Hello everyone - new member and first time poster, and I'm in serious need of guidance.  I'm building my third PC, and cannot figure out what is wrong with my current build.  Here are the parts (all ordered from Newegg)

 

 

Mobo:

 

Upon receipt of the items, I assembled according to the instructions, but the system would not POST and no video appeared on the monitor.  The CPU fan, PSU fan, and Video card fan all turned on, but no sounds (I don't think there is an onboard speaker), and there was zero video output via DVI or HDMI.  It was not a black screen of nothingness, rather, the monitor did not recognize a video signal.  The motherboard did not light up with any LEDs or appear to be 'working' other than the fans that did spin.  On startup, the fans would spin fast, but immediately slow down to a low spin and stay there indefinitely.  

Here is what I've done:

RMA'd the PSU - no fix, same problems

RMA'd the Mobo - no fix, same problems

RMA'd the RAM and CPU - waiting to receive both items.

 

Here are a few things I feel I could have done wrong:

Did I short the system somehow?  The case only fits 5 of the 6 mobo holes.  I read this is NOT a problem, but I felt it was worth mentioning.

The Heatsink is HUGE.  Is it so heavy that it is making the CPU not work?

Is the PSU somehow not good enough to power the system?

 

Any and all help would be so much appreciated.  Thank you!

500W is on the low side, actually. I would think a 750W would do you better.

 

For AMD Athlon X4 750K Trinity 3.4GHz:

*100W

 

 

For Radeon 7950:

*500W (or greater) power supply with two 75W 6-pin PCI Express power connectors recommended.
*750W (or greater) power supply with four 75W 6-pin PCI Express power connectors recommended for AMD CrossFire technology.

Thanks netghost. That could be an issue. I will explore returning the PSU for a new one.  Do you have any other comments based on the symptoms?  Could it be that some other part is faulty?

 

Thank you!

That's the simplest and most obvious fix, I think. I also meant to ask if you were getting any beep codes, but if you aren't then I suspect the PSU.

 

Once you do get it to POST I would definitely get into the UEFI or BIOS and check that everything is operating nominally before moving further- as it could also be an incompatibility of the CPU or RAM (which I doubt, but still).

Update:  I've received new RAM and CPU, and used a little mobo speaker to test.
 
Upon installing CPU and heatsink without RAM or Video, I receive three beeps when powering on.
 
When I install one stick of RAM (tried each one, I receive no beeps).  The video card is again, not installed.
 
Does this mean the RAM is bad (again?) Below is the RAM I'm using this time around.  Is the RAM not compatible?  Please help?  I'm at such a loss right now....

You need at least a 750w PSU. Second try installing one stick at a time. Also remove the CMOS battery for a couple of minutes and place it back in to clear everything.

I would go for http://www.newegg.com/Product/Product.aspx?Item=N82E16817139051 and it modular or http://www.newegg.com/Product/Product.aspx?Item=N82E16817139022&Tpk=corsair%20850tx Its a 850w not modular 850 watts to give you a buffer on power.
