Over the last several days I lost the ability to boot from three hard drives. When one went down I plugged in another only to have it follow suit.
The following is the screen I get when I power on the PC.

Obviously there is an issue with the motherboard because one can only give coincidence so much credit.
Each time it's happened was on "power up" after a previously successful "power off". So it wasn't as if the PC crashed beforehand or exhibited any unusual behavior to signify that the next boot up attempt would fail.
Can anyone tell me what the possible problems is and a solution so this system doesn't do the same to the fourth drive I just plugged in?
Thanks.

Well, don't run any more drives on that system,
until you figure it out
*******
I would take the dead drive, to a computer known not to be
killing drives, and test it there.
To protect that computer against damage, I might insert
a PCI IDE card in it, install a driver for the PCI IDE
card, then connect the suspect drive to the PCI IDE card.
If the PCI IDE card is ruined, the motherboard is protected
and only the PCI IDE card needs to be changed out. So that's
a relatively conservative approach, to protecting the
known-good computer. I have several Promise TX2 cards for that.
Once the test computer is booted, you can use TestDisk to
examine the suspect drive as a data drive, and look for data on it.
Maybe it's just the MBR got deleted, and the partitions
are still present.
First, on the known-good test computer, you check at BIOS
level, whether the dead drive can be detected. Enter the BIOS,
look in the disk interface section, and see if the model
number of the drive is listed. That's a basic I/O test,
proving the drive is running internally, and it is able to
send an identity string on demand.
If there is no sign of the drive at all, either an I/O interface
went overvoltage, or +5V/+12V went overvoltage. Something
a bit more physical, low level, and catastrophic.
If the drive is detected, but no sane data can be detected.
perhaps the bad computer has malware which is deleting the MBR
or the partitions.
(I've used this one. It's not a beginner level tool, as the
interface requires interpretation. *Do not* immediately
say yes, to any attempts to write the disk. Press
control-C if you need to exit at any time. This tool can list
files in a partition, for a limited set of file systems.)

I don't know anything about it.)

Those are examples of tools you can try, on your
known-good computer.

If all you owned, was the bad computer, you could:
1) Install a new IDE PCI card. Connect unbroken drive to that.
This covers an I/O voltage problem. It would not
solve potential driver problems though. Or an out-of-spec
ATX supply.
2) Check ATX power supply voltages with a multimeter.
If no multimeter is available, go to the BIOS
hardware monitor ("Health") page, and examine
the measured voltages there. 3.3V, 5V, 12V should
be mentioned, and standards say there is a +/-5% tolerance
on voltage. If you need help with that, post the
voltages you see in the Health page, and I can
quote sections of the formfactors.org docs that cover
those rails.
3) To examine the disk drive controller board for damage,
it helps if the components are facing the outside.
For a few years now, they've rotated the controller board,
such that the components are hidden. On the older
drives, you can look for burned transient suppressors
near the power input point, as proof the power supply
has been "burning" the drives. Now that the controller
boards are upside-down, you have to take the controller
board off to do such a check, which sucks. Because of
this development, it's probably easier now to use your
multimeter, and just check the suspect power supply directly
with the meter. Before, you also had the option of
inspecting for burn marks on the hard drive controller
board.
