CPU light rears it's ugly face yet again

[CodePurple]

Solid Cpu light after Installing a few more hard drives,
B350 AM4
Ryzen 7 1700x
32g ddr4 leorice
In a Cm storm case
with an Ax 760 psu
Firslty I had plugged in a new modular cable to the psu, for some extra sata, and the cpu fan would only spin once and then nothing, I unplugged that and now everything spins up but cpu light stays on,
the cable I plugged in didn't say ax760 only, maybe that did something? And what should I do next?

Check your mobo make sure it is screwed on properly on the case mounting pegs.
Please make sure it is not too tight or too light where it moves around easily.
That would make the cpu lights on the mobo come on.
Just to clarify specify "exactly" how many drives you have hooked up.
Also tell us what mobo brand you have by chance ?
You telling us B350 could be anything and not getting more at the root of the issue.

If its a MSI brand read this towards the bottom before you reply back:

I know this is your first build and not trying to ruin your magic here..
However that ram and the name of it is not worth it.
I ship it back for a different brand replacement within the allotted return time. :/
