Which AD/DA card ?
Did you plug that into the PCI slot before you started up the computer again ?
If yes, remove the AC power to the computer, remove the AD/DA card, then try booting the computer - you will probably have video.
You DO NOT need to change the Initiate Graphic Adapter setting in the bios Setup unless you have a PCI-E video card installed in the PCI-E slot, and even then, with your mboard's main chipset, changing that setting in the bios almost always has NO EFFECT regarding whether you get video while booting the computer or in Windows itself (unless you're using Windiows ME or previous).
However, a problem caused by installing the AD/DA card COULD cause no video.
Shuttle XPC SG41J4 (home support page)
Supports dual-slot graphics cards
The Shuttle XPC Barebone SG41J4 supports dual-slot (double-width) PCI Express graphics cards without additional power connectors. Please note, that the integrated graphics will be disabled, while using a discrete graphics card.
"Please note, that the integrated graphics will be disabled, while using a discrete graphics card."
NOTE - that ONLY applies to PCI-E video cards, NOT PCI video cards
FORM FACTOR - Shuttle Form Factor / Support mini-ITX also
CHIPSET - Intel G41 + ICH7
(1) DVI-D port
(1) VGA port
(1) PCI-E x16 slot
(1) PCI slot
POWER - 250W
Support List tab - Graphic Card Support List
Lists ONLY PCI-E cards
"Caution: Due to some of high-end graphics cards require higher power consumption, please refer our 'Power Supply Calculator' to check what kind of power supply need to upgrade. "
I know from experience with another XPC system that SOME of the cards listed are NOT supported unless you replace the power supply with an optional one, or a clone generic power supply, that has more wattage capacity.
If your AD/DA card requires that the system has a power supply with a capacity of greater than 250 watts, your system may NOT boot.
The PCI slot closest to the center of the mboard if you have more than one (in this case you have only one) usually shares it's IRQ with the video adapter, whether you're using the onboard video, or a video card installed in the PCI-E sot. If you install a PCI card that is not a PCI video card in that slot, you're likely to have problems.
Apparently some PCI AD/DA cards can be forced to try to use a different IRQ.....
......but that may not work when your card is installed in that PCI slot.
If you ALSO have a PCI-E video card installed in the PCI-E slot, your power supply may NOT have enough capacity to support both the power requirements of the PCI-E card's video chipset and the PCI AD/DA card, in which case the computer will probably NOT boot when both are installed.
