The process nv_agp.sys is known as NVIDIA nForce AGP Filter that belongs to software NVIDIA nForce AGP Bus Filter. This is driver software, which is a small program that enables the operating system to communicate with the devices that are attached to it, or with the computer hardware. Nvidia supplies graphics processing units (GPU), which are electronic circuits designed to rapidly manipulate and alter memory to accelerate the building of images for output to a display. These are embedded in mobile phones, PCs, workstations and game consoles, and functions by manipulating computer graphics. It is either installed as a video card or is embedded in the motherboard of the CPU. To ensure the functionality of the Nvidia GPU, this kernel driver must be properly installed in the computer. The NVIDIA nForce AGP Bus Filter is an Nvidia card that contains the process file nv_agp.sys that is necessary for the graphics processing unit to communicate with the computer operating system.

Most non-system processes that are running can be stopped because they are not involved in running your operating system. nv_agp.sys. is used by NVIDIA nForce AGP Filter, If you shut down nv_agp.sys, it will likely start again at a later time either after you restart your computer or after an application start. To stop nv_agp.sys, permanently you need to uninstall the application that runs this process which in this case is NVIDIA nForce AGP Filter, from your system.

After uninstalling applications it is a good idea to scan you Windows registry for any left over traces of applications. Registry Reviver by ReviverSoft is a great tool for doing this.

The ReviverSoft experts have not yet reviewed nv_agp.sys

A process usually a part of an installed application such as NVIDIA nForce AGP Filter, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.

We have not received any complaint about this process having higher than normal impact on PC performance. If you have had bad experiences with it please let us know in a comment below and we will investigate it further.

The first thing you should do if nv_agp.sys. is causing errors on your computer is to run a Windows registry scan with Registry Reviver If you are still seeing errors after this you should uninstall the program that nv_agp.sys, belongs to, in this case NVIDIA nForce AGP Filter
