Im see this error before - DXGI_ERROR_DEVICE REMOVED 0x887a0006.
Usually its related with NVIDIA and Intel GMA driver. On My Alienware m17xR4 sometimes its happends and with non-unreal DirectX applications.
Guess its not a Unreal issue and required NVIDIA/Intel fix. i5 have iGPU (GMA), so its can be this issue.
