I would RMA both the motherboard and the CPU. But first. Make sure you haven't accidentally shorted the motherboard to the case somewhere - this can happen if you forget to put the standoffs on the case. This is an easy enough thing to forget.
Your problem seems like OCP is kicking in.
Windows error is normal for a power failure event.
Unless you can get a stable booting on one of you prior sticks of ram....Kind of hard to pin down what's failing but it sounds like memory controller on the cpu.
Just ignore this. Your board doesn't have this feature...
Alternatively you can use Asus' bios flashback to upgrade the bios and see if this helps matters. You will need a reliable usb stick and you will need to name the bios .cap file something specific to that board ( you will need to look this up ). The bios flashback feature will work as long as the system has standby power - you don't even have to be able to post properly as far as I know.
The are detailed instructions online for the bios flashback feature - the process takes about 5 minutes or so.
Also, if you want to leave those sticks in, just keep hitting the retry button, or memory safe button.
But this. Let the system idle after it gives you a red light on your ram as you described. This will warm the sticks up a bit. Maybe a few minutes or so.
Then try hitting reset button, keep doing this until you either hate Asus or it posts. It may eventually train the memory correctly unless you have a genuine cpu issue or a short to case somewhere ( in which case you would have a shutdown for no apparent reason while idling in the bios ).
