Maximus 7 HERO error code 99

[Tokeegee]

I am running a system with a Core i5 4690k, an Asus Maximus vii HERO, 16GB G.Skill Ripjaws X RAM, and I was using a GTX 1060, but I've ruled that out as an issue, so I've just been hoping I can get the system running with just integrated graphics. This all started after I moved my parts from one case to another. According to the manual for this motherboard this is a "Super IO Initialization" error. Does anyone know what this means, and what I should do to fix it?

 

So far I've tried:

• Clearing CMOS (like every time I change something)
• Reseating the RAM
• Reseating the CPU
• Using a Different power supply (I went from a 500W terrible Azza PSU to a 600W Corsair 80+ Gold PSU)
• I've unplugged all of my peripherals and tried booting
• Changing the CPU cooler (I got a different error code that had to do with CPU initialization at one point)

I have no idea what to try anymore. This is the most confusing issue I've ever run into, I've been trying to fix it for hours.

Thanks for any and all responses!

So I called Asus and apparently 99 is an issue with the BIOS itself. Everywhere else online says it's a Super IO Initialization issue, and basically I wouldn't have plugged in the 4+4 EPS connector properly. I've tried 2 power supplies both the the connectors in correctly, so I am now awaiting a response form Asus support.

I tried outputting to VGA, got a proper post, now the board works normally. I have no idea why.
