There even was an extended repair programme for that: MacBook Pro (15-inch, Mid 2010) intermittent black screen or loss of video Quality Program has ended - Apple Support

install the OS that came with your computer when it shipped and you will have the correct driver, otherwise the 2010 MacBook Pro came with the GT330M and it is a system eligible for OS 10.11 so the driver should be bundled with 10.11
if you are installing UNIX drivers from Nvidia's site that is not from Apple and it's not QC'ed by Apple so whatever you are experiencing would be an Nvidia development issue or If there is a problem with the card itself it may be able to be diagnosed by Apple at an Apple store, but since the device is out of warranty this could be costly to replace if the problem is the card.
Would something like this reduce the strain on memory and eliminate the issue?
NewerTech USB 3.0 to DVI Video Adapter.
My RAM is already at max 8GB, would upgrade to Solid state hard drive reduce memory strain and issue?
