Hardware help: monitor suddenly stopped getting a signal from PC

For an external graphics card? I'm not sure why you would think that the motherboard would know that a peripheral card had died.

Because testing the graphics card has been a part of PC POST since the days when the interrupt and DMA controllers came on separate chips? It usually does this before testing the keyboard, so that it can give you the classic "press F1 to continue" message.

Well well you live and learn. Ta.
