GPU Issues with AMD RX 550

[Tyrannotaur]

Hello everyone! This is my first post here but I haven't been able to figure out how to fix my display and hoped I could get some answers here. 
So I ordered my PC from HP back in December of 2019 as a Christmas gift to myself. I didn't get it until February the following year, but it has worked great until recently when I've been having issues with the display. I will get crashes where the screen freezes for about two seconds and then the display shuts off completely showing no signal. I am forced to reboot the entire PC and it comes back fine. This has been going on for about a month now. 
I have tried to update the drivers multiple times. I have tried AMD's software and doing a factory reset before reinstalling the drivers. I have tried using DDU to remove all traces of graphical drivers and then reinstalling the latest ones from the AMD website. I have tried dusting out the case and reseating the RAM and GPU.  Nothing has seemed to solve the issue.

I eventually had a BIOS beep code error where the PC wouldn't start up and would do 3 low beeps and then 3 high beeps, which I believe does point to a GPU error. When I eventually got the PC to boot again (through magic I assume because I just let it sit for a few days) the PC had disabled the GPU as a "Code 22". I tried re-enabling it only to be met with the same crashes again. 
I assume the GPU is defective or broken. The rest of the PC passes all HP diagnostic tests I've run. Even when the Display does crash, I've had times where the audio from the game or video I was watching still played (though I couldn't control anything). 

My question is what do I do to fix this? I'd like to get a new card to replace it, but the current state of the GPU market is making this difficult. I can't seem to find a place to contact HP directly through email about getting service or a replacement, which I assume is because my warranty is expired.  Does HP offer replacements on GPUs? Is there a card I could buy on Amazon or something that'd be compatible and not break the bank? Any suggestions would be appreciated. 
Thank you for the help in advance.
