Hello, I recently installed a Asus Z97-A motherboard with an Intel 4770K processor and replaced my RAM as well. Hardware and software installation went very smooth. However, since this installation while playing games I now get a crackling and popping noise from my speakers. I have no performance issues in regard to frame rate or CPU efficiency. I am running the audio out of an Nvidia 770 card. I have updated my motherboards BIOS, reinstalled the motherboard and processor, and even did a clean install of my OS including a format on the hard drive. I am not overclocking anything nor intend to. The motherboard audio is a Realtek device with drivers provided by Asus's support web site but do not use the device at all. I have tried everything I can think of and have a replacement board on the way but am worried that the issue will still be there when I install the replacement board. I have heard I could try to change the PCI latency settings in the BIOS but am unsure as to how to do so or if it's even an option within my BIOS settings. If anyone can please add their input as to how to do so I would greatly appreciate it. Just as well, any ideas as to why this is occurring is also appreciated. Thank you kindly.
