1: Analog Input cannot display this video mode

Okay, so I looked for some answers involving this but nothing seems to quite fit my issue. I woke up this morning, turned on my computer and after some loading it stopped just short of the log in screen and told me that it couldn't display the video mode.

Now, I'm not sure what's happened here. I haven't done anything to the computer recently, and currently I'm running my computer in safe mode, which works. I tried to hook another monitor, but they both have the same issue. Nothing major has been done to this computer, and I don't even think that anything was installed. I was using it last night, got off, went to bed and then woke up to this.

Any help would be greatly appreciated.
