Question My mob isn’t allowing dual channel when I have 4 dim slots.

When I put my ram in dim slots 2 and 4 my pc does not boot up and my led fans starts to flicker. 1 and 3 also don’t work and think the motherboard has an issue. I recently just bought everything for a upgrade and when I installed it, my pc won’t boot up in dual channel but only single channel. Also my cpu is being used up to almost 100% and including my ram. The cpu idles at like 7-20 percent and feel it should be idle at about 1-5percent. Someone please save me from this problem.

Specs:
Intel core i5 9400f 2.9 ghz
Team Vulcan DDR4 2400 2x8 gbs ram
Zotac 1050 ti 3gbs
B365m pro4
Arctic freezer 7 pro
Evga 430w 80 plus
