I've been trying to get this right for days now - I've been getting crashes in a couple of games since getting my laptop repaired (they replaced the motherboard); some of the crashes don't point to any informative module in Event Viewer but the latest one points to ntdll.dll while also giving an error message DXGI_ERROR_INVALID_CALL
All of my graphics drivers are up to date (I've updated and reinstalled them three times) so I believe the DXGI call to be a DirectX issue. Is there any way for me to verify or repair or reinstall DirectX to make sure that the version I'm running isn't the problem?
Or is ntdll.dll the problem? I understand this is a critical systems library in Windows. I've gotten the laptop back restored/reset, and performed another restore on top of that. Is there something else I need to do?
