Reopened a day-old save in normal mode, not safe mode and walked around ranch for about ten minutes. Accidentally hit Alt at same time as SPACE, several seconds later the video broke apart into large pixels and green blocks. Tried to close out of game when windows crashed. Boot screen showed same green blocks twice (will get pictures when at another computer) Could not restart into normal mode, blue screen.
Crash Report looked like this:
Able to run Windows in Safe Mode with networking, updated video drivers, but I have a feeling I will need to reinstall windows to fix this.
