So I have my 9500gt with my dvi connected to my monitor this morning and the monitor just blink analog to digital and vise versa and it shuts down with the power indicator blinking. I also connected a vga from my monitor to my onboard graphics card and it works. The vga is in analog. Whenever I press the source button on my monitor to switch from analog to digital, which is my gpu, the monitor just blinks the power indicator after displaying the analog/ digital thing. What is exactly my problem here?
