I really don't like how loud my computer is. It seems louder than when I first bought it. Is there anything I can do to...

You might try running a scan, you may have a virus. If you do have a virus, here are some helpful programs: http://free.avg.com/us-en/homepage, https://www.avast.com/en-us/index, http://www.mcafee.com/us/, and http://us.norton.com/antivirus/

Also, check the battery, it may not be charged. You might just need to plug it in!
