No output from any graphics card in my AGP slot

After vacuum cleaning the inside of my computer, and fitting an extra case fan, I get no output from my graphics card. I have tried 3 different cards with the same result

Have you checked all the cables, you might have dislodged something else in your PC.

I hope you didn't let the vacuum touch any part of the inside of your PC as they build up static and its possible that the static can have destroyed some of the components.
Don't panic yet. The most likely thing is you've dislodged some of the cables. Remove and refit them all and see what happens. Have you experience with fitting/refitting graphics cards as they need a pretty good push into the socket to make proper contact. Also what does the computer do when you fire up. Do the fans turn, does power go to the hard drives motherboard etc? I assume from what you say everything seems to fire up but there is just no display.

try disconnecting the new fan just in case it is shorting out.

OK I have checked all the cables, the fans turn, the hard drives seem to have power as does the main board. I have also disconected the new fan, but still no video output. I am thinking of replacing my main board with another I have just found in my loft, maybe this will work.

If you have a spare power supply put that in first before changing the mother board as it is easier and it could be the voltage supply for this to mother board that has gone. It happened to me. Think it is a 3v supply on one of the pins from the main power cable.
