GTX 780 Bricked by GTAV - Probably dead but any suggestions?

[Gypopotamus]

Ok so this is gonna be quite the long story, so if you don't wanna read the whole thing, the summary is that my 2nd GTX 780 (I have 2 in SLI, and it's the one I don't have monitors plugged into) is dead. Attached is a screenshot of various programs showing how it's fucked.

Right now for a story.

The other night I was playing GTA, when I noticed my frame-rate was very low. I tabbed out to look at what the issue was, and noticed SLI had been disabled. This was odd, because I hadn't disabled it, nor had I recently updated my drivers or tinkered with it in any way. Regardless, I enabled it and relaunched GTA (which I obviously closed before enabling SLI). I got into the game, joined my friend and started playing at my lovely new actually playable frame-rate for about 2-3 mins. Then, all of a sudden the game crashed.
I was fairly certain it was a driver crash, as my PC was still on, the game had frozen, and the audio was doing the usual stuttery/repeating bollocks that it does when a driver crashes. I tried tabbing out, I tried ctrl-alt-delete, and I tried alt-f4 but nothing worked. So, the only thing I could do was hard reboot my PC. I pressed the power button to see if it would safely turn off, but it didn't, so I held it until it manually turned off. Then after a few seconds, I pressed the power button again to reboot the PC. It posted, showing the Asus logo, and then it got to the Asus logo with the spinning windows loading thingy, showing that windows was loading.
However, after that screen disappeared rather than the screen going black and then it showing the log-on screen, it went black, my keyboard LEDs turned off, and then it just stuck there. My monitor back-light was on, my PC was on and the fans were at a normal speed for booting up. I waited for a good 2 minutes before having to hard reboot again. I tried loading up the PC a good dozen times, trying turning it off at the plug and waiting, trying booting windows from the UEFI BIOS, but nothing I did worked.
I decided to insert my Windows USB and try repairing my install. I tried start-up repair but nothing changed. Then I tried restoring back to a recent date (it was about 1 week prior and it uninstalled a couple of Steam games and a Uplay update), but it failed and still wouldn't load into Windows. I then went to Command Prompt and enabled legacy boot mode using the command "bcdedit /set "{current}" bootmenupolicy legacy". I rebooted and suddenly it worked, even though it never showed the boot menu and I didn't use safe mode. I logged on, and when I got into Windows, it said my system restore had been successful. Strange.
Sure enough my Uplay update was gone (in fact Uplay would no longer open which was annoying), but everything else seemed fine. Then when I opened up the Nvidia Control Panel to check if SLI was working, I saw only 1 GPU. Fuck. The I opened Device Manager and saw code 43 on that GPU. Double fuck.
I rebooted. Didn't work. I reinstalled the drivers. Didn't work. I took it out and put it back in. Didn't work. I swapped the slots and plugged my monitors into the dead card, and there was no signal. I tried it in my flatmate's PC alone and it booted! Although it was at 640x480 and Nvidia Control Panel wouldn't open. We reinstalled the drivers and the screen went black with purple lines on it before showing no signal again. Put it back in my PC with no second card. Still no signal. Fuck.
So then I put it all back the the original state of things and booted into Windows. I downloaded nvFlash and a bios from the techpowerup database (the one for my exact card). I flashed it and rebooted but nothing changed. I tried again with a different version for the same card and still nothing changed. Then, I downloaded one for a different card (an EVGA one) and flashed it with that. I rebooted and suddenly both device manager and Nvidia Control Panel showed the card just fine, except in Nvidia Control Panel, I couldn't enable SLI. I went through the previous bout of testing again, and still the same results even with this seemingly working BIOS.
Anyway, after a lot of flashing backwards and forwards I removed the card and replaced the thermal paste. Then 2 days later put it back in for another go. Still the same story. And now here we are.

Attached is a screenshot of GPU-Z, Nvidia Control Panel and Device Manager, all with the problems highlighted. That is with the proper BIOS on the card, and everything in its original configuration. 

Any suggestions are more than welcome, but I realise that the card is most likely dead.

Here are my full system specs:

ZOTAC GTX 780 AMP Edition @ Stock - Working
MSI GTX 780 Gaming OC @ Stock - Dead
Intel i5 2500k @4.5ghz and 1.45v (yes I know that's a lot of volts but the temps are fine and it's been at it for nearly 3 years so it's pretty stable)
Asus P8Z77-V Pro Motherboard
16GB of Corsair Vengence 1600mhz memory
Samsung 840 SSD 250GB
2TB WD Black HDD
Corsair AX760 PSU (Yes I realise that's on the limit but it's been fine for a year and I don't get any problems unless I OC the GPUs. Could be the cause conceivably?)
Asus Xonar DG Soundcard
AverMedia Live Gamer HD Lite
TP-LINK Archer T9E AC1900 (Newest component - only a week old)

Windows 10 upgraded from a clean install of Windows 8.1.
Latest Nvidia drivers.
All up to date and un-fucked with.

Anyway, that's my story, and I hope you enjoyed. I guess what I really want is someone to come up with a cause so I (and other people) can avoid it.

Thanks,
Joe

Contact MSI if it's not out of warranty and RMA it.

long story short you had a faulty card and you were SoL, this could have happened while you were doing anything else, that was your luck.

Out of warranty, especially after I removed the cooler 6 months ago to replace the thermal paste that was completely gone causing my temps to rocket!

Yeah of course! GTA obviously didn't kill it, that was just a flashy headline

It was fine for 2 years. Which admittedly isn't that long. And after a year and a half the thermal paste went. And it was a shit overclocker. Yeah, no it wasn't the best card...
