Hi
Does it say no input from the second you switch it on or does it come on and then go off. Did it ever work on that PC and what has changed since then.
If display comes on then goes off - Restart your computer and press F8 whilst booting. Select VGA mode. If you get to a desktop change your display settings to 800x600 to start with and reboot.
If there is no display from the start - and the PC used to work with the card and doesn't now, then the card could have failed, but sometimes they work loose ("heat creep") if you don't mind going into your PC then disconnect all power and make sure your graphic card is pushed in properly..
