nvlddmkm - WTF?! :dead: nvlddmkm.dll :dead: This little son of b**** crashes my computer just before Vista manages to finish loading. It gives me a lovely BSOD and then the computer reboots. It only happens when I have 4GB (4x1GB) of RAM installed. When I have 2 or 3 GB, it's fine. I have looked on the NVIDIA forums are there are pages and pages of people complaining about this, though mostly because it crashes games rather than prevents Windows from loading. Apparently, o/c'ing your graphics card can make this worse, and at the moment my Gainward Bliss card is o/c'd through its BIOS so I'll have to bring it down to stock speeds to see if that allows me to boot up. Until a fix is found, I'm essentially down to 3GB of RAM on my shiny new x64 installation of Vista SP1. This has being going on for a long time for many people and I see no sign of a quick fix from NVIDIA. I'd be quite interested in hearing from anyone else on OSNN whose had similar problems. Anyone found their own solution? I noticed that apu95 had a very similar problem to mine.
