|Well I don't know about the Dell OptiPlex 780, but the BIOS chip in the Dell OptiPlex GX150 is soldered directly to the board. And the in-circuit programming I was referring to is programming you would do using an adapter to connect say a PC serial port or USB port to a programming port directly on a PCB. The programming port would most likely be wired directly to the BIOS chip, power to the motherboard applied normally, possibly with, possibly without the CPU present, the programming adapter would halt the system from booting, and allow programming to take place.|
At any rate, taking it to a tech, is probably your best option at this point.
