Question PC only boots after clearing CMOS – won't power on otherwise

Hey everyone,
I'm having a strange issue with my desktop PC. Every time I shut it down completely, it won’t turn back on unless I clear the CMOS using the jumper. When I press the power button without clearing the BIOS, nothing happens—no fans, no lights, completely dead.
Once I clear the CMOS and try powering it on again, everything works perfectly. It POSTs, boots into Windows just fine, and I can do everything—gaming, editing, heavy workloads—without any issues at all. It's stable while running. But if I shut it down, the whole process repeats: I need to clear the CMOS again to get it to boot.
Things I've tried:
  • Replacing the CMOS battery
  • Checking all power cables and connections
  • Resetting BIOS settings to default
  • Updating BIOS to the latest version
Specs:
  • CPU: Ryzen 7 7800X3D
  • GPU: GIGABYTE GeForce RTX 5070 AERO OC 12G
  • MOBO: GIGABYTE B850M AORUS Elite WIFI6E ICE
  • RAM: KLEVV CRAS V DDR5 32GB 6400MHz CL32
  • PSU: ROG Loki SFX-L 850W Platinum White Edition
  • SSD: PNY CS2150 1TB Gen5 PCIe NVMe M.2
Any ideas on what could be causing this? Is my motherboard dying? I'd really appreciate any help or suggestions.
Thanks in advance!

For the sake of relevance, please state the BIOS version for your motherboard at this moment of time.

If you're having to introduce your hands into the system before it shows signs of life, that would indicate that you have a grounding issue. Do you feel a mild tingling sensation when you touch the metal part of your chassis while your bare feet are making contact with a tiled(non wooden, non carpeted) floor?
