Computer produces beep code, then boots to Windows.

[DefconX5]

Hello, I'm a computer technician myself. I'm coming across this issue with the HP Pavilion AIO 23-Q127C Desktop for the first time and it seems to have driven me a little crazy. I'm the type of tech that just refuses to give up. So when I first power on the computer, it produces a beep code. The beep code is (3 long beeps and 4 short beeps). It does this 5 times and eventually boots up to Windows. Everything works completely fine after that. According to HP's knowledge base and TWO HP Support Reps, this indicates "The system board displays a power failure (crowbar).*" First rep stated that the motherboard was in imminent failure and recommended replacing. The second rep stated that it means various components are defective, but most commonly the RAM. I've replaced motherboard TWICE, processor, and ram, but still have the same problem. There's not much to replace after that except for the display and I doubt that is the cause of the issue. There was one thing I've tried and that's the converter board just so that I can rule that out. No change. I found one article that experienced the SAME EXACT symptoms. I read through that article and performed those EXACT troubleshooting steps which was verifying that the power adapter was connected very securely and also reconnecting keyboard/mouse usb (not sure what that was about, but supposedly resolve other peoples issues). I'm at a complete loss and super confused. Hopefully someone can help. Thank you.
