Well here's the thing, I got a GTX 650 for birthday this year and well I installed it as it should. Whenever I turn it on my screen just keeps being black and my monitor blinks it turned on light. I thought it was a power problem so I just went ahead and bought a few more watts (Seeing as it actually needed) well thought that would solve the problem but no, still does the same and when I try to put my old graphic card into it then it does the same, strange. Anyway, hope you'll can help and thank you
we need more system info..the power supply the mb and ram of the system to help.
