Hi there,
I have been running a PC with the following hardware without issue since January 2014:
PSU: Corsair AX860i (power delivered to PSU via APC surge protector)
Mobo: ASUS Maximus VI Formula Z87
CPU: Intel i7-4770k
CPU cooler: Corsair H100i
RAM: Corsair Vengeance 2133MHz (2x8GB) (Red)
VGA: Gainward Phantom nVidia GTX 780Ti
Last week when trying to start up the PC, I heard a noise from the PC case. The motherboard did not beep as per usual and did not boot. The central LED on the motherboard pulsed on and off, but the Start/reset buttons were unlit.
I disconnected all peripherals, the PSU passed a self-test and paperclip test.
Putting the motherboard on its original cardboard box, I connected the CPU, cooler, RAM and power cables. In standby, the central LED lit up and pulsed, the Start button and reset button were brightly lit but then faded. The motherboard didn't boot & didn't POST. No motherboard beep, no Q-Code. The central LED remained lit, fading in and out. The Start/reset buttons were unlit and completely unresponsive.
Thinking the fault lied with the PSU, I sent that in for an RMA and received a new one. This also passed the self-test and paperclip test.
I then performed the following steps:
1. Disconnected all peripherals including GPU
2. Placed motherboard on original cardboard box
3. Cleaned sockets, RAM and Corsair H100i cooler with compressed air
4. Left RAM and H100i cooler connected
5. Connected the 24 pin power lead to the motherboard, the CPU 8&4 pin leads and a SATA lead for the pump
6. Connected the H100i 3pin to the motherboard and radiator 3pin fan to the motherboard
The same problem occurs - the central led pulses, the start/reset buttons fade out from brightly lit to unlit and are unresponsive. This is with two different PSUs. The issue still occurs even with the RAM disconnected.
Does anyone know of a solution or is this a clear-cut RMA case? Unfortunately I can't see any blown caps on the motherboard as it has some sort of armor on it. I've followed the ""No POST", "system won't boot", and "no video output" troubleshooting checklist"".
