Question / Help Black Screen.

So after nearly giving up and trying every "1 stop fix" everywhere I look and nothing working. I've decided to actually make a post.
I have:
- Reinstalled
- Checked for multiple GPU's (Only 1 - GTX 690)
- Changed compatibility mode for Win7 and Vista
- Ran as Admin
- Restarted OBS each time I made a change.
- Tried going to Nvidia Control panel and adding OBS and putting everything to either performance or single gpu\single screen.
- Reinstalled fresh with no setting besides default and setting hotkeys to numpad 1 and 2
- Tried setting aero off and anticheat hook on - Suggestion by video.
- etc etc

I am still getting nothing but a black screen, no video no cam just audio, like many before me. I am at my wits end and just been trying to fix this for 3-4 hours now.

This is me trying to record a window of Dota 2.
I've tested videos in both VLC and Windows Media player, VLC ends up crashing because of it and WMP plays only audio. However the Preview stream works fine.

Enable Aero and remove the anticheat hook from the game capture. It isn't needed with Dota2. In fact, just delete the game capture and rebuild it from scratch.
 
Enable Aero and remove the anticheat hook from the game capture. It isn't needed with Dota2. In fact, just delete the game capture and rebuild it from scratch.
I shouldve added that into the things I've already done. I have reinstalled. Did it from scratch, Added game capture and thats basically it, and nothing. The aero and anticheat hook were a suggestion from a video I saw. I've edited above reinstalling the entire thing and doing it from scratch just to show I've done it.

bump I guess.
so. maybe post another log. lets just say, that I can give better advice if I can see how each thing changes when you've done the changes I've asked then I can maybe suggest something else.

Also this time, post a link to your log from the help menu. when you upload your log, it will give you a link to github that you'll copy there.
