I’m new to building computers and this is my first. Ive just purchased everything fairly recently (within a month) and I’ve installed everything correctly according to my manual and I’m getting all power to everything (CPU, GPU, Computer fans, etc.) but my DRAM debug light on my mobo is lighting up and if I take out one stick of ram to begin the typical diagnostic test instead of my DRAM light it’s the CPU light. I’ve been told to flash the bios through customer support but this mobo should have came installed with the latest and up to date version. Any suggestions or tips would be great!
