Hi,
Recently I started getting these annoying blue screens with the parameters written in the title.
I checked my memory with MS tools and EMM386, and found no errors.
I wanted to eliminate software errors so I reinstalled my OS using an image I took not long ago.
After the installation the problem persists.
The blue screen appears at no special occasion, somethimes even after a restart, I connect to the net, open IE and BANG!
I attached a few minidumps, I hope that someone could help me understand what bothers my computer.

My system consists of:
MB - Asus P4C800 Deluxe
Memory - 2x256MB kingston DDR400 sticks
HD - SATA WD 120GB + IDE WD 40GB
Video Adapter - Asus V9180 Video Suite (Nvidia GEForce 4 mx 440)
Sound Card - Creative SBLive!

Thanks in advance.

All the dumps crash at nltdi.sys, which belongs to Netlimiter. See if there's an update available.

I do have the Netlimiter installed, however it is the last update avail.
I'll check it out with the software developers in search for answers.
Thanks very much!
