If you can borrow a stick or a pair of DDR4 rams from your friends and tested them on your board then you can rule out if the board or the ram kit(Corsair) is the culprit since a lot of people have been complaining about the DRAM LED being lit up in spite of the system either powering up or when trying to power up essentially meaning a dead/pseudo bricked motherboard. Which slots have you populated on your motherboard? Per your
motherboard manual you should populate DIMM Slot A2 if using only one ram and DIMM Slots A2 and B2 when using a Dual channel kit.
Have a go with pressing on the MemOK! button and see if any changes take place. One other thing you could do is remove the motherboard battery and replace it after 15 minutes and see if the system boots up. Failing that, have you also tried bread boarding your system with only the bare minimum to see if there is a grounding issue preventing you from a system power up?
It'd help us further if we knew of your full system's specs.
