HP Z4 G4 wont post after BIOS Update 3 red 2 white flashes
* Rig: HP Z4 G4 * GPU: AMD Radeon RX 6400 * RAM: DDR4 Non-ECC (pulled from OptiPlex 3050 SFF) Issue: Updated BIOS during prep for CPU upgrade. Post update, PC starts but no POST with 3 Red blinks , 2 White flashes. Fans ramp up after a few minutes, but keyboard gets no power, so I can't do Win + B BIOS recovery. Troubleshooting Done: * Tested each RAM stick individually in slot DIMM1 * Pulled CMOS battery * Let machine run (fans ramp up, light code persists) Main Question: I put the ram in before the update and it worked fine no issues, could the update cause it to not be supported anymore? Anyway to fix this without selling my soul for more ram or it's gone and buy another Motherboard? Any help would do I can't afford a gaming PC so upgrading this is the next best thing.
