Hi, I recently recived a KFA2 780 that I was told crashed under load and produced some coil whine. I tried a couple of new vbioses as well as cleaning the card, and I am currently using this vbios as it has the lowest clocks for a KFA2 780. The card performs fine in Furmark with no issues, with the frame rate about 5-10 FPS lower than usual, but I think that is due to the lower clocks as the FPS has been higher on some other bioses. No coil whine here. When I try to run Apex Legends though, a very GPU intensive game, I can get a few minutes out of it with no problems, but then it will freeze. The coil whine is present here as well. No clue why, the temperatures are fine and the crashes are very sudden. Anyone got any tips on what to do next to improve this card? This is the model, and EX OC edition:

Edit: Just realised that VRAM usage couild be a problem, as this will max out on Apex but not Furmark. Any thoughts on how go about that if it is the issue?
 
My graphics card GTX 780 Ti also stopped working. Everything is fine until you start the driver installation. Then the computer freezes. I don't know what happened to her.

Have you tried the card in a different system? Also coilwhine is normal and doesnt mean that the card is bad/failing etc etc. Lots of parts have coilwhine but carry on working for a very long time.

Test the card in a different machine otherwise the card is pretty much dead. I think its definitely a critical hardware issue. A friends R9 280X did the same thing just recently. Tried switching the bios to lower clocks and it still crashes. I can boot into windows with it, I see it in device manager but it wont accept drivers even with the original bios flashed back on.

Yep, tried it in another and the issues are the same. I ram some memory tests and they came back fine, but when running both Furmark and a VRAM test at the same time there was a black screen after about a minute. Taking a more in-depth look at the PCB I’ve found what I think to be 3 burst capacitors (?) These may be the problem, but I don’t know what these control on the GPU. I will give it a go over with a hairdryer to see if that yields any results.

A hair dryer doesn't get nearly as hot enough to melt solder. It would be worrying if it did

Ah right. Well I have it a go and cleaned up the PCB with some electrical cleaner and I managed to run a memory stress test and Furmark simultaneously for 9mins until the whole system froze. That’s twice the time that I’ve got before so hopefully that shows signs of some progress. Would putting it in the oven be worth a shot as a last resort?

If at this stage you have nothing to lose then bake it. THere is no guarantee that it will fix your problem though but it might though if it gets you another 6 months with it, its better than nothing.

Just be prepared for the worst case scenario which is the card no longer working at all.
 
is that Silver conductive paint in the 1st pic at C140 ?

Not too sure, I'd thinknot but it very well could be. I don't know the history of this card so it could have been used at some point
 
can ya whipe it off easy?

the others could be exchanged easy with a soldering iron
 
I'll see if I can tommorow. If those are the problem, where would I go about getting some? I've given the numbers a google and nothing related has come up.
 
Tear apart old electronics, you can find them on most circuit boards, they're a clone type part so you can just solder on a couple new ones the same size. The issue might be more complex however, whatever burnt c524 might have damaged the opposite side of the board along with it.

Good eye, looks like somebody has been pushing limits.
