This is my second build and I'm at a loss as to what steps I should take.

Here's the problem:

I installed all the components and had initial problems with the motherboard not accepting two ram sticks. I removed one and everything worked fine. I attempted to try and see if my new ram sticks were faulty by using two others, the same problem occurred; with two I wasn't able to get to the bios.

After switching back to one of the new ram sticks I am unable to even get the pC to turn on. I have a green light for the power on the mobo but that's it.

I've tested the PSU, the GPU and the RAM. I've also tried to run with only the CPU and sound/power connectors but the same problem arises.

I'm thinking I might have damaged my motherboard somehow when switching out the ram but i'm not sure. Is there anything else I could try to identify the problem?

Thanks for any help.

Update:
Prodigy bitfenix
Asus P8H77-I
Corsair Vengeance 2 x 4GB 1600mhz
Intel I5 3470 s1155
ATI Radeon 5770
Corsair CX500M

Have a look at how the memory sticks need to be placed in the board.
Some boards can be fussy on where the memory has to be placed in the dimm slots provided.

Depending on the memory mode used, Single ch, dual ch, or triple ch modes.
Often it can cause a fail of the board booting.

If it worked with one stick of memory, then it is down to where it should be placed when fitting two sticks, and the given slot placements in the board.

Don`t forget if you used different memory at some point and then tried the new stuff again, and it did not work.

The bios of the board may need a reset as it will retain the details of the last memory placed in the board and store them in the bios.

If the speed and timing values differ from memory...

The bios of the board may need a reset as it will retain the details of the last memory placed in the board and store them in the bios.

If the speed and timing values differ from memory modules, it is often the cause of a fail to boot, if the bios is not reset. As it will be trying to work memory on the last values stored.

For example 1333mhz memory with 10-10-10-16 timings.
Take it out place some other stick in in the system of 1066Mhz 7-7-7-12 timings.
No dice?

Reset the bios. Let the board re auto detect.

I've reseted, went from scratch and checked all my connections, and still nothing when I attempt to boot (literally no fans turning on or any noise whatsoever).
