I'm building my computer for the first time and have it on a workbench to check that everything is ok.

I hooked up my CPU, RAM, GPU and PSU (of course) along with just a keyboard with USB.

The fans spin up and the LEDs flash around the board but then it stops and stays red on BOOT_DEVICE_LED with a q-code of 99.

I'm not sure what to do at this point...anyone have any suggestions? Let me know if I need to post more info.


Thanks!
