HDD beeping... Theory

Ok now i know hard drives can fail at anytime even if they are new, however i have heard a beeping/sweaking sound from my HDD a few days ago after about 2 months of use. it mainly happens when i log into windows (not during the booting process) and can happen randomly during normal use. I have run check disk and seagate diagnostics tool and both report the drive to be "fine" and aswell computer management says its a "Healthy drive".

My theory; a few weeks ago i moved my PC near a tv aerial socket, i then moved it closer to the socket a couple of days ago to free up some space. When the computer is on i sometimes recieve bad reception from my tv on certain channels, most channels are fine but i still hear the beeping. tonight the signal was terrible so i turned off the computer- the tv signal was fine again. i have moved my pc back a bit so will test it tommorow. but...

Question; if my computer disrupts the tv signal (on some channels)- could the tv signal disrupt my hard drive causing the beeping sound?

I know this is a little far fetched but i really cant be bothered to send the hdd away to recieve a new one... lol
