HP Elitedesk 705 g4 SFF boot loop after GPU upgrade

[Aesthetiful]

Recently purchased a AMD Radeon RX 6300 to upgrade from the already installed AMD Radeon R7 430 but it when I install the new graphics card into the system and power it up, the system's fans spin for about 5 seconds before restarting and the monitor never gets an signal. I tried:

• Installing the Radeon RX 6300 into a different system (GPU works)
• Updating the BIOS (didn't work)
• Resetting BIOS settings (didn't work)
• Resetting the CMOS battery (didn't work)
• Disabling Secure Boot and Enabling Legacy Boot in BIOS menu (didn't work)

Based on what I could search up before I purchased the Radeon RX 6300, it seemed that the new graphics card would work perfectly fine in my elitedesk. Thanks!

I did some more googling and found out that the Radeon RX 6300 isn't in the list of 'available graphics' for my specific HP Elitedesk model according to my model's datasheet.
