Source of the problem
The good news is that there’s one general point of failure that causes this problem – that is a driver(s) problem. I deliberately wrote driver(s) and not just ‘driver’. Indeed the first and most obvious possible point of failure is your Nvidia® display driver; however it might be another problematic driver such as a motherboard driver that might be causing all that trouble.
From some reason your Nvidia® display driver and/or one of your other system/motherboard drivers are either obsolete or corrupted.
How to solve the nvlddmkm.sys BSOD
Warning! - Don’t manually try replace that file under any circumstances by another one. Many users try to download that file from random sites, and then they experience other problems. It just doesn’t work that way.
In order to solve the problem you need to make sure that your Nvidia® display driver as well as all your system drivers, and motherboard drivers aren’t outdated/corrupted, and if so, replace them with their ‘healthy’ and most updated versions.
Doing that manually is a time consuming, too risky, and inaccurate task. (You can never tell which are the most updated and exact required drivers). Anyway, I found that the safest (and by far the fastest) way to replace those problematic drivers is by using a reliable drivers repair tool.
To summarize - in order to repair this nvlddmkm.sys BSOD run a quick drivers scan and at the end see which drivers are causing this error, then install their latest, official, and most updated versions.
