My "spare" true original hydro PC I rebuilt that I tried to test in my cabinet today. Sounds like I wants to boot but just keeps looping back and the post beeps come on. I even hear the intial game boot but then just goes back to POST beep codes. Sounds just like my good working hydro PC at first. For reference I put my good PC back in and it boots right up. Video attached. Original mobo was dead replaced that with an exact match, brand new ram and a different but matched processor.
