I tried two GPUs, the AMD Radeon RX 6400, at first I thought it was because it was PCIe Gen 4. Just tried the Nvidia GeForce GTX 1660 Ti, same issue.
Solutions I have also tried...
-> installing latest drivers
-> reset internal clock
-> update bios
I know it comes down to my bios/motherboard but I'm having trouble finding a solution.

Welcome to our HP User Forum!
Your HP Pavilion Desktop PC TP01-2000a (2Z6C9AV) aka HP Pavilion Desktop TP01-2096, is likely fitted with an Erica6 motherboard with SSID: 8906 (please verify), and a 180-watt power supply with HP p/n: L81008-800 (please verify).
If your desktop is fitted with a 180-watt power supply, that would more than explain the aberrant graphics card/PC behavior, because an RX 6400 requires a minimum 250-watt power supply: https://www.techpowerup.com/gpu-specs/radeon-rx-6400.c3813, and a GTX 1660 Ti requires a minimum 300-watt power supply: https://www.techpowerup.com/gpu-specs/geforce-gtx-1660-ti.c3364.
However, there may -emphasis on "may", be power supply upgrades available for your desktop. According to: https://h30434.www3.hp.com/t5/Desktop-Knowledge-Base/Power-Supply-Cross-Reference-for-specific-model..., it suggests that the following power supplies may be compatible with your motherboard:
310-watt PSU: HP p/n: L64961-800
400-watt PSU: HP p/n: L04618-800
500-watt PSU: HP p/n: L05757-800
Hope this was helpful.

Yes I have the Erica6 motherboard but have already upgraded the PSU to a 400 watt L04618-800. I actually just found a solution which was to unplug the HDMI cable from the GPU and put it directly into the computer. This solution seems to work only for the Nvidia GeForce GTX 1660 Ti though. A question I have is why is it so? I would like to be able to troubleshoot such problems with more knowledge in the future.

When you plug in a graphics card, your PC should automatically disengage/bypass your processor's integrated graphics and route the video signal through your graphics card. From what I understand you are saying, your desktop is not doing that.
Have you checked for the latest drivers here: HP Pavilion Desktop PC TP01-2000a Software and Driver Downloads | HP® Customer Support, and Windows update(s), such as: Install Windows 10 version 2022 with Windows Update Assistant (thewindowsclub.com)?
Then I would access the Command Prompt by typing cmd in your Windows search bar, right-click on the Command Prompt App, then left-click on: Run as administrator, and type in/enter: sfc /scannow -including the space between the c and /.
This may take a little while.
Once completed, copy/paste/enter the following command:
DISM /Online /Cleanup-Image /RestoreHealth
This command may take a little while too to complete. Be patient. Once done, exit out and restart your desktop.
And come to think of it, try downloading/installing the Nvidia GeForce GTX 1660 Ti driver from here: GeForce Game Ready Driver | 419.17 | Windows 10 64-bit | NVIDIA.
