I had the problem for 2 weeks, i reset my BIOS and CMOS, reinstalled drivers many many times and reinstalled windows etc. After a long while with just using the basic windows render driver I decided to try again, while installing the driver the screen went black and the screen said "No signal detected" after this I disconnected the DVI cord from the screen side and after about 10sec plugged it back, and the screen came back with the signal. I heard a sound while installing the driver that something unplugged and when plugging the cord I heard a sound of something plugging.
I think the drivers just messed up the output signal or port, since turning the screen on and off didnt have an effect on it, neither did switching the ports on the GPU.
