I've tried googling everywhere to see if someone else has had this issue, there is no search result anywhere after this much troubleshooting, especially with a mac pro.
No matter what I do I get the question mark folder with no chime when trying to boot up.
This all happened when trying to install high sierra from a working hard drive onto a new nvme pcie card and during 95% completion it restarted and was forever stuck like this.
I tried the nvram reset, computer ignores command+option+p+r command, same result. I tested this keyboard on an imac and it works perfectly. I tried every USB port, same result
I tried 3 different hard drives with boot volumes, nothing recognized. I even bought a new hard drive from a trusted ebay seller that sells Mac OS freshly installed hard drives from a Mac Pro 5,1 and still nothing. I tried every single sata port as well, even the 2 dvd drive locations. I tried each hard drive separately with no other drive installed (including the nvme to pcie card).
I tried USB sticks with the snow leopard dvd and even windows, nothing.
I tried the original cpu tray, original 5770 gpu, and different types of working ram, same result.
I tried the holding the power button when booting up until it beeps and light flashes, same result.
I even found my original recovery dvd with 0 scratches and put in my original dvd drive and still the same result regardless of keyboard combinations.
