GTX 780 Smoking?

I have an MSI GTX 780 Twin Frozr, and I've had it for a half a month over a year. A few months ago my computer began randomly BSODing and shutting off. The bluescreen viewer always gave a leading suspicion to something nvidia related. So I would roll back drivers and download an older one. It worked for a while, then it happened again, except this time the computer would not turn on. If I unplugged my GPU and HDD/SSD the computer would turn on but the PSU would be abnormally loud. I went with the idea that my EVGA PSU is on it's dying days, so I replaced it with a Corsair equivalent, 750W. I did this December 5th, installed new PSU and would decide to later RMA the EVGA if possible. The computer worked, no issues at all, until now. Yesterday night I was playing a video game and the computer just shut off, no lights on inside nothing at all. I flipped the PSU switch twice and pressed the power button. The lights turned on and fans spun up for about half a second, then back to darkness. There was an electrical burning smells so I removed the GPU and tried to power up the computer and it worked. When replacing the GPU after a quick dusting with compressed air canister, I powered up the computer to see a white and red flash of light from the GPU and smoke. I turned it off right away and took out the GPU. It left a small burn mark on my MOBO in what seems to be some sort of plastic or material that cases something important. The GPU smells like electrical burning and I've packed it up for RMA. 

tl;dr
780 started smoking and burning.

Can anyone think of something that might cause this besides my GPU?
All replies appreciated, not having a GPU will be tough for a bit..

I think something in the VRC just gave out.

Maybe a MOSFET or something blew out. I had one blow on my 6570 and it was just a jet of smoke rocketing out of it,

Could you elaborate on that a bit?

VRC means Voltage Regulation Circuitry. It's what converts the 12V to something the card uses. I had it happen on my 660 Ti. A tiny capacitor next to a transistor blew on it.

I should just RMA it and hope for the best?

Not too sure how MSI's turn around it.

Ouch. Can you post a pic of the damaged part on the motherboard? Maybe we can tell you what it is and if you can save it.

 

The motherboard is 100% fine. Burn mark was wiped away by brush of a finger and isn't noticeable without looking very closely.

The mark went directly over this box with the dragon decal, it was horizontal to the graphics card. Where one of the pipes were. I'm assuming the mark was from the smoke or something.

EDIT: I think this box is just a plastic or carbon to cover something important. So far the computer is running fine with the GPU no longer in the system. I've just updated my intel graphics drivers.

That's the heatsink that covers the chipset. One of the most important places on your motherboard ^^ damage to what's under that would probably be fatal.

Don't ask to ask, just ask... please 🤨

It seems to be running fine.

Been playing Hearthstone and running a few livestreams in the back.

I'm just hating the fact that my PSU may not have been the issue and I spent  $110 on a new PSU for nothing.

Could the graphics card been what was shutting my computer down this whole time? Like it had been slowly becoming more and more destroyed.
