I recently built a system for my girlfriend and had to finally RMA the mobo for the exact same issue. The mobo tested fine but the Northbridge heat sink springs were loose and the mobo wouldn't post for the heat warning. Please look closely at the NB and SB heat sinks and tighten them just snug and re-test.
Beep codes are CPU generated, if you don't get any at all and presuming there is a speaker connected, then the fault is the CPU. It could be seated wrongly, it could be that your PSU isn't up to it. Might just be the CPU and \or Mobo are US.
As far as I know it has an internal speaker, as I've always heard a beep whether there is a monitor connected or not.. I can't tell whether it's booting, despite the HDD's running and everything sounding like it's making a move.. no signal through VGA or HDMI and no beepThere is a 4 pin connector for a speaker, but I've never had one plugged in
Heatsink seems fine, recently purchased an Arctic Cooling Freezer 7 Pro and it fits nice and snug.
I'm starting to lean towards it being the PSU, as it's the only component left that is isn't pretty much brand new. If I buy a new PSU and that doesn't fix the problem I'll be taking the mobo back to the store and have them test the system out.
By going at the symptoms you stated, it does look like a failing PSU.As far as I know it has an internal speaker, as I've always heard a beep whether there is a monitor connected or not..

Any PSU's that come recommended.. I'm looking at an EZ Cool 650W Active PFC PSU, 12cm Fan, SLI Ready
Ironically I'm currently running an Ez Cool 600W and it hasn't bugged out.. untill possibly now, must be 5 years old at least
MrRevolutionary,
The CPU heat sink and cooler isn't going to be the issue as your not posting to it yet. But do please see if you can wiggle the Northbridge or Southbridge heat sinks. The NB heat sink if loose will not let the system post to the CPU till it's in good contact. Likely you checked this but just want to make sure you weren't thinking I was discussing your CPU cooler.
