subject: How To Fix NV4_Disp.dll Errors - Repair Blue Screen Errors Caused By NV4_Disp.dll Easily [print this page] NV4_Disp.dll errors are common on Windows computers because of the way the file it used so much by your system. The file is specifically used by the "Nvidia Graphics Driver" of your PC - a central piece of software which is continually being used to help load up the graphics and files your system needs to run. The error you're seeing (with nv4_disp.dll displayed on a blue screen) is actually caused by your PC reading the file too many times, and sending it into an "infinite loop". In order to stop this error causing any further problems, it's recommended you first ensure that all the NVidia driver files of your PC are working correctly, as well as any further issues with your computer.
The NV4_Disp.dll errors your computer is showing will likely show in this format:
The reason why Nv4_Disp.dll errors occur is because of the way in which your PC needs to use the file to run. The file is constantly used to help control the various graphical elements of your system, and is therefore one of the most important parts of your entire PC. Unfortunately, a small bug inside the file continually makes it unable to load up properly - leading your system to continually use too much. This sends the file into an "infinite loop", which basically causes Windows to crash and be unable to run properly.
To ensure the nv4_disp.dll error is not a problem for your PC, you need to first restart your computer into "Safe Mode". This basically allows your PC to load up without the files and settings it needs to run, giving your computer the ability to load even if it does have this error. When in safe mode, you should then update the NVidia graphics driver on your PC or uninstall it completely. This will get rid of the nv4_disp.dll file, and stop your PC attempting to use it constnatly.
On top of that, it's also recommended you use a 'registry cleaner' program to fix the various errors and problems which are continually leading your PC to crash. Registry cleaners are software tools which are designed to scan through the Windows system and repair any of the errors that are inside the registry database. Although not many people know about the registry (and what it can do for your PC), the fact is that it's one of the most important parts of the entire Windows system because it's where Windows keeps all its settings and options. Most Windows errors have some sort of issue inside the registry, making it vital that you keep this part of your PC as clean as possible, to prevent any further errors being formed on it. You can download a registry cleaner and then use it to clean out any of the errors on your system quickly and reliably.
