I know that there are topics on this but this is a little bit of a different situation. My problem is my computer will boot ok, but sometimes every week when i turn it on it dosen't post. However after a few hours it works again. I checked if it was the GPU, it wasn't. I switched the ram on the slots and it posted again and everything was great for a few months. Then this problem happened again.
Specs
CPU Ryzen 3 1200
RAM 8gb ddr4 2400 ballistex
Mobo Gigabyte B450m DS3h
Storage 500gb WD ssd
GPU RX560
Thanks
