WordPress – Left side of site not visible

This is probably a common problem with WordPress, but I have not stumbled upon a solution yet.

When the resolution on a computer is low enough, the entire WordPress site appears to get cut on the left; therefore, missing out on the left features of a theme or site. I am able to see the entire site at home (1600×900), but my computer at work can’t (800×600). The logo on the top left is cut and the rest of the left side of the site is unavailable. Is there a way to fix this or is it something we just have to deal with? I wish I could post a screenshot, but I can’t at the moment.
