System powered off and now won't POST

So I left my PC, came back a few minutes later and it was off. So I turned it back on, and straight away turned off again and back on in a loop, trying to turn on but turning off straight away, turning just for enough time for my fan LEDs to turn on and my HDD to click. I then tried to see if it was plugged into the wall socket properly, I then turned it back on and it seemed to boot up, although I suspect that was because I had left it off for a few seconds. However it did not post, everything gets powered up but there is a red CPU LED and 00 was shown on the two LED segments.

I will list the component below, but I have a P9X79 Pro with a 3930k, that I have not yet overclocked with a AX860, that is a replacement for my AX850 that died two years ago on the same system. Things to note are that the system was a bit dusty but the CPU fan wasn't on full load, that the system was idle when it powered off and that I was loading it with CS:GO just minutes before.

I then later noticed above the LED segments in the bottom left hand corner some black matter that shouldn't be there. It was stuck to the motherboard, sort of looked like something had melted, so I pushed it with a piece of cardboard and it came off. I have no idea what it is, but it might have done damage to the motherboard. I have no idea what it is or where it came from, logically it can only either be part of a spider or something that got into the system(although I think that is unlikely) or from the system itself.

P9X79 Pro with the latest BIOS but with a older Intel RAID module
3930k with a Silver Arrow SB-E Extreme not overclocked
16GB of DDR3 2133, Blue Ripjaws I think

That does not look good, I've got two things for you to try
First, Get some Rubbing Alcohol and try to clean that off best you can. Only use rubbing alcohol because it'll evaporate rapidly.
Second, Remove the CMOS battery for a while or connect the jumpers to clear the CMOS and boot the system, then revert the jumper back to its original position. If that doesn't work then your motherboard is likely dead. That sucks too, x79 mobos are expensive as hell.

I don't really have anything to clean it with, and there seems to be metal on the melted plastic, and maybe a pin on one of the chips missing. I pressed the cmos button but it didn't solve the problem, it did however cause the system to try and turn on.
