[SOLVED] No signal to monitors

Hey everyone, I'm having some computer issues. Last night, my computer stopped sending signals to two of my monitors when I get it loaded up, but it recognizes that all three monitors are there at startup and when I check if there are monitors in the NVIDIA control panel, it sends a signal to at least one of the other monitor during startup, and the other monitors will occasionally wake up but then go to sleep saying there is no signal. Then this morning while I was trying to troubleshoot, it quit sending a signal to the third monitor.

Here's what I've tried:

1. Restarting and killing the power for a hard reset (including holding down the power button while the PSU is switched off),

2. Swapping the graphic cards around to the other slot,

3. Switching between a surround desktop and three individual monitors

4. Updating drivers.

5. Pulling the graphics cards and connected directly to the motherboard, and the integrated graphics are working fine.

6. One suggestion I found was to pull the RAM chips, reinsert them

7. Testing both graphics cards individually. Both cards will only display to one of the three monitors and can't detect the other two at all. Neither will allow me to adjust the resolution of the display.

Any idea what might be the problem?

My set-up:
MB: ASUS Z170-A
CPU: Intel i7 6700K (liquid cooled)
RAM: 32 Gb
Corsair
Graphics: 2x EVGA GTX GeForce 1070 w/ SLI Bridge PSU: Corsair
RM750
Memory: Samsung 500 Gb SSD, WD 2 Tb HD
Case: Fractal Design
Monitors: 3x
ASUS VG248QE
VR: Oculus Rift

So, it turns out it was a monitor issue. When I first started having trouble last night, the middle monitor was the first to not turn on, then the second monitor went out after that. I was just playing around between trying suggestions people were sending me; when I unplugged the two monitors that were not turning on from the computer, and plugged the second one in, that one worked fine, but when I plugged the first monitor in, it seems to know to wake up, but then say there is no signal (the second monitor stayed on though). I've tried switching DP cords too, but the middle monitor still wasn't working. So, I unplugged that middle one from the wall, waited a bit, and plugged it back in. Now all three monitors are working again.
