Ok back again with 55 error code endless on and off loop

Question

So a few days ago i decided to clean up the computer. Removed/reinstalled/cleaned video card, 2 fans attached to a tall finned CPU cooler (to clean out the cooler fins) with q-tip and compressed air can, and remove filters and some fans to clean. All done with comp air cans and q tips. Had my anti static wristband attached and on a clean table with tile floors. Had to remove 2 sticks of RAM to get one of the fans.
Also decided to add an ssd while i was at it. All went well except i couldn't get into the bios. Booted to windows fine but hung just after del key press just b4 bios setup. Posted in the Bios section for help and I was told to disconnect all hdd's and optical drive and try again. That worked. Reconnected optical...didnt work. Tried just HDD and it worked. Re connected the optical and it worked. Used the same ports as original (when this all started) and it worked. Weird but good to go. Connected SSD, configured windows to "see" the drive, all is good. Then I disconnected the computer, cleaned up a little of the wiring after the new ssd install (nothing was removed or reconnected) and one fan. Put the covers back on reconnected cables and went to bed.
The next day I go to turn on the computer and i get the dreaded 55 error code and have an endless 3-5 second loop of on and off before it even gets to the splash screen. TV shows nothing. Tried CMOS clear every which way. nothing. Disconnected all components except for 1 ram, and CPU....still nothing. Tried several sticks of ram in each. Nothing works. Tried different PSU's...same thing. Disconnected all USB cables, Mouse, and case switches, same thing. Bench tested mobo with different power supply same problem. Tried different power cords still no worky.
I dont know what to do. The mobo is still under warranty. Idk what I did to make it do this. Static, short while reconnecting audio out to a home amplifier. Static while cleaning up wiring? tried bios a and b, neither work.
Please help...I'm about to just go buy a new board and send this one back and have a spare.     

Answer 1

When I had the original problem, (not getting into the Bios but booted to OS fine) at the end of disconnecting and reconnecting, I had the HDD and Optical and new SSD connected like original and it worked when it didn't before being connected the same way. Just chalked it up to maybe not connecting something completely.
Now I'm starting to think the problems are related
So it worked BEFORE this latest problem. All I did then was add some zip ties to the new SSD cabling and put the panels back on. Didn't check to see if it worked after that, just assumed it did since I didn't do anything of significance.
Then this. I did think about the can of comp air and yes it can do that. I thought I was being careful enough to not let it do that with just short bursts.
I have not tried to remove and re-seat the CPU yet. I will try later and inspect the pins. At this point I think it can be attributed to one of the following things:
1. The EVO Hyper 212 did kind of twist a little (it always has a little when pressure is applied) and bent a socket pin. When I put the panels back on I did have to clean up one of the push/pull fan wires and did twist the EVO a little.
2. Something shorted/is shorting the board to do with the SATA connections. Maybe the SATA plug to board connection.
3. Compressed air shot out some frozen water and corroded some connection somewhere over night.
4. When plugging in the audio OUT from the back of the board to an amp Stereo L & R IN (converts to Surround Sound), the Amp was on and this jolted the board.   
5. The compu-gods have decided to brick my mobo so as to have an excuse to buy a new one.
3 things I have learned. 1. Get a water cooler and not use the big tower coolers. 2. Don't use compressed air especially in swamp-ass Florida. 3. Make sure the crap you plug into the computer is OFF.
