I had this computer for 18 months and all of a sudden it doesn't send any signal to my monitors anymore. The graphics card is a ATI 5870. I have both monitors hooked as dvi. One monitor is using a VGA-to-DVI adapter. However, connecting with hdmi works. I can't seem to figure out what the problem is.
Could you please list all the cables you're using and how many/what monitors you have?
I have two asus monitors(forgot what models they are). One plug is HDMI connected to my samsung tv and it displays correctly. But the two dvi connected to my monitors send no signal. All these ports are from the video card.
