Motherboard or CPU failure?

Look, I’ve got a massive problem on my hands here—let me try to walk you through this from the beginning... I was just browsing the web when, out of nowhere, the screen went black. Total blackout. I didn't think it was anything major at first, so I just hit the reset button on my PC, but then—nothing. It won't boot back up. I noticed the keyboard isn't responding either—no blue light when the computer is powered on—and even the other indicators aren't blinking. To make matters worse, the three fans on my graphics card aren't spinning at all. I actually tried swapping in a different GPU, and then even tried *another* one after that, but it's the exact same story—zero signal. I attempted a CMOS reset—did nothing... I pulled the battery out and put it back in—still nothing... Tried different RAM sticks—nothing. All the fans are spinning—the CPU cooler fan and the four others in the case—but those three fans on the graphics card? Dead silence. My motherboard is an EVGA 970 gaming and I'm running an Intel Core i5-4690K

In my experience, CPUs almost never just die—it's incredibly rare. It's much more likely that your motherboard finally gave up the ghost...

Yeah, I'm leaning that way too... I think I'll just pull the board out and send it straight to the repair center, especially since it's still under warranty! I just wanted to see if anyone else was on the same page as me! - thanks!

Ran a few days back with something pretty similar, and just swapping out the PSU did the trick...
haven't really found a spare minute to sit down and double-check all the voltage rails on the old unit yet...

It’s a bit of a struggle to follow along when you cram everything into one massive wall of text like that...

I’ve also got my doubts about that power supply. It might look fine because the fans are spinning, but it could still be failing to deliver enough juice to actually run things—so maybe just grab a new PSU. You can find decent ones for around 100-$67, though... unless you feel like cracking yours open to see if some chip is fried. Usually, you’ll spot a resistor that looks like it went through a bonfire, but honestly, it isn't always obvious. Still, try another power supply; maybe scavenge one from an old rig if you're not looking to drop cash on something new.

EDIT

You mentioned the motherboard is only five months old, but what about the rest of the components?? If the other parts are still under warranty too, just take the whole thing down to a repair shop...

I’ve also got my suspicions about the power supply—it might just be failing to deliver enough juice, even if there's enough current to keep the fans spinning... so, look, just buy a new one. You can pick up a decent unit for maybe $100--$67, unless you want to actually crack the casing open to inspect the chip and see if anything looks fried. Usually, you'll spot a resistor that looks like it went through a house fire, though it isn't always obvious... regardless, test another PSU. If you don't want to shell out cash for a new one, just scavenge one from an old rig.

I have a power supply that's only 5 months old—an 80+ rated 750W unit from Corsair

By the way—found the culprit—the GPU slot was trashed, so I moved the card to a different slot and now everything works!—thanks for the help!
