not gonna lie this is driving me nuts its 1 AM and my new build refuses to POST.

Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key
No bootable device -- insert boot disk and press any key
Thats all teh monitor shows xD The BOOT LED on the X670 board lights up and stays on. i waited five minutes and nothing changed. My old PC is already sold, so i have nothing else to test parts with. Please tell me this is a cable problem. Ive watched a few build videos to compare and i cant spot anything i did differently :D Im hoping its something obvious that a fresh pair of eyes will catch immediately. im about to throw this thing out the window lol
