My setup is really bad. The cable mod cables failed first, then the lights started flashing before shutting off. The top red light indicates CPU not detected or failure, while the lower one means a drive not found or failure. I’m not sure if my CPU and RAM are broken. It’s possible the motherboard needs a BIOS update—especially with your MSDI Mag B650 Tomahawk Wi-Fi and 7800X3D.
It could require a BIOS update. Typically, when both the CPU and RAM fail, only the CPU indicator will illuminate since it didn’t reach the memory testing phase, which checks if RAM functions correctly
It's likely your motherboard comes with a BIOS that doesn't recognize the 7800x3D CPU. Updating the BIOS via flashing can resolve this issue. Proceed carefully and consult the guide for instructions. You'll typically need a USB drive formatted as FAT32, containing only the BIOS update file, inserted into the designated port on the back of your computer. Press a button near the port; an LED may light up to show success or failure. Always follow the manual closely.
They're supposed to turn off. Those lights are not for CPU or DRAM fail, it's a rudimentary way of letting you know the POST code range the board is at. It should flash each light as it runs through the relevant POST steps, then turn it off and move to the next. If they do not turn off, then it's letting you know it failed at that POST code, which would probably denote a CPU or RAM issue. Sometimes there is a green one that never turns off, that's okay. To restate: If the lights turn off, all good. It's only bad if they stay on.
