Hello everyone, this is my first thread in here. I hope that I'm doing my question properly.
The thing is that my cousin sent me a couple of graphics cards he's used on his computer, he uses them around 6/8hs. a day so they get pretty stressed in a daily basis, that said, I found all the capacitors swollen, excepting the ones for lower voltages which I didn't even care about. I then decided to go ahead and replace the leaked aluminium lead capacitor next to Q2 by a low-ESR electrolytic capacitor of the same specifications. The card worked just fine, but I didn't notice that I set the wrong value, instead of using a 1000uF one, I soldered a 1500uF capacitor, I didn't knew about my mistake cause it worked for around one week until my cousin got it back and failed.
Bad replacement view.
Later on, I wanted to try actually replacing the rest of swollen but still working capacitors by their 1000uF electrolytic match and noticed my error, finally, I replace the 1500uF by the right 1000uF one, sadly, it didn't work either.
Clean front view.
Back view.
I used some of the SMD pads to solder the new capacitors, so that I don't need to stress the PCB so much with heat.
Does anybody know what the cause could be? It's not urgent to fix them but I'd like to get them working so that I can learn more about how this complex hardware works. Thank you in advance!

the gf6/7/8 series are prone to failure with heat and being passive only made it fail faster. he is better off getting another gpu. tell him to get another gpu with a fan. avoid passively cooled gpus. they dont last.
