So I recently picked up an old MP 3,1 from workj that was having some hard drive issues. I replaced the hard drives and then upgraded the OS to Catalina, The next things I did was to switch to an SSD on a PCIE platter, I then tried using a MSI RX570 GPU.

Then I started running into problems, the Mac would power up and it would work for a time, but the screen would go black and then the fans would start going to full blast, not 100% sure which fans they are but I think they're the PSU fans. I'm not married to the boot screen etc but having something stable would be nice and at this point I'm lucky if I get 10 min before it shuts down.

Any assistance or clarification please let me know. I'm close to not even trying any more with this guy, which is a bummer- I kinda like it when it works.

Thanks!
