Motherboard dead?

[Nicolaj]

So I recently bought all the parts for my new computer. I assembled the pc and first of it wouldn't start, so I cleared the cmos and that apparently helped. 

I then proceeded to install windows and CSGO.

I also installed Corsair link, and then restarted the pc. After that all the fans were going on full speed, I then anyway proceeded to open CS and loaded a map, but as soon as it loaded the pc died. Now all that happens when I try turning it on is a pling sound from the psu.

I've tried with a different psu, and running only the bare minimums without any luck.

 

Is my motherboard dead and/or can any of you help point me closer to the problem?

 

Specs:

Cpu:  Intel Core i7-6700K Skylake Processor

Cpu cooler: Corsair Hydro H100i GTX

Motherboard: MSI Z170A GAMING M3

Graphicscard: MSI GeForce GTX 970 Gaming 4GB 

Psu: Corsair RM650, 650W PSU ATX 12V V2.4, 80 Plus Gold, Modular

Ram: Corsair Vengeance LPX DDR4 2133MHz 8GB 2x4GB

Could have fried the Motherboard with the PSU.

How? And what should I do to avoid this if I get a new motherboard?
