I am having some serious issues with my Aorus Pro board. I originally ran a Gigabyte Z270-HD3, i7 7700K (non-OC, completely stock), Noctua NH-D15, 4x Corsair 8GB DIMMs, relatively cheap but decent Enermax PSU, and some other bits and pieces. This worked fine. Wanting to upgrade the case to something a bit more flashy, I decided to bite the bullet and go all the way on the 'flashy bits'. So... Ordered the Z390 Aorus Pro, 4x Corsair Vengeance 8GB DDR4 3200MHz RGB sticks and proceeded to build my system. I've built more than a few systems in my time, so I did not expect any issues.. However the Aorus will not start and has me stumped. The CPU diagnostics led flickers for a moment, lights on the memory flashes on for a moment, then everything dies again. No beeps (if I connect a speaker), nothing. I've pulled -everything- from the case, testing it now on a test bench: just board, 2 memory sticks, the i7 7700k, the cooler, and nothing else. Same thing. I've peeked at all the pins on the CPU socket: no bent ones as far as I can see. Underside of the CPU is clean (no stray cooling paste or anything). Putting everything back (including the new memory) into the Z270-HD3 works like a charm. I've reset the CMOS, I've made sure the 8-pin 12v connector is connected. I've even hotwired another ATX power supply so I could power both the 8-pin AND the 4-pin 12v (though as far as I understood that shouldn't be necessary if you don't plan to overclock). I've run out of ideas... Anyone able to give me a little nudge?
