Just upgraded my PC to Ryzen 7950x today. I only swap out the motherboard, ram and cpu, rest of the parts were all kept from my old one.
When I turned on the machine, the power is on, the fans are on, but there are no display, no mouse and keyboard. The keyboard light doesn't even flash on start up. I have no idea what's going on.
For troubleshooting, I disconnected all drives, ram and GPU from the motherboard, still nothing. I tried swapping out the CMOS battery and reseated my CPU and nothing.

For the last couple of months, my computer has been shutting down by itself randomly while in sleep mode, is it a sign of PSU failing? Could that be the cause on my new build?
