No Post Beep, No Video

[Rick91256]

I went and ate dinner my rig was working fine, when I came back I had no display.

GIGABYTE GA 990FXA Motherboard
AMD FX 6350 Processor
SAMSUNG 840 EVO SSD
GFORCE GT 740 Graphics Card
GSKILL Sniper RAM (2 sticks)
THERMALTAKE SMART650W Power Supply (new)

I Tested Video card in another PC, replaced power supply and tested SSD, Still no display. It powers up and stays running. There is no embedded speaker on the Motherboard. I guess that leaves the processor or MB?
I sent the MOBO in for repair, received it yesterday and reinstalled. I am bread-boxing and still no video.
I installed an internal speaker. No post beeps unless both sticks of RAM are out; then I get continuous short beeps. So far new power supply and MOBO. I tried posting with no peripherals. My computer starts, the PS fans run, the heat sink fan on CPU runs... Is there a way to test the CPU?
I took a stick of RAM from another PC, same results

so when you have all RAM out, you get post beep but with RAM in, no beep at all?

Do you have onboard VGA connector you can try?

You sent in the mobo, but did they do anything to it at all?

If you are able, reseat the CPU. Not sure there's any other way to test it other than to swap processors or test your processor on another PC.

The Ticket said they reset the BIOS. There is no onboard VGA Connector. The unit stays powered on and will
shut down when I used power button.

Did you try another monitor?

 

[Rick91256]

Yes, Tried both ports on the video card too.

If the repair shop reset the bios they probably had a monitor hooked up.
The two things that would of been different between you home and the shop would be the monitor and the cable.
You tried the monitor so give another cable a try.

What I would do:
Unhook everything in the case. Pull all boards except video card. Remove all but 1 ram stick. You can
leave mouse and keyboard hooked up.
If no post beep or video with this barebones config, you have a PSU, mobo or cpu problem.
Get your meter out and test for proper PSU voltages to confirm or eliminate that.
