Well today when I turn on the pc my monitor turn black at some random moments, the light that said is it on still blue and no red ( RED is when it have no signal), but there is no image. so i have to turn off the monitor and then turn it on again and the image will show again, is rlly strange. Then at another random moment it will turn black again.
The only change close to this problem is that i started using a Nvidia 970 like 2 week ago. Before i had a 560ti had I never had this problem.

this monitor also have a RGA input i tried it to connect the TV signal to the monitor via RGA and it works! not random crashes. also i connect and old monitor the the nvidia 970 also no crashes! then i connect the monitor with the problem to an old PC and it had the same problem.

what should i do? i think is the VGA input.

My monitor is a LCD 22” with RGA and VGA inputs 1920 x 1080
 


but then why the RGA input have no problem?
