Hackintosh all of the sudden stops booting after being very slow.

Hello. I haven't been here for a long time because of how well my Hackintosh has been running since I got it basically running 100% like a real Mac (only issue was sleep mode but I didn't feel like spending time to fix it since I don't use it much). Anyways, starting this morning, my Hackintosh started freezing up for a few seconds, then unfreezing, only to freeze again a couple seconds later. I tried deleting a few apps and documents (no system files), rebooting a few times, and nothing really worked. It seemed like it would start whenever I reopened Pages, but maybe that is just a coincidence. Anyways, after rebooting again, I all of the sudden couldn't boot at all from macOS. I would get a solid black screen with the mouse flashing in the top left. When booting in verbose mode, it would display the text in the image below, mouse would flicker, display the text, and then the process repeats. Booting in safe mode didn't fix it either.

Any help or suggestions would be appreciated.

CPU: i5 4690k
MB: MSI Z97 PC MATE
GPU: EVGA GTX 960
Running from SSD, duel booted macOS Sierra and Windows 10.
Other specs probably don't matter.

I would suggest troubleshooting for hardware causes of what you are seeing--power supply, drive failure, heat, etc.
It never hurts to open the case and make sure everything is seated/connected and the CPU cooler is working.
If you dual boot obviously if the system runs stably in Windows it is not hardware. If you do not dual boot you can see if the system will run stably on a Linux distro from DVD or USB.
If you cannot stably boot into anything I would suspect the power supply. If you do not know how to troubleshoot that you will need to consult a local repair shop.
If you eliminate hardware causes then I hope you have a clone of when your installation was stable. When faced with the inexplicable reverting to a prior stable state can cure many ills in the easiest possible way.
Which reminds me---I need to run Superduper!

Thanks. It isn't a hardware problem, because I'm typing this from Windows 10 right now. Guess it won't hurt to reinstall macOS. Thank you for mentioning that "SuperDuper!" software btw, it looks really good and I will probably use it if I can get back into my installation or when I do a reinstall.
