Thank you for the quick reply. I have checked the event log. The crashes are logged under the System section as "critical" events, but the reports themselves contain no useful information other than "the system has rebooted without cleanly shutting down first." There are no events associated with the game under the Application section in the same time stamps of the crashes. I have only recently installed NVSR, but I'm using the following config file - https://www.nexusmods.com/newvegas/mods/66063 The crashes were still persistent when I wasn't running NVSR. I'm already running Sheson's patch. I'll try the updated libraries as well as the suggestions on memory, and the system override options, and I'll post again. Also, I'm not sure if this can be a video memory issue. On my old system, which was pretty weak compared to this one /i3, 550ti/, I've ran the same mods with the same ENB, and the same high res textures - I have never experienced system critical crashes on it.
