Mac Pro 5,1 goes to black screen & loses video signal upon successful boot and disk selection

Post Body

I'm currently facing an issue with my Mac Pro 5,1 where the system will boot with a chime normally and present the OpenCore disk selector successfully. I choose the main home disk then Apple logo and loading indicator show up & complete then the screen goes to black and I lose video signal.

I tried resetting PRAM & NVRAM but that didn't really do much. I'm using an NVDIA Quadro K5000 GPU and have tried different video out connectors like DVI and displayport but that doesn't seem to help either.

I tried booting into recover disk but it didn't load all together. I also tried booting in verbose mode and I saw all the log messages seemingly logging successfully but it was being executed way too fast for me to determine whether there was an underlying issue or not.

Lastly, to give some historical context on how this started. I upgraded my Mac Pro to Monterey I believe and abandoned the system for several years and now I'm trying to boot it up and get it running but I'm stuck with the issue mentioned above.

I'm wondering how to go about continuing the troubleshooting steps. I'm a bit lost in the process and would appreciate some pointers because I feel like I'm close to finding a solution, it's just a matter of properly diagnosing and triaging root cause of the problem.
