Theme Resolution Help !

[Naan-Kadavul]

Hi All,

Recently I have customized a theme for my site. I noticed that my theme doesn't fit all computer screens (monitor). I went around asking people that whether the site theme is fitting the screens or not. 30% of users told me that the theme is not fitting their screens. I have installed 3 Themes in my forum. But they have no problem with the other 2 themes.
The 2 themes are fitting almost 99% users computer. Only the current theme is having problem now.

But its fitting my monitor perfectly. Please guide me in this. I have no idea on how to make the theme fits everyone's computer perfectly. Tried both in firefox and IE. Still the same.
But its working fine for me. I am having
