nvlddmkm.sys is to do with your nvidia driver, although the crash dump above does reference memory management which is a concern. I order I would try the following:

Change your graphics driver, if you can update it do this. But uninstall the old one first don't upgrade. If you have the latest driver, try removing the driver and software and installing the pervious version. See if this is stable. You need to eliminate a software / driver problem first. If the machine is still not stable try running memtest86+ (google it) you can run this before windows from a memory stick and test your RAM. If your RAM is faulty one pass is usually enough to identify an issue. If none of these things work it could be the memory on the card itself, I am not aware of a way of testing this as I have never needed to... but it might be possible.

Even sometimes I have had RAM errors in the past and powered the machine off, removed the RAM and cleaned the RAM slots with compressed air. Dust can cause havoc inside a machine!
