Mircophone Problems Please help

[2zo]

Ive recently just purchased a new microphone/headset and every time i try to use it, it gives me this weird feedback noise like a radio frequency noise. ive had this problem before with an old microphone i was using and i thought it was just the microphone but now i got a new Logitech G230 and it still has this weird frequency noise. i dont know what the problem is but its annoying and i would really appreciate if someone had a word of advice. 

My computer specs are: 

AMD FX-4130
4GB RAM Crucial Ballistix Sport 1600Mhz

ASUS M5A78L-M/USB3
Rosewill Green Series 530W PSU
EVGA GTX 660 Superclocked
1TB Western Digital Blue
Running on Windows 8.1
