I had just updated my sig rig the night before the problem. The next day I played New Vegas for about 30 minutes when it crashed and after a restart I kept getting aface with a different error each time I tried to boot. I did a system restore to one week previous and still had the same error. I attempted all built in repair options including deleting all apps and still had no luck. I then tried to repair with my windows 8.1 CD and a friend's windows 10 flash drive which didn't work. I then bought another solid state and disconnected my old one. When I tried to install windows 8.1 on the new SSD I got the same error part way through installation. I ran memtest86+ overnight with no errors. I'm kinda lost at this point. I've got nothing at this point, any ideas?
