DVI, Monitors, No signal

[Teo_]

Hello every one. I am new here, and i hope i am writing in the right place!
I have a PC which i am using for conference hall. My graphic card has 1 HDMI out, 1 DVI and 1 VGA. I am connecting a monitor with DVI and a projector with HDMI. For more than 6 months every thing was working fine, until 2 days ago. Projector is working well, but the monitor, which is connected with DVI is showing no signal. When i connect it with VGA is working, but not with DVI. (My monitor has only DVI and VGA input).
I would appreciate any help.
Thank you in advance

can you try a different dvi cable? try the monitor on another computer that hat dvi to see if monitor issue or you video card is the problem.
