Hi

I have a GTX460 installed, it has been running perfectly and never given any trouble until today.

I had opened up the computer to give it its 6 monthly clean out as I have already had a very expensive video card (8800GTX)

cook itself.

I removed the 460 without issue (I needed it out to get access to other areas) and cleaned the entire computer out with very low

pressure air. I even lock the fans in place so the air cant stuff the bearings.

I reinstalled the card and fired everything back up only to find I had no display. I rechecked all the connections and made sure the card was

seated correctly but still no joy. I reconnected the monitor to the dodgy standard video out and when I restarted I go the EVGA 460 not found message.

I tried to uninstall and reinstall the drivers and such but it keeps telling me the card isn't there.

 

The computer has had a new hard drive fitted last Friday and had the original C drive cloned over to it. It has been working fine.

I've pulled the card out half a dozen times to look for bent or damaged contacts etc but nothing is visible.

I have this horrid feeling I've some how managed to bugger the card.

did you check wether 6pin connectors plugged correctly?

if yes, can you try your card, psu and mobo in another pc? maybe you have something different problem. a psu or mainboard failure can have occured as well.
