I've used this computer for about 2 years without any major issues.

Motherboard: MSI P67A-C43
Memory: G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3
Video Card: Radeon HD 6950 2 GB
CPU: Core i5 2500k

I wanted to upgrade my memory, so I got 2x4GB memory and installed it in tandem with my 2x2GB memory. My computer would start to boot up for a second, then turn off. It would repeat this over and over. I turned it off and unplugged it and removed my old memory, thinking it must have been a problem with the two different sets working together. After removing my old memory, the computer seemed to boot up but had no display.

I then removed the new memory and put my old memory back in. It continued to seem to boot up, but no display.

I took all the memory out and tried to turn it on (hoping to get some kind of error message). Still no display.

I then used 1 stick at a time in each of the 4 slots. I tried one of my old 2GB sticks and one of my new 4GB sticks. Still no display.

Thinking I may have somehow accidentally broke my video card, I swapped my video card for the video card in my dad's old computer. Still no display.

I then looked up methods of resetting cmos for my motherboard, and I tried all 3 - removing the battery for 1 minute, switching the jumper for 5 seconds and switching it back, and pressing the reset cmos button. None of these worked.

I'm quickly running out of options and would appreciate some kind of diagnosis. I think it seems likely that I'll need to purchase a new motherboard, but am hoping that isn't necessary.
 
Solution
Try resetting the CMOS, then install the new sticks in slots 1-3 (you don't mention the model or freq of the sticks so guessing here) if 1600 or better in the BIOS enable XMP and select profile 1 and give it a try

Hi, have you tried to return your old 2x2gb memory card?
then have you tried to use the vga port of your msi mobo?
if you haven't tried this, then i suggest you to return your 2x2 gb memory card then plug your monitor to the vga port of your msi mobo just to check if your mobo is still working.

good luck
