I have the same issue. Event viewer just lists it normally as an application shutdown (event 1000, which it lists whenever a program closes unexpectedly). It's been worse since the February patches too. I approached SE tech support and they had no solutions. They suggested not running any other programs, reducing graphics settings, a fresh install, updating drivers and none of it worked. Then they admitted they are working on stabilising the game for the next patch, but couldn't promise anything. They even said if a system meets the minimum requirements, there's no guarantee the game will run depending on other software installed :/ Not very helpful...

Personally I'm just going to wait and see.
