I think my old Motherboard is killing my hard drives.

Title related. 
Here's the whole story: 

     I wanted to give my brother an upgrade from his old Pentium build, and I had an old HP machine with an AMD A8 7600 lying around. He hands me his PC, and I swap the Motherboards. The CPU and Coolers stay on them, but the RAM, Drives and PSU stay the same between the builds. I boot it up, and...

     "No boot device."
Alright. Maybe it just doesn't like his drive? 

I plugged in my personal windows boot drive, as it's the only one I have at the moment. I boot it up on this drive, and...

     "No boot device."

Strange. Eh, he can deal with his Pentium while I figure this out. I put the builds back together, including my personal one. I give him his PC back. I turn mine on, and...
     "No boot device. Try unplugging any drives without a Windows boot on them."

Ok, this is kind of normal. Doing this helped last time, and... 

My personal build, which booted fine before I plugged it into the motherboard from the only HP PC in the house, was now not recognized as a boot device. My brother's PC was having the same issue.

TL;DR: After swapping parts from several builds, several of my drives no longer boot windows after being plugged into a motherboard from an HP PC.

I have a theory that something on that motherboard is killing any drive it doesn't recognize. If that is the case, this is genuine cause for legal action against HP.

Hi

Based on the concept of a GPT/MBR possibility across the PC's, I would check and Double check the BIOS settings for compatibility, and even hostility.

I would make a DVD/USB with Lubuntu on it as a yard stick and start from there.
