don't work.

Here are the things I already tried:

- Installed new graphic drivers (and removed the old ones completely with DDU)

- Reinstalled nvidia physix

- Installed legacy nvidia physix

- Installed some older nvidia physix version

- Re-installed Microsoft Visuial C++ Runtime (2005)

- Re-installed directx9, also with the bundled version of DA:O

- Killed background applications

- Patched the DaOrigins.exe with the 4GB Ram Patch

- Setup a shortcut to run DA:O with processor affinity

- Compatibility Modes (Windows XP SP3, Windows 8)

- Running DA:O as Admin

- Disabling all Sound

- Running on minimal settings

- Running in windowed mode

- Disabled any overlays (nvidia experience, origin when using the origin version)

I honestly don't feel like reinstalling windows though just to run one game. So I didn't try that. My System Specs are in the attached DxDiag. You can also see an error message there when running DA:O, it looks like the following:

Fehlerbucket 1345926085282786522, Typ 1
Ereignisname: APPCRASH
Antwort: Nicht verfügbar
CAB-Datei-ID: 0

Problemsignatur:
P1: DAOrigins.exe
P2: 1.5.13263.0
P3: 4eb19d53
P4: nvcuda.dll
P5: 25.21.14.1735
P6: 5c0f5706
P7: c0000005
P8: 0030a65f
P9:
P10:

It specifically names the nvcuda.dll, but after doing some research it looks like a very common error signature in all kind of games crashing.

I really would appreciate any ideas! Thanks 🙂
