Thanks Nate. I updated the BIOS today, didn't work. I noticed that the CPU fan doesn't start up, but the case fans do?

I'm having nearly the exact same problem. No problems for two months and then hit a key to take it out of sleep mode and nothing. Opened the case up and all it says is "00". Tryed the RAM troubleshooting. Nothing. Same i7-4790K CPU and very similar ...
