I had 2 Sapphire Nitro+ RX 470 8GB cards in CrossFire.
I was playing Observation when the game crashed (a regular application crash).
I reloaded the game and tried to get back to that point and I had a hard system shutdown, as if the power was cut.
I thought the PSU (Corsair AX760) was dead, so I replaced it with a brand new one (Corsair CX750M).
My system booted up normally, but the primary GPU was dead. I verified the power connectors were installed correctly, I tried it in both PCIe slots, I tried it without the second GPU installed, and I tried it in another system. The fans don't even spin when the system is powered on.
Dead PSU that killed my GPU, right?
I was playing the game again, with the brand new PSU installed and the second GPU only (with the first one physically removed). About 15 minutes into the game I get another hard system shutdown. This time the system came back up and the GPU lived.
I'm running Windows 7 x64, and if I lose another GPU I'll be dead in the water.
Is anyone else experiencing system crashes with this game?
