Black screen after new ram

[majkis]

So.. one of my computers has Corsair dominiator 4GBx3 1600 Mhz sticks and 4th slot was empty and I got a Samsung 8GB 2Rx8 PC3L12800E stick for free so I figured I might as well pop it in. I seated the ram and I get nothing on the screen when booting so I took it out and tried rebooting and it's still completly black, keyboard mouse "working"(capslock turns on and off and theres light on mouse).

This is my course of action so far;

I take out all the sticks except 1 and issue remains

Try using only the samsung stick

Try a different DDR3 memory i got laying around

Reseat the graphics card

Using HDMI instead of DVI

I remove graphics card and use onboard graphic

I unplug cmos battery for few min and bridge the JBAT1 to reset cmos and I put everything back to orginial state (graphics and 12GB Corsair memory)

Issue remains

 

Motherboard LED;

With hard drive plugged in: A2 and swaps from A2 to 33 and 34 after a while with hard drive plugged in

w/o harddrive its swapping between 53 and 54

 

I'm out of ideas.. help

Something got completely messed up when you installed the new memory stick and the motherboard attempted to train it before booting up. Power down the computer, turn off the power supply and remove all memory sticks. It might not be a bad a idea to remove the CMOS battery while you are at it as well. Leave it like this for 1-2 minutes.  Try to power on the computer with no memory at all and no CMOS batter. Let it sit for a about a minute like until you get an error code to appear. Power down the PC, put in the memory that was originally in there and power it on again. It should work fine.

So I left it on w/o sticks and cmos bat for about 10min, it said E0 on the LED during the whole time from start to finish. After 10 min I turned it off and plugging everything back in and it said A2 for half a minute or so then numbers between roughly 55-40ish(hard to see when its swapping that fast) and then went back down to "steady" 34 and 35.

I do however appreciate the tip Analog since it was something I haven't tried yet, still need of help though

 

Can you actually brick a motherboard using a faulty stick or am I missing something here?

I unplugged the GPU and onboard graphic started to work with all 3 corsair sticks. 

When I plug the GTX780 back in I get video output on the onboard graphics eventhough multi display is disabled, I can enter windows but cant locate the GTX 780 on device manager. 

I swapped to a GTX570, which actually shows display on bootup but once I reach windows logo screen turns black.  

 

I have tried swapping to a different PSU but it made no difference

 

What to do?
