I recently put together a new PC, but I'm seeing a red light on my motherboard labeled 'CPU'. I've already attempted to reset the CMOS and flash the BIOS. Can anyone suggest what I should do next? Just so you know, I'm using a Ryzen 9 9800X3D with an MSI MAG X670E Tomahawk WiFi motherboard.

Make sure you're connecting the CPU power correctly. If your motherboard accepts multiple power cables, try plugging in both the 4-pin and 8-pin connectors if you haven’t already.
I've checked that, and all the power supply cables are definitely plugged in.
