The hard drive has either failed or is failing and needs to be replaced.

These codes indicate a Hard Drive failure. This is extremely common with Optiplex 780 systems after aging.
It's best to replace the drive with one that was manufactured more recently. You can also buy a SATA SSD and a 3.5" adapter to fit in your systems.
