Hello, after a power outage two exactly same computers had the same problem. it is two HP 7800 and both have an Nvidia 8400 GS with two screens each. the video card is pci x1 and has a unique port attached to a cable that outputs two vga ports which are connected to the screens but since the outage only one screen works. both computers have the same issue so i checked the screens and they work fine, i checked the card on another computer and it worked fine. i'm not sure what to do next. could you help me? is it possible that the pci slot is not working anymore or there's not enough power for 2 screens or some settings have been messed in the power outage, i don't know what to try...
