Failure to boot after CPU upgrade

I recently ordered an AMD FX-8350 to upgrade my Phenom II X4 965 Black Edition. I had not anticipated that I would have any issues, however I was very very wrong.

After removing my heatsink(Hyper EVO 212) and removing my old CPU, I placed in my FX-8350 and applied thermal paste(using the pea method) and replaced my heatsink.

I hooked it up as usual, and it doesn't even POST. Nothing seems to happen at all. I figured it would perhaps be an issue with my BIOS, so I threw in my old CPU so I could update the BIOS, only to find that the same thing happens with my old CPU now as well.

I'm at a loss as to what could be the issue here. I could understand the new CPU potentially not working, but after re-inserting the old one and it still not working, I'm a bit more concerned.

I've already tried removing all but one of my sticks of RAM, as well as resetting my CMOS. I have double/triple checked all power connections, and all are properly secured. I don't know what else could be wrong. Any help or suggestions would be appreciated, as all that happens currently is my 'CPU LED' light is staying bright red. The only other time this happened is when my Hyper 212 fan failed, and I had to replace it which solved it immediately.

Specs below:

ASUS Sabertooth 990FX
AMD Phenom II X4 965 Black Edition 3.4GHz (OC generally between 3.7-4.0GHz)
(Replacement part was as stated above, an AMD FX-8350 Black Edition)
4x4GB Corsair Vengeance 1600MHz DDR3 RAM
Zotac GTX760 AMP! Edition (OC'd to 1150MHz core / 6880MHz Memory)
120GB Samsung 840EVO SSD / 2TB Seagate Barracuda HDD
750W Corsair PSU (Can't recall exact model)
Win7 x64 Home Premium


I'm trying to avoid having to bring this in to the local computer shop if possible, but I may have to. I have built several computers in the past, but I am not particularly knowledgeable beyond basic builds and overclocking. Again, any help would be greatly appreciated!


***EDIT*** I should include the fact that my build unfortunately does not have an in-case speaker. I believe the board I got was supposed to come with one, but it never did. I had never once had an issue in the 2-2.5 years I've had this build however and have not gotten one out of laziness which I am very much regretting now.

No thermal paste got in the socket, the CPU is definitely inserted the right way(AMD Makes it hard to goof up with the very obvious little triangle in a corner), and I have done about 5 builds before, and 3 since my current build. No pins appear to be bent or missing, though I don't have a magnifying glass to get a really good look and I do have poor near sighted vision.

@lfk
I have already reset the CMOS and tried removing 3 of my 4 sticks of RAM. Would removing all of the RAM allow it to boot to POST? Or do I need at least one stick in?

Admirable
you would need at least one stick in. I would just go through a basic what I call did I accidentally bump that check. Just have one stick of ram installed, check all of your cables give them a little push. What also could be the problem is you may still have a charge left in some of the capacitors, with the computer unplugged press and hold the power button for 5sec and then plug the power cord back into your power supply. Then try to reboot
