MSI Z170A Gaming Pro Carbon
Corsair CMK16GX4M2B3000C15 Vengeance LPX 16 GB DDR4 3000 MHz (2 x 8GB sticks)
Corsair RM750x 750W
Asus ROG Strix GeForce STRIX-GTX1080-A8G-GAMING 8 GB
Intel Core i7-7700K 4.2 GHz
Putting together this new build for a friend and I've hit a problem which really has me stumped.
I've worked through the checklist for testing new builds already, and it hasn't shed any light insofar. I've also tried some more generic fixes like resetting the CMOS and reseating all the components.
I've checked the compatibility of all the components against the mobo and it all seems fine - though the motherboard was RMA'd at my friend's request - the problem has persisted.
When I power the PC on, everything starts up fine,though I have no USB/video input. The DRAM LED on the mobo comes on for a few seconds, then turns off. After it goes off, everything stays running for a few more seconds, and then I hear the CPU fan spinning down, although it doesn't seem like the system completely loses power, as the LEDs on the GPU stay pulsating as normal (I'm not sure if this is just because they're retaining power longer).
I've tested both sticks of RAM individually in each slot, and the only way to get the PC to stay "running" is to have the RAM in a "bad" slot (E.G., putting it in the third slot when the manual specifies the second). However, doing that doesn't give me video/USB.
I'm at a loss, as the RAM is detected when it's in the right slots, but the PC won't stay powered on with it in, and it seems unlikely that both sticks would be faulty, though this is the conclusion I'm coming to.
Would very much appreciate any help, as I'd rather not have to RMA the RAM if at all possible.
Thanks in advance!
