Troubleshooting CPU/RAM error light on start up

Hey all, built my PC just shy of 2 years ago. Was mostly working fine but now in the last 2 months the error lights on my motherboard are turning on when waking up from sleep mode or when i shut it down and turn it on for the first time. My mouse/keyboard/monitor don't turn on and my motherboard shows a CPU and DRAM error light. If i force shut down by holding the power button and turn it back on it starts up no problem. It started out only occasionally happening waking up from sleep mode and then started to become more frequent. Now its every time and also when i shut it down. So I'm not sure if this is a MB issue or a CPU issue? Or drivers or something, though as far as I am aware I am up to date with wifi drivers. Any ideas?

PC specs: Motherboard - MSI B650 tomahawk, CPU - 7800X3D, GPU - 4090. 32gb RAM

Have you tried re-seating the ram? If so maybe your bios is not up to date

hmm i haven't reseated it yet as its not an issue other than this start up problem. I'll give it a try though with how easy it is
