PC won't boot - Gainward FX5600 looks to be the reason

[mrfrogger]

Hi,

I've been given a supposedly working gainward FX5600. I've plugged it into my motherboard with an integrated intel i810 video which I use normally.
However myy computer doesn't seem to boot. the fans start spinning but I don't get any output from either video output.

Is the card just fragged? (quite likely, it's a freebie) or is there some sort of clash that I can resolve?

Cheers,

Turn it on and leave it for a moment, if you hear the hard-drive making noises then it shows it is booting. If so, try going into the BIOS and selecting the first display device as AGP.
