Hello,yesterday I built a new gaming pc.I couldn't get any sound so I installed drivers and stuff,still nothing.Today I took it to the store from where I bought it to have it checked,and the employee there told me that the warranty may not be valid because of some bent pins (?).Such thing can't be true because the pc would boot and I was able to use it,except that the sound wasn't working!After removing the motherboard,I just took the CPU (i5 4690k) out,nothing more.How can they have been bent?
