This is my first build and I am having difficulty booting up the system. It starts off that everything takes off as normal for about 1/2 a second and then it goes into automatic shutdown. Afterward it tries to boot again but does the same thing. I've tried swapping out PSUs but the same thing happened. Here are the specs.
I would reference the bios against the CPU, make sure the bios microcode is up to date.
I would do an out of case build, to be sure your not shorting something.
Also make sure all the needed power connections are proper.
