Ive been using ue4 for developing for years, but it suddenly stop working last week.When I try running Epic Game Launcher, it wont appear, and when I try launch UEeditor directly, it failed with a message saying “Out of Video Memory try allocating render resource…”.
But my computer is i7-6700K 4.0G/32G/GTX1070 8G, so it should be pretty much meets the requirement.
I tried uninstal the graphic card driver and reinstall it, but it still not fixing the problem.
Anybody knows why this is happenning?

看了下你的log，还无法判断具体的崩溃原因。你有试过把登录器卸载重装吗？另外如果能打开登录器，还可以尝试下修复引擎：

尝试了各种方法都无果，最后我把系统重置了，就解决了……估计是win10的原因。
非常感谢
