it does the exact same thing.
I confess that I'm running out of tricks that don't involve new hardware. If you had a gpu that didn't work properly, you would not be the first. I suggest you go to Newegg and read the (bad, one star) comments for your gpu and see if you find similar symptoms. You can of course also search the net more generally combine terms like "black screen" or "won't boot" with your gpu model. You may land up in a bunch of different fora where people discuss your problem.
I will say though that for the RX 500s I read tons of articles and even though symptoms were often the same solutions were not. Frankly I think my psu started working because I got a new cable.
I was, incidentally, hung up in a situation tonight that had some similarities. I was changing some hardware (swapping one gpu for another) and decided to boot into safe mode to put in latest drivers. I never got that far. So soon as I was in Safe Mode the mouse switched off and I couldn't do anything. If I rebooted I came back into safe mode. After getting very frustrated I remembered I had a mirror of the OS in the closet and by swapping them got the machine to boot.
My thought on this topic is that somehow I did something in the hardware switching that fried one or more drivers. But when the drivers are missing the hardware essentially disappears from the system. But the hardware can also "disappear" from the system if it out and out fails as a unit. But when you put your old SSD in it had all the drivers from its previous service. We have to assume the drivers are there. So it's not lack of drivers.
So now we're looking at hardware and the "big three" are psu, mobo, and gpu.
The ideal thing would be to test by gpu by putting it in another computer. And test the mobo by providing it with a known working gpu from somewhere else.
Brute force trial and elimination.
