Gigabyte B550 is not starting up properly.
Hi there, I noticed your PC issues after moving and switching from a UPS to regular power. The flashes and loss of sound were concerning. After cleaning everything and restarting, the system would briefly come back but then fail to boot properly. You tried various RAM, GPU, BIOS updates, and even used a USB stick with QFlash, but it still didn’t POST. I’d suggest checking the power supply stability, testing with a known-good motherboard, and ensuring all connections are secure. Also, verify the BIOS version matches your hardware. Let me know if you want help with any specific test steps!
The mainboard includes a QLED indicator to show issues. It also features a second 16x PCIe 4.0 or 3.0 slot for connecting your GPU.
