Nvidia driver error in file nv4_mini.sys, code: 0x00000050

The nv4_mini.sys file is part of the Nvidia graphics card driver. When this error STOP: 0x00000050  occurs, it does not mean that the error is only in this file. In most cases the problem is caused by the wrong driver but sometimes because of a damage to the vga chip.

First of all, for the problem that causes the file nv4_mini.sys  we have a solution. It’s a solution to the problem based on tests and real facts.

Everyone who faces this problem wants to read the cause and solution of the problem directly. Not to read the blonde blah blah.

So, we are also moving directly to problem resolution in file nv4_mini.sys.

  • First, if you can start the computer and after a few minutes of work appears bsod, I suggest you a test. Immediately after restarting the computer run Gpu test. I suggest you use GPU UserBenchmark. If you can not perform the test to the end because the Blue Screen stops all processes, then you have to uninstall the driver.
  • Uninstall Nvidia driver. First look at the driver that is installed. In the image below is my test.

 

This is the wrong Driver called Nvidia Quadro NVS 210s.  I’ve kept this, just for experiment. And I uninstalled it instantly. Also, do the same thing.

 

 

  • Click uninstall but do not forget to check Delete the driver software for this device.

After uninstall restart the computer.

During the period you do not have the Nvidia driver installed, the Blue Screen will not appear. After the uninstallation you have to identify the model and model number of the computer. You also need to identify the model and model number of the graphics card.

I suggest you using Aida64 to identify device.

 

 

Find the right driver that matches the device and OS, ie the device: Dell optiplex 740, and OS: Windows 7 x86 (32bit). If you can not find it on the official website of the manufacturer of the computer model, then look for the driver in the  official Nvidia website.

After you download and install the right Nvidia driver for the correct Operating System, reboot your computer again.

After restarting, just look for the driver installed. Look at the change in the picture below. The installed driver is accurate and does not cause the Blue Screen.

Right driver
