I dont know anything about macs. It's the first one I've had but I have a no display issue with my Mac pro I think it's a 4.1. i know the GPU, Ram, and SSD are all good. The SSD has windows 10 so idk if that would be an issue. Could just be bad but I was told it was working which I know doesn't mean much.
 
If you could give the specs of your system someone may be able to help. GPU etc.
 
I dont know all of the specs since I haven't seen it turn on. And the guy I got it off of said it's a 6 core CPU but when I look up the serial number, only 4 core options come up. maybe it could have been upgraded. But it's 16gb of ram and a gt720
 
It's probably a 4,1 upgraded to be a 5,1 and with a 6 core Xeon fitted.

What GPU is fitted and how is the screen connected to it? Can you try the different ports on the GPU?

I don't have a 4,1 so I can only give limited help.

The GPU is a gt720 and it's connected through the HDMI port on it. I don't have a dvi cable or monitor to connect to it with dvi.
 
Do you know what OS is supposed to be installed? Have you tried booting in Safe Mode?
 
Well can you tell us the details of the power on and boot process? Do you hear any chimes? What lights go on (on the motherboard)? Do you have another graphics card you could test? Does the graphics card work in another PC/Mac?

Yeah there is a chime a couple seconds after powering it on. Because of my inexperience, I don't know what it means. The only light that I see come on is the power button. I don't have any other gpus t that I can test since the rest only have dvi connectors. And I've tested the 720 in my main PC and it works fine in that one.
 
Get a cheap AppleOEM GPU like Apple GT120, a NVIDIA 720 - or any other PC GPU non-Mac flashed - won't have any pre-boot configuration support, with the display working only AFTER macOS loads the GPU drivers.

I was just thinking. I'm not trying to load MACos. I'm trying to load windows. Would that still apply?
 
Same apply to all OS.

Without a GPU that supports pre-boot configuration you won't have a display working until the GPU drivers are loaded.

With Windows is even worse because several GPUs do not work with Windows basic/default display driver and take 1/2 hour with Windows Update to get the GPU driver from the internet - sometimes this process does not even work, like when you are not connected to the net via Ethernet.

Well as you just sent that, I got it to work by having the Nvidia drivers already installed on the windows boot drive. Took about 30-45 seconds to display but then it just showed up on the windows screen.

How you are installing Windows?

Macs are not PCs, if you are installing it via USB with a PC, you will damage your MacPro BootROM, making it a brick, with Windows SecureBoot. Just one boot with Windows UEFI installed (installed via USB) is enough to damage the BootROM and brick it over time.

MacPro5,1 have a very specific way to install Windows to AVOID Windows SecureBoot damage/bricking. The only way to avoid it is installing via CSM/BIOS/BootCamp via a DVD install (or boot Windows UEFI installs via OpenCore with ProtectSecureBoot activated).

I'm not installing the windows, I'm just using the drive from my other Windows PC that already has windows and the drivers installed on it.
 
How's that?

Read what I've written already:

I'm not installing it. I just took the SSD out of one PC and put it into this one. No installation at all.
 
If you mean like putting the SSD in the PC then yeah. But I didn't go through the Windows installation media and install it on the SSD while it was in the Mac.

Doesn't matter if you used a PC to install Windows or you installed it directly. The first time a Windows UEFI installed is booted in the Mac Pro, the Mac Pro firmware is damaged.
