ITunes opening when I wake/turn on my PC?

Hi, Recently whenever I turn my computer on iTunes just quite happily opens, also when my computer goes into sleep mode and I wake it up iTunes opens, It's very annoying because I buy a lot of things on my iPhone and never download them on my computer. Anyways it slows EVERYTHING down. Does anyone know how to fix this. 10 points for best answer, Cheers.

  • Why doesn't my iphone's sleep/wake button not work? So my iphone's sleep/wake button feels weird.whenever i push it, it feels like i have to push it harder for it to work. Can i fix this by myself or do i have to get it repaired? And if i do have to get it repaired, how much would it be because i don't have warranty on it.
  • What is a good country song to wake up to? With the new iOS 6 update for the iPhone, one can set a song as an alarm. All I listen to is country but I'm having trouble compiling a list of good songs to wake up to. Any suggestions are awesome.
