Can't open RPCS3

When I open nothing appears, when I click on it again an error stating that it's already running. When I check on task manager I saw RPCS3 running as a background process, when I end it and launch it again, it'll repeat the process all over again.

This is due to to you having broken video driver entries in your system.

To fix this:
1. Remove your video drivers using DDU http://www.guru3d.com/files-details/disp...nload.html
2. Remove also AMD / nVidia drivers if you have switched your video card recently
3. Reinstall the latest version of your drivers
