i have a asrock z87 exetreme 4. I just got a graphics card yesterday and inserted it on PCIE2 slot.
Was working great for the whole day. Next morning i power on and nothing on the screen. I go through your typical troubleshooting steps and still nothing. So i decide to put the card in the next PCIE slot and it works again. Is something wrong with PCIE2 and how could i fix it? Also i know that the slot i have it in runs at 8x and not 16x will this affect my performance?

Thanks
