I've just finished building my new PC, but I'm running into a frustrating issue. The system powers on, but it crashes between error codes A2 and 99. I'm using an ROG x670e Hero motherboard, a Ryzen 7 9800x3d CPU, MSI 5070 Vanguard GPU, G.Skill 16GBx2 DDR5-6400 RAM, and a Corsair RM850x power supply. I've already updated the BIOS and reset everything using a USB. I've disassembled and reassembled the build and even tried booting without any USB devices connected. I'm about to reseat my RAM again and see if running just one stick helps. Any tips or insights would be greatly appreciated! If needed, I can share a video of the code cycling.

It sounds like the A2 error might be related to the bootable drives. Have you installed Windows on your SSD? If you moved the SSD and HDD from your old PC, they might require a clean install to work properly with your new motherboard.
That makes sense! I was thinking it might be a compatibility issue. Should I try just using the SSD that had Windows installed on it and leave the others disconnected for now?
