Question Apparent electrical failure in my newly built PC, could use some advice based on indicator lights from motherboard

[rhizodyne]

Hi, so I thought I would ask in this community about a recent PC build of mine.

I am using some dated parts for this PC build, but they are all new. Background is that a friend of mine just had these unboxed parts on hand and decided to sell them to me as a bundle for a steal. I made a list of the parts on partspicker: https://pcpartpicker.com/list/k6k7vn

I built the machine and attached all the cabling properly, but I notice that when I turn the power on, I see both the CPU and DRAM red lights illuminate on the motherboard (Gigabyte B360 HD3) in a somewhat alternating fashion. I know for a fact that the ram cards are securely fastened in the slots. I wouldn't exactly know what is wrong with the CPU, however.

Anywho, I see the power to the machine come on for maybe 15 seconds or so, and then it just shuts off. Without my intervention it does try to reboot, although the same thing will happen.

Has anyone seen an issue like this with a PC build? Especially with both of these indicator lights flashing in alternation? I am hoping to be able to diagnose exactly where the issue is, but I don't know where to start doing that.

Thanks for any help anyone can offer.

Make it smaller.
Remove the gpu see if it makes a diff.

3200 speed memory will not be possible on that board.

I just tried this. Unfortunately no difference. I suppose at this point I suspect the issue is with the CPU or motherboard itself.

Well my RAM is 3000 MHz, and partspicker didn't indicate any compatibility issues, so I figured it would be fine. I also researched compatible RAM sticks with this board and I did see several 3200 MHz options.

Try RAM sticks, one at a time, in the appropriate slot?
