You need to provide DETAILS about your computer (which version of Windows, motherboard and CPU brand/model, amount of Ram and hard drive setup) as well as the video file you are using (which codec) and list all effects you are using
There is no simple answer, especially with zero information
As John says, we need a lot more information to be able to help you.
For general reading on performance in Premiere Pro, you should start here:

For Mac http://mediainfo.massanti.com/
Once you know exactly what it is you are editing, report back with that information... and your project setting, and if there is a red line above the video in the timeline, which indicates a mismatch between video and project
I have a feeling it's not because of my computer, because I imported the same project into CS5 and rendered without any problems.
The Acer Aspire AS85742 does not seem to exist on the Acer web sites or in a Google search, but I suspect it is a notebook. That makes it difficult to analyze.
Ooops, sorry about the typo. Take out the 8. Acer Aspire AS5742-7653
