Ok,

A couple of days ago my early 2009 Mac Pro 4,1>5,1 froze on me while putzing around in Photoshop on a Windows 10 partition. I had to hard reset after the freeze. Upon reset, nothing happened at first. It just hung there on a black screen. Restarted again and successfully booted to select screen and on into Windows again. A short time in, it froze. Reset. Booted into MacOSX Mojave to see what is happening. Frozen again a few minutes in.

Now I get nothing. No POST indication whatsoever...
