After entering OS for about two minutes, it suddenly shut down. Then there was no response when I pressed power-on button.
At first I thought it was because of CPU overheat since I noticed it was approaching 90 degrees C, but that was not the case. It stayed unable to boot until I pulled the GPU from the PCIe slot and every other part started to function properly.
Then I realised there could be something wrong with my GPU. Capacitors could be to blame. But I wasn't really sure, so I took out another board. And history happened again.
And here happened the weirdest thing: I pulled out all the power connectors and started to try one by one. 6-pin was already connected to GPU and when I inserted the 24-pin connector, board booted automatically, but since GPU was not installed so I had no way of knowing whether it booted properly. And with this weird thing, I cut off the power and installed GPU, but it wouldn't boot again.
So I took out my multimeter and found there was breakover of many capacitors and even resistors.
And then I booted the board and measured the input voltage of 6-pin from the power supply, which was so normal at 12.10 V.
Then power supply was not to blame.
And I measured the capacitor beside PCIe slot on the board, and found it was a breakover, too!
So could it be that it was the mainboard that killed my GPUs? (Two GPUs, they died the same way. Well, they are not totally dead, their fans could still spin. And one needs 6-pin and the other doesn't, but it behaves the same when either of them is installed.)
I am now upset and confused. I never saw this kind of thing and I can't do anything for I can't fix it...
Update: Damn. The capacitor of the left DRAM slot is also breakover.
