Need help fixing error message....

Hey guys.

I frequently get the following error dialog box pop up when I boot up.

I have a Dell Inspiron 9100 Laptop, WinXP.


"ATI video bios poller client: ati2evxx.exe – Application Error

The instruction at “0x00439d76” referenced memory at “0x00450080”. The memory could not be “written”.

Click OK to terminate the program
Click on Cancel to debug the program"


I have tried updating the video card drivers but my computer says that I already have the most current version.

What should I do??

Thanks!
