Check the QVL list to see what BIOS revision is required for that board to support the FX-8120. If you've got something earlier, you might be able to take it to a local computer shop to get it flashed for a small fee (unless you want to buy a cheap AM3 CPU to do it yourself).

It is very possible that you will have to update the BIOS before using that CPU.

Do you get any lights on the MB when you power it on?

I think your power supply is underpowered for your build. DO you have access to a 700 watt PSU? That is what I would check first.

Otherwise by my experience the symptoms you describe indicate a possible DOA mother board. Seen it many times, if the fans and/or LED's are running but no post activity than that is typically a MOBO issue. You should get a stronger PSU regardless.

Consider that your CPU uses 125 watts of your 500 by itself, than the video card will suck down quite a bit, other peripherals etc.

It's not the bios version, because according to the list, this cpu is supported by all versions:

Try to boot with only one memory stick and disconnected disks and reset the cmos with the jumper. Maybe that helps.

Your PSU, while not the highest quality out there, should easily power your rig. The HD7750 uses only around 56W running flat-out. I'd be surprised if your rig pulls 300W from the wall.
Check the QVL list first, then go from there.

Thank you for all responses...Will a computer repair shop be able to determine if motherboard is DOA? Will they be able to re-flash BIOS?

They should be able to. You can also call ASRock and they may be able to cross ship a replacement without you having to spend money at a repair shop.
