Welcome Newcomer. I would seem that you've already figured out the problem. It is not uncommon for one or more DIMM slots to go bad. However, just for the sake of clarity, have you:

1. Used just one RAM module and booted?
2. Used the same module to occupy all slots, and booted?
3. Tried all of your RAM modules one at a time?
4. Using each stick in every slot, one at a time, of course?
5. Tested your RAM with MemTest86+?
Edit:
6. Checked the ASRock website for your mobo and RAM compatability?
7. Consulted an ASRock tech to confirm your mobo supports your RAM?

Ok, so your display comes up as long as you use only one of your DC kit sticks. I just want to be clear, you've tried all of the following configurations:

1. | _ _ _ = successful boot
2. _ | _ _ = "
3. _ _ | _ = "
4. _ _ _ | = "

Repeat with second RAM stick

1. | | _ _ = no display
2. | _ | _ = "
3. | _ _ | = "
4. _ | | _ = "
5. _ _ | | = "
6. _ | _ | = "

where "|" = occupied DIMM slot and "_" = unoccupied DIMM slot

If the above is true, then the you likely have a bad mobo. You can try to update the BIOS, but if the proves unsuccessful, I would consider contacting the manufacturer regarding warranty (assuming warranty is still good). Otherwise, you'll have to get a new mobo.
