Pc won't boot.

Hello, I have recently bought my components for my first gaming pc, that I built myself. Whenever I boot it up, the fans work the ram led turns on and so does the motherboards led, but I keep getting red debug light for cpu and dram, I have tried swapping the ram and putting them in alone, I also trained them for the first boot, I reseated the cpu but I still could not find out what was wrong. Could it be my motherboard?
