I'll be using this Mac Pro and the screen will go black and the fans will rev up to maximum RPM. I have dual CPU and 32 gigs of RAM, stock Nvidia GPU. I will run AHT, extended test mode, it will never repeat what happens when the screen goes black and fans rev up. I've tried swapping RAM sticks and even tried swapping the GPU, still happens occasion. I suppose it could be power, but then if it was power, wouldn't the issue occur while running diagnostics. I'm at a loss and looking for advice.

Thanks :)
