Motherboard will NOT POST! Need Help!!

[kilianjames]

I have just built my first pc, and I bought my parts looking off of affordable builds. Here's my specs:
-Asus M5A78L-M/USB3
-MSI R7 370 4g graphics
-AMD FX-6300 6 core
-2x4 memory
-1tb hdd
-500w POS
I have made sure to plug everything correctly, and when I turn on the power supply I get the solid green light on the mob. When I turn on the power via case button, everything starts up how it should. There's a speaker installed on the mob, but still no beeps or display on the monitor. I'm very desperate at this point, i've gone through countless trouble-shootings. Please help!

If removing the graphics card and starting the board, what beeps getting?

I still don't get any beeps, just the hum of power and a green light.

Now power off, remove all RAMs, start the board and see if any beeps.

 

[kilianjames]

Just removed all ram, leaving just cpu, cooler, fans, and hard drive in the board. I'm not getting anything anymore, no green led or response when I press the power button
-update- the power supply to the mob was a bit loose, things power up again but still no beeps.

Is the power supply ON and both 24 and CPU power cables properly connected?

Yes it was on, I just didn't have the 20 and 4 pin connectors in all the way. Still no beeps without RAM though..

If case speaker properly connected and working, then it's either a board or CPU issue.
Try re-seating the CPU and test again. If still no beeps, then I suggest RMA-ing them.

Hmm i've reseated the CPU like five times now so I doubt it's that. I've seen many similar problems on this exact motherboard, so maybe I'll return it and get another. Thank you for the support

You're welcome.
Just a last check: What are the last 4 digits on a sticker like http://www.guru3d.com/miraserver/images/2011/990fx-sabertooth/IMG_4499.jpg ?

it is 2101

CPU is supported. It could be a board issue, then. Or CPU... Hard to say.

But wouldn't the board start up with intergraded graphics regardless to a cpu issue? I'm just trying to narrow this down so I know which part to return.

 

[alexoiu]

No, Without a CPU, the board can't start/POST.

Update: I returned the motherboard for a replacement and everything is working fine now.

Thank you for the update.
