My PC does not detect my display


I have a computer and a display connected through DVI. It's been working fine for a long time, but 2 days ago stopped displaying a thing (nobody has manipulated the computer). When I start my computer does not display a thing, and my displays shows ¨No DVI cable detected.¨
My computer has no display connection on the motherboard, so I can only connect via my graphic card, which it has 2 DVI ports.

Things I've tried:
1) Connected to a different display, with a VGA-DVI conversor. The display shows ¨No VGA cable connected.¨
2) Open the box of my computer and checked my graphic card is working (at least, the graphic card's fan is working).

Any ideas? Thanks all

Re: display

The first thing to do with monitor problems is to try the monitor on another PC and another monitor on this PC. Then you know if the (hardware) error is in the monitor+cable or in the PC.

Re: display not detected

If it occurs in both OS'es you can be more or less sure that it isn't a driver or setting issue. And that makes it a hardware issue: graphic card, cable or monitor.
