I appear to have bricked two 657094-001 motherboards in two Compaq Elite 8300 SFF.
On both occasions I noticed the sata controller in the bios was set to IDE. I changed to AHCI and as expected Win 10 blue screened. Not a problem I will just switch back to IDE in the bios and take it from there.
This action bricked both motherboards. Bios does not post, Fan's run and get progressively louder. Sometimes the bios appears - perhaps one out of 40 boots and I have jumped into the bios and flashed but still no boot after a restart. Also tried numerous cmos reset / battery pulls.
I'm at a total loss. I have never bricked two motherboards by switching from IDE to AHCI and this is now getting expensive.
Any help ?

I would also not have expected this problem, as I have myself changed from IDE to AHCI without this kind of result.

The HP Elite 8300's are out of warranty.
After seeing this happen twice ( I've only done it twice ) I'm sure it would again if I repeated the same steps. I have other 8300's here and it's almost tempting to video the motherboard being bricked by the switch to AHCI and boot.
I just don't understand it. I have been fixing computers for 15 years, IDE to AHCI switches are fairly common jobs which I have done many times.
I'm wondering what would happen if I connected a drive with an IDE mode installed OS to one of these Elite's which was already in AHCI with secure boot on.
