Computer refuses to POST; CPU Error LED is lit up

My PC has been refusing to post for the past few hours. It'd been working fine for months and even earlier today. It just randomly shut itself off while I was making food. While it's refusing to post, the CPU Error LED is lit up. I've tried swapping my CPU fans with case fans to see if the CPU fans were going bad (even though my cooler is only 6 months old). I know that there's a setting that doesn't let the PC boot if the detected CPU fan speed is below a certain RPM, but I can't even get to the BIOS to turn that setting off if that is the issue...

To be clear, everything turns on when the power button is pushed. All the case fans work, both CPU fans work, the graphics card fans work. The only thing that's different is that the CPU Error LED is now on and my computer can't even get to the BIOS. Also, clearing the CMOS won't do anything, as the CMOS battery holder was broken when I bought the motherboard, so pretty much the CMOS gets cleared every time I cut power to the computer.

I tested the power supply and it works fine. I'm thinking the board just died somehow. Judging from other people who had the same issue as me, their board had died and their CPU was fine.
