Anecdotal evidence for sure but considering that I havent had any crashes in any games or otherwise until 5/19, Im going to bet its the Nvidia drivers. Event Viewer shows the same error that blackscreens TW3 for me is the same error thats black screening me during web browsing....all started on 5/19.
Its their drivers and, for whatever reason, they are taking their sweet time fixing it.
Theres a pretty lengthy thread on Nvidias forums, if you care to read it:

Im trying to be patient with them...but its just so frustrating.
