I just finished my first build. Upon trying to start it for the first time, everything RGB was lit up and all of the fans were spinning. The monitor however, was completely black, and my keyboard and mouse plugged in via USB weren't doing anything. Upon closer inspection, an orange light with "DRAM" written next to it was lit up. So far, I've tried re-seating all of the RAM, and removing the CMOS battery for about an hour and then trying again. This is really frustrating. Especially because I can't get into the BIOS to perform anything there.
