When I built my PC, I learned about this beforehand, so when I heard the "crunch" I wasn't worried. Until the thing wouldn't boot.
I took the CPU out, and sure enough, I'd bent a few of the pins in one corner. Fuck. I then spent the next couple of hours with a tiny magnifying glass and tweezers, painstakingly trying to bend the pins to where it would boot again. 20 min of bending, stick the CPU back in, try to boot... nothing. Several times.
Finally it booted, miraculously. I'm never taking that CPU out again.
