Did I ruin my AMD Cpu?

So I hadn't used my computer in a while (1 year+) and wanted to reapply my thermal paste before using it again. I undo the latch on my heatsink and go to pull it up but there is a lot of resistance. So I yank it really hard, and out comes the heatsink with the CPU stuck to it. The lever was still in the lock position. My comp does not work right now (nothing comes up on boot) and I have tested the other parts on an intel rig (PSU, ram, video card) and they all work. So the problem is with the CPU or MB, or both.

None of the pins on the CPU are bent, and it fits back into the MB slot just fine.

Is what I did the type of thing that would definitely ruin the CPU or MB? Man I feel so dumb.

its most likley broken even when no pins are bent i have done this twice with a fx-8350 and and a10-6800k, that when i remove the hearsink the cpu comes with it and in both cases the cpu died but i got them replaced with and rma

If you're sure the CPU didn't suffer any pin damage, I'd bet on the motherboard being borfed.
CPU's are very solid and pins are about your only concern in that case.
The motherboard on the other hand probably flexed too much and something on the printed circuit board gave 🙁

On closer look I'm noticing something in a couple of the socket holes. I can't really tell what it is, it looks a bit like frayed plastic, or something of that nature. The CPU no longer "falls" into the socket, it is held up by the clogged socket holes, however it will go down with some gentle force. One of the CPU pins that corresponded to one of those holes had a little something on the end. I've no idea what, but it came off with some compressed air. The pin still looks fine.

So now my guess is what dudio said, that the motherboard is borfed but the CPU is probably fine.

Any way you can post a decent picture of the socket?

There are three holes in the top that look like there's something in them, I put a red line just outside them.

What you see below the white plastic holes is the locking mechanism. Lift the metal handle/rod just above it. When that handle is upright, the locking mechanism for the CPU is open, and all the holes should be clear. Once the CPU is seated, lock the handle back down to secure the CPU.

Its still there with the locking mechanism up: http://i.imgur.com/u7f5foY.jpg

Ok somehow its working now. I had to use a bit of force to push the CPU into the socket, but its in and I am now getting picture...

Glad to hear.
It's possible you damaged the edge of the locking mechanism and it's really not repairable. If you have it working, don't bump it, and be happy !

Sounds like this is after the fact, but for future reference. A good trick is to fire the system up before removing the heatsink. Run the system about 5 minutes or so to get the cpu hot, then shut down. When you go to pull the cpu undo the heatsink latch, and move the heatsink back and forth in order to break the paste loose. Don't just yank up on it. Kind of twist on the heatsink, and you should usually feel it break loose from the thermal paste, then gently pull it up, clean off the cpu while in socket, then bring up the lever and pull the cpu.
