Blue screen error

hello I am running windows xp SP2 and I am getting this blue screen error and it shuts down. It seams to only come up when i am on the internet and so i checked the ethernet adapter in the device manager and it says it isnt installed correctly. So i uninstalled it and installed it again and im still getting the error. I logged the error here but its two big to send on here. I remember one line in the error message saying "BAD_POOL_CALL".

0x000000C2: BAD_POOL_CALLER
A kernel-mode process or driver incorrectly attempted to perform memory operations. Typically, a faulty driver or buggy software causes this.

Right now there isn't enough information to tell us what driver is the cause. So...

Examine the “System” and “Application” logs in Event Viewer for other recent errors that might give further clues. To do this, launch EventVwr.msc from a Run box.

well my ethernet controller says it isnt installed properly so im guessing it is that. I have tryed uninstalling it and refreshing it and it does find the driver but it still doesnt install correctly. The laptop I have is a Acer Aspire 5610 I just got it like a year ago not even.

I debugged the error with WinDbg and this is what I got:
