Well, I have exhausted all the suggestions I have found so far, including the checklist sticky.

My pc has recently began just randomly turning off. No BSOD or anything, just a hard shutdown. Sometimes while gaming, sometimes while just idling. When I try to reboot it, all the fans, light, had, gpu will all seemingly power on. No beeps are heard, and before anything will come on the monitor, it will shut down again.

Here is what I have tried:

-switched out PSU
-switched out the CPU
-reset the BIOS battery
-removed the RAM down to 1 and tried many different sticks and variations
- tried a different HDD
- powered on and pulled the power switch plug to eliminate stuck power button
- tried other power cables and wall outlets


System specs:
AMD fx 9590 8-core stock speed
GIGABYTE FX-990-UD3
SLI gtx980 MSIs
8GB gskill ripjaws 1330 RAM
8GB crucial ballistix 1330 RAM
3TB western digital HDD (I know :( )
Corsair RM1000W modular power supply

Do you have an 'internal' speaker connected to the motherboard? They are designed to enable the motherboard to output one or more beeps if there is a problem with a computer. The miniture speaker comes with most modern cases. If you do not have one, plug a pair of headphones into a headphone jack on your computer (some motherboards can output a beep through the 3.5mm jack). Then turn it on. Do your headphones play a beep? If so you can easily diagnose the problem from there on. That's all I can think of. Good luck. I hope you get that puppy working!

Also, try removing one of your GTX 980s from the PCI-E slot. It's unlikely, however both of them could be drawing a strenuous amount of power from a possibly damaged rail on the PSU.
