I've had a long-time crashing issue with KSP that, until now, has baffled me. What would happen is that my screen would go blank, I'd hear Windows play an event sound, and then I had no choice but to power down my PC. This happens sporadically, most often in the VAB. It also happens in-flight, but a bit less so. Maybe because I spend more time building contraptions than flying them.
Since playing 1.3 (and stripping me of all mods), the game has totally stopped crashing for me. As I've slowly added back updated mods, the game has remained stable. Until I put back NF and started editing my contraptions again.
I've included my game log below. The crash indicates my video card ran out of memory. I'm running an NVIDIA GeForce GTX 970, which has 4 GB of RAM, at a resolution of 3840 x 2160. The exact action I was performing in the VAB, with a complex ship open, was extending and retracting one of the new photo voltaic panels to check it out.
Guess all those textures going at once is too much for my card.
