Hello!
Upgrading my son's PC and the Mobo is not posting. https://pcpartpicker.com/list/FFmg4d Mobo - B550M Pro 4 Processor - Ryzen 7 3800X RAM - Corsair DDR4 32GB (2x16) 3600Mhz GPU - Geforce GTX 1080 Assembly went fine, all headers and connections are properly seated Troubleshooting steps taken - Tested single RAM stick all slots - Reseated CPU & Checked for bent pins, all good - Reseated PSU Headers - Removed all other header (HD Audio, USB, SATA etc.) - Tested against known good HID Devices - Remove Mobo from case and tested in isolation Continuing to see No POST lights on HID peripherals and Red Lights on DRAM and CPU mobo indicators. According to the Mobo specs, should support the RAM fequency and PRocessor with stock BIOS. No way to flash BIOS without POST? Any leads would be appreciated. Cheers! |

Make sure your 8pin CPU power is connected and is the correct connector. The PCIe
8pin power can often be forced into the CPU 8pin header a little too easily. |

That a negative on the PCI-E Connector. Made sure it is the 8-pin CPU Power and it took no forcing.
I'm thinking its a bad Mobo. Triple checked the compatibility of the CPU: https://www.asrock.com/support/cpu.asp?s=AM4&u=613 RAM is not explicitly on the QVL. Using - CMW32GX4M2Z3600C18 (2x16) QVL - CMK64GX4M2D3600C18 I should at least get to BIOS and get a Memory error if the RAM is not compatible. Still looking for solution here...RMA the board and hunt for something different? |
