No post after incorrect installation of megahalems

I wasn't sure where to post this so I think since it's closely related the the heatsink why not.

I feel like a complete idiot for having done this but here goes...

I installed my prolimatech megahalems today but with one problem. I used a backplate that came with a true 120. Not knowing that there was acutally a difference between the one provided and the one I had. Now the difference was that the true backplate had shorter threads. Therefore making the megahalems fit much tighter. Now it sure did seem like a ton of pressure but I (for some reason) went through with it.

As of now, I have the proper backplate on it and it fits correctly, but now I have a huge problem.
The computer won't post, no beeps, no monitor activity, although everything powers up normally. HDDs spin up, fans on, cd drive on.

Comp details.
Phenom II X4 965 CPU
gigabyte MA790FXT-UD5P MOBO
5870 GPU
4gb a-data RAM
corsair 750tx PSU

Try clearing the CMOS. Either remove the battery and wait for a few hours or use a jumper to clear the information manually (check your board's manual). Make sure to remove all power from the board when doing this.

Also, try removing the cooler and reseating the processor. When you cranked down the previous cooler, the act of removing it might have unseated the chip or messed it up in some way.

Hi.

Remove your processor, RAM and GPU, take a look of THIS guide to get an idea about how install your cooler in the proper way. Install the cooler, and after install the RAM and GPU and try to boot again.

I appreciate the help, but none of that info helped in solving the problem.
I know how to install a cooler, I just used the wrong backplate which caused too much mounting pressure.

I think it's pretty much narrowed down the the mobo. I tried the processor in a different computer and it worked fine. I cleared the CMOS with the battery and jumper method. Neither worked.
Everything worked perfectly fine before installing the cooler.

There is a possibility you may have damaged the motherboard by applying too much pressure. Another possibility is you somehow damaged the motherboard during the removal and installation of the cpu heatsink.

The TRUE backplate might of shorted something out on the back of the mobo, or the current backplate is still doing it. Make sure no component pins on the back are touching the backplate.
