So I've had my X470-F for over a year now and it's been working flawlessly, I've kept the bios and drivers up to date, etc.

However, I just went to add a second, internal drive to the computer and now it stubbornly refuses to POST, work, etc. when the 2nd drive is connected.

I've tried setting all the ports to be hot-swappable, moved around which SATA ports the drives are connected to, etc.

But literally the moment the 2nd drive is connected, the bios crashes!

Any tips? Right now the only SATA device is a Samsung SSD (is it possible the SSD isn't 'playing nice')

Thanks in advance!
