I just built a new machine with an ATI Radeon 5850, a Gigabyte GA-X58A-UD3R motherboard, and a displayport monitor (Dell U2311H) which is connected via a displayport cable.
The problem I have is that when I switch off the computer, the system is still receiving a small amount of power through the displayport cable.
I have verified this by disconnecting all the cables from the computer (including the PSU cable) except for the displayport cable, and the keyboard lights are still on, as is a fan control unit, and various lights on the motherboard. As soon as I take the displayport cable out, all the lights go out, and go back on again when I plug the displayport cable back in.
If I connect the same monitor via a DVI cable this does not happen.
Unfortunately I don't have another displayport cable or displayport capable monitor to try to isolate the problem further.
Does anyone have any suggestions as to why this is happening?
Thanks
