While I had the radiator out I closely checked the eight pin CPU power connector on the MoBo. On this board there are issues with heat damage reported, but I found everything to be fine on the old power supply. I triple checked all of the main power connections i.e. MoBO, CPU, GPU and externals. Then I went around and triple checked every connection on the MoBp to the various fans, headers, SATA etc. I hyper cleaned the entire box including all of the cables and shielded cables etc., then I plugged in the main power supply.
Here's the funny part... I was re-installing the external bling plastic to the front and top of the unit. As I was snapping down the top piece, I depressed the start button by accident.
The machine powered up!
I didn't have the screen connected, but by sound I could hear the machine searching for it's boot sequence. At this point I shut the machine down because I had removed the CPU heat sink during the inspection and need to clean the CPU & heat sink and re-apply thermal paste. I did, however, hook up the screen and attempt a short boot sequence to enter the BIOS. The monitor was not receiving any data via the HDMI 3 cable, and showed no connection. I checked the monitor to make sure it was pointed to HDMI 3, it was.
I thought it may be the GPU, so I switched out the GTX 1080 TI to my GTX 780 TI. Same result with both cards, so I put the 1080 back into the tower.
With my limited expertise I am leaning to the conclusion that it is the MoBo that has failed. All of the components including the video cards are spooling up, fans turning and lights blinking...just no output to the monitor.
At this point I'm still looking at the system update/rebuild.
