Motherboard no longer posting

[Sior]

This is a new build, originally the motherboard did post (1/25/17) & I was using the computer fine on 1/26/17. However as of yesterday I have no post, power switch leds no longer function, & a red cpu light. Everything else works fine.

 

So far I've taken the entire thing out of the case, reseated the cpu & cleared CMOS, I've looked at the motherboard pins and none of them seem to be bent. I'm not sure if it's a cpu that suddenly died, issues with the PSU, or the motherboard has a bent pin that I can't see.

 

Any suggestions?

 

Specs:

i5-6600

MSI B150 Gaming M3 ATX

2x 8GB Kingston Hyper X Fury

EVGA SuperNOVA NEX 650W 80+ Gold

EVGA GeForce GTX 1070 8GB SC

Windows 10 64bit

Did you try resitting the RAM and made sure that the motherboard power (24-Pin) and CPU Power (8pin) is seated fine?

Yes.

And you have not tried overclocking, changed anything in the BIOS settings, or did anything out of ordinary?

Did you put thermal paste on the CPU (if you didn't put the default cooler)?

Is there anyway that the CPU cooler was seated wrong and the CPU ran for a while then eventually got too hot and heat throttled to death? (or something of that nature)

I haven't messed with the BiOS yet.

Currently using default cooler until I figure out what's wrong with it, & yes there's thermal paste on it.

I'm pretty sure the cpu cooler is seated correctly, as I've reseated the cpu itself multiple times today.
