My PC spec is below.

I'm getting an error with nvlddmkm.sys which is crashing the computer. Looking at various fixes online (including this very forum) they mention removing the graphics drivers completely (which I've done) and locating "nvlddmkm.sys", renaming it, then reinstalling the graphics driver from scratch.

Unfortunately I can’t find any file named “nvlddmkm”, nothing on my boot C drive *at all*. I've also scanned the other HD's in my computer and that file does not show up.

Even after removing and reinstalling the graphics drivers I still can not find anything named nvddmkm - this is even with it being reported in Event Viewer!!!

Any ideas please?

Solution
Go to control panel->system->advanced system settings->advanced->startup and recovery->settings and then under write debugging information, select small memory dump and hit ok and apply. Also where you selected small memory dump, then go to C:\Windows and after you crash, get the memory.dump file from there. You can either post it up on something like dropbox and post the link here or you can open it yourself using bluescreenview or a similar dump file reading application to get the error codes.
You are right in that this is an issue relating to the nvidia driver, but what in particular is hard to say from just the name. When you use DDU to uninstall current driver, prior to installing drivers anew, make sure you pick a stable version...

When you use DDU to uninstall current driver, prior to installing drivers anew, make sure you pick a stable version of the driver to install on your systm, that's recommended by nvidia for those who are having trouble. Sometimes latest driver versions aren't always the best.
