Issue occurring with PC startup, likely related to BIOS update problem.
You're starting a PC build from scratch and running into POST problems. After installing components, it briefly powers on with a bright red signal but then shuts off repeatedly. You've tried a BIOS flash before and haven't confirmed success, but the CPU power-off method seems to help. It's unclear if the BIOS issue is the root cause. Before proceeding, ensure you have a backup of any data and consider testing with minimal components first.
The CPU power connector should be connected to the bottom of the heatsink above it.
