I recently bought, 8gb of ddr4 memory, a Ryzen 5 2600, and a MSI b450m pro-vdh motherboard. Whenever I have everything plugged in properly, I've checked multiple times so did my roommate, my motherboard lights up lights that indicate the CPU and the ram is not detected. I went as far as buying a new PSU and a new processor thinking that was the issue yet the issue still is there. Any help would be much appreciated as I need my computer working for school.
