OLD SYSTEM BEFORE BREAKING:

PSU: Ace Black 120mm Fan 750W
MBoard: Gigabyte GA-970A-DS3P ATX
GPU: XFX HD 7850 Core Edition 1GB GDDR5
Processor: AMD FX-6300
RAM: Corsair 8GB DDR3 1600MHz Vengeance
-----------------------------------------------

What happened
I was on my PC playing a game and my pc instantly turned off, upon trying to turn it back on, it stopped after 1 second. The front power button LED goes off right as I turned it on, the CPU fan spins very little then stops, no GPU fan spinning, The motherboard appears to have no lights appearing either. I can't even get into the bios because theres no display.

-----------------------------------------------

As of last night, I got a new mboard and put it in, it still didnt start, so I put an old 300w psu in to test it (took out my gpu since I need more power for it, 300w isnt enough) and it turned on, didnt have my monitor handy to check for a display. Fans started and the system stayed on, so it seemed my psu kiled my board, getting new 750w psu tomorrow so my question is:

Could my psu have damaged my cpu so it wont boot my system? or would it have just killed the cpu rather than damage it?

Well since my system starts up, does that mean my cpu is fine?

well i would think a psu would just KILL the component and not just damage it, a system needs a cpu to start up and mines does, so what im asking is what is the chances it could have kiled the cpu too ?
