I've got a reference EVGA GTX 780 that I overvolted and overclocked to hell (think I hit ~1450MHz at one point), its broken enough that it won't even cause windows to crash, the entire OS and MOBO just hang. From what I can see, there aren't any blown caps or charring on the back of the card to indicate catastrophic failure, so maybe there's still hope (unless I fried the GPU, lol). Now I know that I have little chance of fixing it, but if I were to start probing around it with an oscilloscope and multi-meter, are there any areas in particular that I should look at first? I know this is kind of vague, but I would be interested to hear from anyone else who has successfully brought a GPU back to life.

Sajin Could try baking it in the oven.
I mean yes, but I'm also kind of interested in playing AVE and trying to figure out exactly what has gone wrong, then baking it in the oven.

Put it in the e-waste recycling bin. It's toast. Or, desolder the core with a hot air rework station, and solder on a new one. (Good luck with that!) are there any areas in particular that I should look at first? Yes, the GPU core itself. Everything prior to the core is quite simple, voltage tolerant, and will typically either work or fail in an obvious way (burn up).

Ahh, that's exactly what I was worried about, but kind of figured was the case. It's the first thing I really overclocked with any significance, so it'll make a nice paperweight momento on my desk.

I'd bake it and hope for the best..Worked for me many times.

According to that very same article, you should most certainly NOT put it in the oven. Something about lead not being good for you.

Yes so, use a toaster oven outside or in a garage near the door. At a local Home Depot could find an oven for $24 or slightly more.

The article also says to not use it in your main oven.

If you're wanting to delve into that level of GPU repair then Buildzoid's AHOC channel might interest you. He mods and frankenstein's and resurrects hardware, albeit usually briefly. He may or may not have some guides for what you're looking for.
Have water, will cool.
