If no none has heard of your motherboard, and you typed it in correctly, it likely came in a prebuilt PC. As has been stated, If you have a PCI express slot (any, not just 2.0/2.1), then it is compatible with the board. You should then focus your concern on if your power supply can power the card. Will this be replacing another video card, or IGP? Power supply brand, wattage, and +12V rail amps would be helpful as well. This should be on a sticker on the psu, it should list 3.3, 5, 12, etc. We need the +12 number.
However, it will not tell you which version of PCI-e the motherboard has; v1.0, v2.0 or v2.1. If it has a PCI-e port. If you do have a PCI-e port then you can install the HD 5670. However, be cafe and buy a HD 5670 that is PCI-e 2.0, not PCI-e 2.1 bacause PCI-e 2.1 has compatibility issues with the older PCI-e 1.0 slot.
