I'm facing an issue with my B850-P motherboard where the CPU and DRAM indicator lights are red, and it won't boot into the BIOS. I'm uncertain what the problem could be, and I would genuinely appreciate any help or suggestions.

Okay, here’s a checklist you can follow:
1. Ensure the CPU is seated correctly.
2. Double-check that the RAM sticks are fully in place.
3. Verify all PSU cables connected to the motherboard.
4. If possible, change the RAM configuration—try one stick at a time or swap slots.
5. Inspect the RAM for defects.
6. Do the same with the CPU; look for any bent pins.
7. If you have access to another CPU or RAM, see if they work with your board.
First thing to check is if you've securely plugged in the CPU connector. Sometimes it's easy to overlook. Make sure those cables are tight!
I did connect the two 8-pin cables at the top; everything seems fine there.
It might be worth checking the BIOS version. According to MSI's site, you might need to Q-Flash if you don’t have at least version 7E56v2A2. Did you try that?
I attempted the Q-Flash, but it just rebooted without resolving the issue.
What CPU are you using? It can help narrow down compatibility issues.
I'm using a Ryzen 5 9600X.
I've already done the first six steps, but I don't have spare parts to test further.
