I have been building my pc part by part for pretty long time and my first component bought was cpu. I bought it approximately 1 year ago and plugged it into my MoBo yesterday for first time but it seem like it's not working could the problem really be the that I haven't used it for so long ? No pins are bend and the cpu looks pretty fine but pc doesn't seem to get to POST. The CPU I'm using is AMD Athlon X4 870K and MoBo is Gigabyte GA-F2A68HM S1
