It's a pretty basic option that's not going to cover all instances. What exactly is "computer noise"? Knowing what type of noise it is will be helpful to get recommendations for what might fix it.
It's a shame the audio is noisy (not isolated from noise generating components like fans and optical drives) on may PCs and laptops. My Windows 7 Ultimate PC designated for audio recording is quiet in the recording but the Realtech audio card produces residual PC noise on playback.
If you can export the audio track as a WAV file and run it through a 3rd party audio program for cleanup. and then import it back into your project. It really depends on how bad it seems to you as to how much trouble you want to go.
A number of folks here use Audacity because it can be downloaded and used free. I don't have direct experience with it as I've been a Sound Forge user for 15 years. If you Google 'audacity noise removal' you will see a number of options to explore.
Typically the process is to isolate a 'noise print' in a file portion where there is only the noise to establish what the problem sounds like and then it knows how to treat the entire file. Then bring that back to your clip bin and replace the original.
