Black Full screen when starting emulation

[cemecla]

Hello,

I need help with a serious video issue...
I'm trying to make dolphin work on my laptop and I'm having a weird problem.

Everytime I want to start the emulation, as soon as I press the play button, my whole screen goes black and the only way to recover is to power off. No ctrl+shift+esc, no ctrl+alt+del, no nothing. Just a black screen. The computer doesn't seem frozen though so I figure it has something to do with the graphics. Weirdest of all is that dolphin is set to window mode! And it does the same thing with other plugin (OpenGL etc...)

Since my processor is an i5, I have integrated graphics on it but I also have a dedicated Nvidia card, which I want to use for emulation. Dolphin doesn't detect the Nvidia card in its settings so I tried to create a profile for dolphin in the Nvidia control panel, still the same issue. I tried everything I could think of: disabling the Nvidia card in bios, forcing the graphics to run on the Nvidia etc...

I ran out of ideas...

What do your graphics settings look like? When you click on the Graphics button, have a look at the General, Enhancements, and Hacks tabs. Tell us what you have set, preferably as screenshots if possible.

Does this problem occur on other Dolphin revisions, like the official 3.0 release (3.0 without any additional numbers)? Does this problem occur when using the Software Renderer (it's slow, but mostly used for debugging) as your backend?

Additionally, have a look at this thread regarding integrated Nvidia graphics on laptops; it may give you some info you might have overlooked.

Sorry,my bad.

Comodo was the culprit. Defence+ was blocking components of dolphin...

Thanks anyway
