The song is - I guess - from the 90´s or early 2000, but more like 90 something. The video was showing a nerd guy at school, who doesn't have a girlfriend, so he "creates" one in his laboratory, or maybe in the school lab, but then some cool guy steal her from him. Then he creates another one and another one, until, in the end of the video, one nerd girl who was observing him found out and stopped him from creating another clone. So, she actually liked him, but he didn't recognize her before, so she pull his hand back from the machine and smile or something. I think that the main character - the nerd- is played by the same actor who is in Jennifer Paige's video CRUSH. Please, help me! Thanks!
Pulling down the comment by OP to remove this question from the unanswered list.
The song you are looking for is by Aerosmith - Hole in my soul. It was released in 1997 and the music video fits your description to a T.
