Faulty Mainboard?

Hello.
I have just installed (1-7-15) a new FM2A88X Extreme4+ and new A10-7870K CPU to update board and cpu in the "movies" computer.  there are two 2TB movie drives plus a 1tb operating system drive. power supply is an 850 watt and cooling is stock.  I have an R9 270 graphics card so I thought I'd disable the on board graphics and use that.  connected to a 55" television.

Now, the problem is two part. firstly, once running I get an electrical 'static' noise through the speaker system (5.1) and if I turn the volume down to a point where the noise isn't an issue, you can't hear the movie/TV.
but the main problem is the computer keeps rebooting, displaying a line of 'jibberish' then going quiet. not fully shutting down, as the fans are still working but to all intents and purposes, is shut down.  the other thing it does is just freeze.
I've pulled the board, including the CPU and started from scratch, no good. I've removed the external card and switched on the on board graphics, but no good. I've disconnected the two movies hard drives, no good, and I've swapped out the hard drive and reinstalled windows on a new drive. I've done that with three different drives. in fact I've even replaced the drive with another new one and installed Linux. (I'd run out of ideas) and still the problem persists. 
This isn't the first computer I've built and it probably wont be the last. I have a test bed running an ASRock "killer" board and I built a computer for my grandson, also using an ASRock FM2A58M board.  my other computers run ASUS. but this is the first ASRock board I've had trouble with.

I've read a few reviews where the general consensus is the board tends to be somewhat temperamental, but this is ridiculous.

I don't know whether I'm missing something or if the board is faulty.

please, any assistance and guidance would be very much appreciated. 

thanks.

Sorry to hear about your problem. The A10-7870K processor requires UEFI/BIOS version 2.50 according to your board's CPU support list:

You did not mention what BIOS version you are using, or if you updated the BIOS. BIOS version 2.50 was released on 4/30/2015, and given the install date of your A10-7870K CPU, it is unlikely your board has that version unless you updated it yourself. I suggest using the Instant Flash method of updating the UEFI/BIOS, and read the instructions about using it if you've never used it.

Otherwise, the problem does not sound like a peripheral hardware problem, unless your PSU is having problems.

You said you installed Linux, do you normally use Linux on that PC?

Hello Parsec.

thanks for the tips.  I didn't update the BIOS when I installed the board and I apologise for the date thing. I forget that 'northern hemisphere' occupants read the date; mm/dd/year, being in the south, I wrote it dd/mm/year; so the board has literally been in the case, now 3 1/2 days.
I did, however, after reading your comments, go into UEFI and check, it was running  2.5. but to be on the same side, used instant flash to run an update.  damn thing is, at this very moment sitting at 95% and has hung!! so I will shut it down, jump the BIOS and start again.

I will keep posting re; this saga until one of two things happen. a). the problem is solved or b). I switch out to another brand of board.  here's hoping the former wins.

cheers, and thanks.

Oh and I have an old Toshiba laptop that I installed Linux on just to play with, but it isn't on any of my other units.

Hello All.
I apologise for not 'getting back' sooner.
No matter what I did, I couldn't remedy the situation, so I swapped the extreme board out and put in as Killer+  and bother computers are working fine.

with the extreme and the 7870K I tried the BIOS reset, button AND jumpers, even took the battery out. but the problem persisted. Before the board arrived, I downloaded all the latest drivers so installed 2.5 from the outset. But the extreme paired with an A6, the bloody thing works fine and the 7870k in the killer board also works a treat.

I still don't know what the problem was and I am fortunate enough to have a few boxes I can play with.  but more importantly, I'd like to thank everyone for the advice.
