I have a GTX 780, when i start my computer i can see the windows logo, but after this, when the Full-HD resolution comes up,i can only see pixels with colors: Red, Grey,Pink,Black,Green,Blue & white. I removed the card, used the on-board card and it worked properly. So i place my 780 back inside to double check that it's broken, but it started properly(did some restarts and it works properly).
Is there any possibillity that the power cables were not plugged-in in correctly or is my card going to die soon?
EDIT: #SOLVED
Just a 2pin cable is being pulled and it disconnects from the card... (corsait plox) - trying to find a way to keep it plugged-in
