Hello everyone, today I received a new CPU; it’s the 5700X upgrade from my previous model. After installing it, the system failed to boot, and the CPU indicator light is bright white. It doesn’t even start with the original CPU I had installed. I removed the GPU, but the light still showed up as CPU. After taking out the RAM and reinstalling the GPU, it still lit up on the CPU display. Even when I put the old 5700X back in, it wouldn’t boot and only showed the constant CPU light. I’m unable to update the BIOS, maybe my hard drive is the issue? For reference, my setup includes an MSI B550M PRO VDH WIFI, a 1000W PSU, TUF 3080 v2, the 5700X, and 32GB Corsair Vengeance DDR4 3200MHz. I’m also struggling to get the BIOS flashing, as pressing the flash button lights up red and flashes five times before shutting off. Help is needed, I suspect something might be wrong with my motherboard.

The flashing indicates the BIOS file isn't present. Verify the BIOS is stored on the USB drive, that the drive is formatted with FAT32, the file name matches correctly (often requires renaming), and the USB port is properly connected. Even after these steps, the file might still be missing. Consider reformatting the USB, using a different drive, opting for a smaller capacity device, or switching to a USB2 model which may perform better. Check if your BIOS supports the 5700x3D processor; ensure you're using the most recent stable version. Have you cleared the CMOS memory? After a CPU change, incorrect BIOS settings can prevent booting. Resetting the CMOS restores defaults and should allow the 5700X to start. If none of these solutions work, inspect all connections and cables carefully. Test the components individually on another system until you identify the issue. If the problem persists, the motherboard itself may be faulty. Confirm if it's still covered under warranty—some models last up to five years. Contact customer support for guidance, request an RMA if needed, and reach out to customers if you're outside the warranty period. There are affordable AM4 boards available now, often under $100 if you search for deals.
