Dolphin keeps crashing

[TomAwsm]

So I've been searching a lot for fixes for this. After playing a game for about 10 mins, I get a message saying "Dolphin.exe has stopped working" and all I can do is close it.

Computer is a brand new desktop with Windows 8.1 x64

Intel Core i7 4790 3.6GHz
8GB RAM
NVidia GeForce GTX 960

All drivers are up to date, as well as Visual C++ and DirectX.

Backend set to OpenGL, all other settings are default.

Happens on all of my games.

Have you tried the latest version?

[TomAwsm]

I knew there was something I forgot to list.

I'm using the latest version.

EDIT: I see now that I had only put 4.0 rather than 4.0.2 in my profile. Sorry about that, corrected.

Just to be clear: 4.0.2 isn't the latest version, he meant the latest development revision. Sorry if you know that already.
