I just got done building my pc and when I tried turning it on all the fans and the motherboard did go onn but I didn't get a signal and there is a red light next to dram. The mb is mounted in the case with 3 standoffs because there were only 3 with the case but I don't think that is the problem.My parts are:
I5 7600k
Msi radeon rx 480 8gb
Msi z170 sli plus
Samsung evo 850 250gb
Be quiet! Pure rock slim
Bitfenix neos zwart/zwart
Cooler master GM G550M
Corsair ddr4 vengeance LPX 2x 8GB 3000 c15.
Edit:just tried it with 1 ram slot the same happened
