I shut down my computer last night. It runs 8.1 and when I shut it down I do not believe it installed updates. I came home this afternoon and tried to boot it. It boots and after I type in my PIN, shows my desktop for a few seconds. Then, my display will either turn black or a blueish grey. There is no cursor. It does this every reboot now. I can not do anything except reset when it happens.

System info:
Two GTX 760's in SLI
Two Asus monitors

Possible culprits:
1 - I have Actual Multiple Monitors trial installed. The freezing/display blanking seems to happen when the trial time left window shows up, but that may be coincidence.
2 - I heard graphics card driver updates and windows updates can clash in some way and cause a similar issue. From what I've read, a cursor is still on screen and task manager can be opened with CTRL SHIFT ESC. Neither of these work for me.
3- Virus? I have avast so I doubt it.

Anyone got any clue what's wrong and how to fix it?

note: I posted this on general support too but I bet this is probably a more proper place to post.
