The NV4_DISP.dll blue screen error will typically show for people who want to play the likes of "World Of Warcraft" or another highly-advanced game. Although it will restart your PC and show the dreaded "Blue Screen Of Death", it's actually very easy to fix if you actually know what causes it to show in the first place. This tutorial is going to explain exactly why this error shows, and also how to resolve it in the most effective way.

What Causes The NV4_Disp.dll Error?

The error this file causes is actually down to the NVidia Graphics Driver. This driver is used by millions of computers around the World, and is renowned for helping your computer run extremely high-quality graphics. Although the NVidia graphics is extremely important for your PC, it's continually responsible for the "nv4_disp.dll" error because it will continually use this file in an infinite loop.

Whenever you load up a game, the nv4_disp.dll file will be called to help process all the intense graphics options your system will have... but in the case of your system, the file will either not load correctly or will be loaded over and over and over - crashing your system. The way to resolve the nv4_disp.dll error is to first re-install the nVidia driver on your PC and then fix any part of the program which may be damaged.

How To Fix The NV4_Disp.dll Error On Your System

The first step to repair this error is to restart your PC into "Safe Mode With Networking". This is a mode created by Microsoft to stop any drivers or programs which may be causing a problem from loading. You can enter this mode by restarting your PC, and then pressing F8 continually before Windows has a chance to load. This will then bring up the "Boot Menu" for Windows, and give you the option to load up in Safe Mode or Safe Mode With Networking. You should select "Safe Mode With Networking" and then wait for your PC to load.

After you've loaded up Safe Mode with Networking, you need to then browse to "Start > Control Panel > Add / Remove Programs" and then remove the NVidia program from your system. This will get rid of the erroneous NVidia Driver and replace it with the Windows default driver. In all honesty, you likely won't see the difference, and I would recommend keeping the Windows default driver, especially if you have Windows 7. When the removal process is complete, you should restart your PC and let it boot up normally.

The last step to fixing the error is to then clean out any potential registry errors that your computer has. The registry is a central database which keeps all the settings, options and files for your PC; and is where your PC keeps the likes of your desktop wallpaper, most recent emails and even your stored passwords. One of the most common reasons for Windows to show "DLL" errors is because the registry database will become damaged, preventing your PC from being able to correctly read the files it needs to run. To ensure this problem is not causing your nv4_disp.dll error, you should download and run a registry cleaner program to fix any of the issues you may have inside the registry.
