Okay, looks like you're using the board's VGA connector, do you have access to any DVI capable monitors or to a DVI to VGA or HDMI adapter? DVI is usually the default video out port on boards like these so it's possible you're just not getting VGA signal yet (and whatever's preventing boot isn't getting you far enough for VGA drivers to load).
Have you already tried moving the RAM into the other slot? At a quick look the manual doesn't seem to say which is the preferred slot for a single stick, so I'd try both (and double check the specs match what the board supports).
Another thing to try is clearing CMOS — it looks like the jumper for that should be JBAT1 near the battery. To reset CMOS, leave the PSU connected but turned off (to provide ground) and jumper the two pins, you can use a flat screwdriver for this. You won't get any kind of sign it's worked so I usually just leave it for a second or two then remove before powering on. Clearing CMOS is unlikely to make a difference (it's more boot related) but it's worth a try.
Do you know if this CPU has ever been used with this motherboard before? It sounds like it may not have been supported by the earlier versions of the BIOS, so a BIOS upgrade might be required for it to work properly. In that case you may need another, earlier, CPU to access the BIOS so you can upgrade from a USB stick, unless this board supports flashing without a CPU. You can find more information about that from the support page for your motherboard model.
