Hi! Just got a new case and reinstalled all my components. Everything was working great before reinstalling. Now, my hardrives will not show in BIOS or in Windows. I have changed cables, ports, power supply parts, and everything, but they will not show up or spin. I have tested same cabling with SSD and it will work, however the HDDs will not spin or show up 2 of them are about a year old, and one is brand new. How do I go about fixing this??

Thank you in advance as I'm loosing my sanity here
