flashing blue power light - reboots

[randyz]

I'm working on an Acer E5-511P-C9BM, I've tried most everything that people have listed on here. The power (blue) will come on, along with the fan, momentarily and then go off. It will continually cycle this way. I've pulled the memory, hard drive, battery, hard reset the system as indicated in other threads and tried external monitors. No success.....could this be a bad motherboard?

It is possible (and likely) that the motherboard is the issue.
