easier to test it just by putting on the cardboard box that motherboard came with to make sure it's booting properly and not getting shorted from installing in the case.
that's normally what I do when I put together a computer for friends to make sure everything works before I put too much effort into installing everything.
I will just connect a minimal amount of hardware
CPU, heatsink, memory, and graphic card, dont bother with harddrive yet.
since all you need is to make sure it can boot into bios with the ram sticks populating the right slot.
and if it works with minimal setup, slowly adding hardware. then eventually putting it back to case.
good luck on finding out what happen and maybe solve the problem.
ps: maybe also check the back of the motherboard around memory area.
if you notice anything weird, might be worth taking picture and share to Asus.
it might help
