Perhaps it would be beneficial to decide what specifically you most want to do. If your 5 months spent job searching have been you informing employers that you're willing to do anything and everything they don't take you serious because you don't specifically want to do the thing they want to hire someone to do. This is pretty much what Patrick said to some degree. If you know what they want and revolve your resume/cover letter around this, it should help a lot. You don't have to send everyone the same resume.

My other comment is your email address. I hope you're not putting "aliengeek4u" on your resume. It's fine for normal personal use but perhaps you should register a second email in some form of your name.
