Hi, that buzzing sound you hear can be cause by electricity and it's perfectly normal, unless it's louder than usual. You can fix that by doing a power drain (Turn off computer, disconnect the AC Adapter, press the power button for about 20 seconds - the computer is not expected to turn on, reconnect the AC Adapter)

I really didn't understand this part: " when i look in the back there are little blue flashing lights inide the machine whenever i touch the back of the machine." could you elaborate a little please?

I'll wait for your response.

Ok 1st thanks for responding and 2nd on the back of the pc you can see inside of it kinda and it looks like blue leds are lighting up

yes, that is the hard drive led, it's blue and you can see it thru the little holes in the back . That's completely normal; nothing to worry about.

1 More thing the alien head isnt turning,I dont know if it is brokon or what can you please help me this is my last worry!
