I did a search, on google, for "sensfilt.sys" and didn't come up with anything.  Are you sure that is the exact fille name?  Usually, google will find something about files. 

Many games require Direct X.  Go to Start/Run and enter dxdiag  then click OK.  It will bring up the Direct X diagnostics.  It will list what version you have (I think 9c is the current version).  If you don't have 9c you can download it from Microsoft.  You can run the direct x diagnostics and see if your sound card passes those tests.

You should also check the gaming section of the forum, as that is a section for gamining problems.

Yup, sorry I did misspell it, its actually senfilt.sys but don't bother googling it. I am very familiar with pcs and gaming so I looked over the more apparent stuff already like directx etc.. Other directx 9 games will usually run fine on my pc (except one or two that crash once in a while always with an audio related error as I mentioned before). I will go take a look at the gaming forum though, thanks.
