So I was moving today and I was walking down the stairs and slipped with my CPU in hand, It doesn't seen to have any damage on the box. But I'm still very worried I might have broke it as this is my first pc build
Well your CPU is very small, maybe just 1.5x1.5 and doesn't have pins on it, so it should be ok. Just make sure it is not dirty when you install it into your PC.
Ummm... well what do you want us to say? If it was still in it's box it's probably fine... All you can do is build your PC and if it doesn't work then you may have done some damage, but until you try it there is nothing that can really be said.
