My Macbook is making weird noises. Could that be affecting my wifi signal?

You know those noises your macbook hard drive makes when you boot it (duh-da-duh doo-da-dut)? My system starting making those noises randomly when I use my computer two or three times in a row. Also around the same time that started the wifi connection started to get really spotty. I can connect for 30 seconds and then nothing for 30 mins. Could these issues be related? And should I go to the genius bar?
