One card always slow after reboot!

[mediafire77]

Hello,

I have a rig with the Z77A GD 65 and five 280x Vapor-X.

One of the cards is always at like 80kh/s when I reboot and start cgminer, even if the monitor cable is connected to that card.
I always have to pull the hdmi cable out and put it back in, retart cgminer and then it works.

This makes remote controlling pretty much impossible since I have to be close to my rig to replug the cable to get the card going and I really don't know what to do. Tried different slots and risers etc, and it's not the fault of the card, since it's not always the same card when I switch slots etc.. Anyone has an idea what to try? Just sticking in a dummy plug didn't work.

Best regards

if same card  can make controllable relay sit in cable for "disconnect" purpose.
