HTML/CSS Element lose its position in other computers but not in mine

I'm not sure if the resolution of the screen can affect the CSS. My screen resolution is 1280 x 1024.

Last time, I tried my website: http://alexchen.co.nr/ in a friends's laptop and my webpage and an element (I think is #lang) moved out of place (i think it only happened in Chrome).

In my computer everything is fine (Firefox, Chrome, IE6, 7 , 8, etc.)

CSS (I'm also using Eric Meyer's CSS reset):

I think I in my friend's laptop the horizontal width, padding or margin of some elements was duplicated or something.

I made the text inside #lang a bit smaller, but not sure if the problem still there.

Is my webpage: http://alexchen.co.nr/ displaying correctly in your current screen resolution (IE, Firefox and Chrome)?

If not how do I fix it? what's causing the problem?

Too see what your site looks like for different machines, OSs, and browsers, check out http://browsershots.org/.

I just submitted a job here. Your site loads very slowly (try YSlow or Page Speed to see how you can speed it up) so some browsers will time out before it finishes and you'll see a blank screen.

Try to find out your friend's precise OS, browser type, and browser version. If he's on Chrome 4 and you're on Chrome 5, for instance, results can be different.
