How to Fix nv4_disp.dll Error

Reader Question:
“Hi Wally, I have an Nvidia graphics card and I have been seeing the Windows blue screen error since I upgraded my driver. How do I fix this?.” - Gabriel N., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: The Nv4_disp.dll file is used by Nvidia graphics card drivers. It is used to increase the performance of Nvidia components. The update that caused this file to give problems was released in Feb 2010.

The fix for this problem has not been released by Nvidia, but some users have collaborated to fix the problem. Although, installing the latest update to the driver from Nvidia’s own website is your best bet to solve this problem.
