I get hard crashes (requiring a restart) fairly often (once every hour and a half or so). Most of the time it's when i fast travel, enter a building, go through a door, etc. I do get hard crashes when i'm just walking around, but those happen less often. I also get some soft crashes (Fallout.NV.exe has stopped working, then it closes, not requiring a full PC restart). I've been using the 4GB and NVSE. Here is my load order:
