Dolphin crashing and locks computer

[Alkemyst]

I have Dolphin 4.0-8305 and every so often the emulator crashes but not only does it crash, my computer crashes as well. I can't access Task Manager or Alt-tab or anything. I'm just looking at a black screen. I have to put the computer to sleep and when I wake it I get an error and then I can finally close Dolphin.

Anyone know what the problem is? Anyone know any fixes. I'm on Windows 10 if that helps.
