I had an MSI 7850 installed in the system for well over 12 months without any problems, turned on one day and there was smoke and then no display so turned off the system sharpish and removed the GPU. It was sent under RMA and I have received a HIS 7850 as replacement.

I put the new GPU in and get no signal, also the card is not being detected in device manager. There seems to be powergoing to it as when I boot up the fan on the HIS seems to ramp right up.

All drivers are up to date so could the old GPU have damaged the motherboard ? The PC works fine with the onboard graphics.

The smoke suggest that there was some kind of power surge or something which blew the card. What PSU do you have out of curiosity? Its rare that a card would go up in smoke on its own so although the first card failed, the fault might be somewhere else.

Have you tried a different PCI-e slot?
 
Think you might need to update your motherboard bios in order to detect this particular 7850 unfortunately.

Also as above, try a different PCI-E x16 slot...may be the original slot got damaged.
 
Cheers fellas, finally managed to get it to work but it is using the PCI Express x16 slot, running at x4 (PCIEX4). Have spoke to overclockers and they have said it wont really make a difference running it in that slot.

It turns out that my PCI-E slot the old card was in is borked.
