Windows 10 not detecting G card

[Freestyler323]

I have recently upgraded to Win10, and when I did I ran the PC for a week or two off the on-board graphics. I have now been able to get my main gfx card card out of another older PC into this one – its noting special – gigabyte geforce 560. I plugged it in to the MB and noticed on my new PC its 750W psu has an ‘8-pin pcie’ plug. I plugged in the 6pack, but the separate little 2 pin plug didn’t feel as though it wanted to go into the cards other 6 pin port (it has 2 x 6 pin power ports). So I left it off, and plugged in another 6 pin plug from the psu – I think that’s ok?

The card now fires up when the PC is switched on, fans start and lights appear etc. when I logged into windows, windows update started downloaded drivers for the card, so clearly windows has detected it. This process completed successfully, and I imagined it then would have been a simple case of rebooting with the monitor now plugged into the 560. I tried this, but I get no signal on the monitor. I have had to go back to the on-baord to get a signal to my monitor.

Ive tried a second spare screen, same again – no signal for the 560.

Even in device manager I get no entry for the 560.

Am I missing something here? is it lacking sufficient power, or is windows 10 just not liking it?

Any help very much appreciated.

I've done some tinkering in the bios recently to speed up booting etc, but i dont recall ever making any graphic card changes - are there some that need to be made?
