subject: NV4_Disp.dll World Of Warcraft Error Fix - Quick Tutorial To Fix NV4_Disp.dll Errors On Your PC [print this page] NV4_Disp.dll is a file used by the NVidia graphics driver application to help Windows process the various graphical elements that your system will want to show on screen. This particular file is one of the most critical parts of your system, as it's continually linking your software's requirements to the hardware potential of your PC. Unfortunatley, NV4_Disp.dll errors are highly common with many popular pieces of software, including World Of Warcraft. If you have this error, you need to resolve it quickly and reliably - which can be done using the tutorial on this page.
The errors you're seeing are generally caused by the NV4_Disp.dll file being loaded in an "infinite loop". This basically means that your computer will have some sort of error or glitch which is continually leading it to load up the file over and over and over again. Not only does this make your PC highly unreliable, but will cause the "Blue Screen Of Death" and lead to the nv4_disp.dll error to show. To fix the problem, you basically need to resolve any problems that WOW or your NVidia driver has on your PC.
The first thing to do to fix the nv4_disp.dll error is to restart your computer into "Safe Mode With Networking". This will basically load up your computer without any of the software or settings which can cause it to become damaged & corrupted - allowing you to perform essential repairs. Once loaded up in "Safe Mode", it's then recommended that you then reinstall the NVidia driver on your PC with an updated one from the NVidia website, as well as reinstall the World Of Warcraft installation you may have as well. This will basically allow your computer to run smoothly again.
The second step is to use a registry cleaner program to fix any potential errors that Windows may have inside its registry database. The registry database is an important part of the Windows system because it keeps all the files, settings and options inside for your PC - with everything from your desktop wallpaper to your latest emails being stored in there. If you do anything on your system, the registry is being used to load up the files & settings needed to run... and unfortunately, if any of these settings are damaged or corrupted, Windows starts to show errors. To fix this problem, you should use a registry cleaner to scan through your PC and repair any of the potential registry errors that are on it.
