BIOS won't recognize any sata drives after case swap

None of my drives are detected. I moved my system to a new case and in cleaning my power supply i got some moisture in there unbeknownst to me, and broke it. the first time I booted it up everything was connected (including my drives).It didn't work. I did some googling and figured out the power supply may be busted, i replace it, and the system boots, great. But then the BIOS gives me the message "No Boot Device detected" Now here's my suspicion, my guess is when I first booted up the system with the faulty power supply and it didn't work, somehow my drives got fried. So i borrowed a friends drive, connected it, and it booted up and got me into windows. At this point I think, my drives are broken and I get new ones. SO, here's where it gets interesting: The New Drives didn't work either, confused, I tried my friend's drive again and that didn't work. I have no idea whats going on. I have a new power supply, new drives, those should be good. Are somehow the sata ports on my motherboard dead? I don't know. Anything helps. Any assistance would be greatly appreciated.

Gigabyte B75M-D3H
The old drives that I suspect got fried: 850EVO 250GB, and a Seagate 1TB 7200rpm
New drives: PNY CS900, 240GB and a WD blue 1TB 7200rpm
Old powersupply: CS650M
New Powersupply: EVGA 850BQ

  1. When a PSU fails it can (but typically does not) damage everything attached to it. They have protective circuitry to prevent that sort of thing.
    Take your drives and sata cables to your friends house. Test them on a known good working PC. Test both your drives and your cables.

    Then take just 1 disk at a time on your PC on a known good and see if you can detect them with your BIOS. If not, go in to your BIOS and reset it to default settings. If that doesn't work, you might try building a bootable USB disk and flashing the motherboards BIOS (not likely to fix any thing but cheap to try).

  2. Was the AHCI enabled/active when this PSU problem occurred?
