I purchased a Raspberry Pi 4 a few months ago, have had much success with using it up until today. I took the SD card out to update the OS I was using. I reinstalled the Pi to where it was being used, but it would not power on. The Power light is slowly blinking and I have tried multiple adapters, including an official Raspberry Pi power adapter with no luck. I have tested the normal set up to see if the input may have been spiking under load, but it appears to be perfectly fine, it seems like the Pi has just given up. I would appreciate any insight you could provide here.
