Hello friends!

There are many reasons for the blue screen 7E. I won’t mention the useless ones. They can be found online. The prompt nv4_disp.dll indicates that your N card graphics card driver is If there is a problem, update the graphics card driver and the problem will be solved.

It is recommended that you download and install the driver with Microsoft WHQL certification from the manufacturer of your specific hardware device or Driver Home.

If you really can’t find it, just download a driver wizard or driver life, which will automatically help you find the corresponding driver when connected to the Internet. (Note: Be sure to download and install the (WHQL) certified driver. Driver.)

Appendix---Microsoft's instructions on driver blue screen: The driver is not digitally signed, which means that the driver has not passed Microsoft's Windows Hardware Quality Laboratory (WHQL) testing. Installing drivers without digital signatures can cause the operating system to run unstable and even cause a blue screen of death. You can obtain WHQL-signed drivers from the manufacturer of your hardware device.

Wish you good luck! If you have any questions, please ask. If it helps, I hope you will adopt it.
