[SOLVED] Repeated GPU frying

Not entirely sure this belongs in PSUs but I think it's the PSU

Components
  • 5600x
  • crucial ballistic 3200
  • gtx970
  • sf750
  • sx hynix p31 m.2 ssd
  • gigabyte b550i motherboard
issue:
this is the second time this has happened now. Playing games (mostly destiny 2) and my computer just turns off randomly - no prior issue - and wont turn back on.

When i press the power switch, i get 2 clicks and a tiny PSU fan spin and thats it. this will only happen once per unplug/replug into the wall. subsequent presses get no clicks at all until the computer is un/re plugged again.

As the title suggests, this is the second time that this has happened, frying my second gpu now. (thankfully 970s, nothing terribly expensive yet)

the first GPU lasted about a 8-10 months before the above issue happened (when i bought all the new hardware excluding the 970). replaced the gpu and this one happened just now after 2-4 months

things I have tried:
  • cpu only = cpu fan spins
  • cpu + 1 stick of ram (either slot) = CPU fan spins
  • cpu + other stick of ram (either slot) = CPU fan spins
  • cpu + both sticks of ram = CPU fan spins
  • cpu + m.2 ssd = CPU fan spins
  • cpu + m.2 ssd + both sticks of ram = CPU fan spins
  • cpu + m.2 ssd + both sticks of ram + (presumably fried)GPU in PCie but NOT plugged into PSU = fan spin on both GPU and CPU
  • cpu + m.2 ssd + both sticks of ram + (presumably fried)GPU in PCie AND plugged into PSU =no fans spin
  • cpu + m.2 ssd + both sticks of ram + entirely different gpu = boot up no issues
All of these were the same for both GPU's except for the last one - I don't have a 3rd GPU lying around to try an entirely new GPU this time

Additional things I have done
PSU tester - all voltages appear to be reporting as normal via PSU tester except for PG which is flashing and reading a different value every time (as low as 0 and as high as 950 though most commonly 110 or 100). the instructions for my tester say that this means my psu is faulty. seems like this is probably solved.

can you tell me more about this re-flow process? Never heard of it.
Basically you either take these GPUs to the electronics repair shop and they do it professionally, or you wrap the entire thing in aluminum foil except for the chip and blow at it with a heatgun set to 250°C for a 3-5 minutes. If you don't have a heatgun you can do the same process in the conventional gas oven but it can get tricky and there's a chance of damaging capacitors, so you either wrap it several times or desolder them beforehand.

Keep in mind tho, that this isn't really fixing anything, it just kinda slaps it all back together so it will work for some time and then can fail again.

These GPUs are at least 6 years old, probably bought second hand after who knows how and under what conditions being used for years. A faulty PSU is entirely possible but it's far more likely that your ancient GPUs just decided that this is the day they finally retire.

You can try to 'reflow' either GPUs, it possible that they would be revived for another year or so until another failure. Chips as complex as this don't live forever.

The first 970 was mine the entire time but I totally get what you’re saying and is why I assumed it was a GPU problem the first time.

I got the second 970 for free from a friend.

i totally get what you’re saying though and am trying to upgrade now but I am really trying to avoid scalper prices for a 3080 haha.

What cables are you using with the PSU? Just the stock cables? Stock cables with extensions? Replacement cables? If replacement, what brand?
