I recently purchased a ASRock 776Dual-VSTA motherboard. I noticed that this brand of motherboard does not have an integrated graphics card. I have tried several times to boot up connecting my HDMI and VGA inputs through my AGP x8 graphics card but I cannot get anything to display on my monitor. From what I can tell the bios doesn't post and the keyboard doesn't function.

Motherboard link: ASRock > Products > 775Dual-VSTA

Video card link: HIS HD 4670 IceQ Native HDMI 1GB (128bit) DDR3 AGP < HD 4600 Series < Desktop Graphics < Products | HIS Graphic Cards

Any help would be greatly appreciated.

Thank you!
