My Monitors are acting insane

[TheMegabit]

Hello there, I have two monitors plugged into my 2 Gigabyte GTX 980Ti Xtreme Edition Graphics Cards,  one is plugged into the HDMI port  on the bottom card while the other one is plugged on the DVI-D port on the top graphics card. I recently installed the latest nvidia drivers for my graphics cards and now only the one which is plugged into my bottom graphics card works. I plugged in the monitor which was plugged into the top graphics card into the bottom one, but that just made the 2nd one work and my main monitor to stop working, so I decided to keep it plugged in to the top graphics card. I installed drivers for both monitor, by first checking in device manager then downloading the official driver from the websites. In case you are wondering, my monitors are a samsung syncmaster sa300 and a yiynova mvp22uv3. This only happened after I installed the latest Nvidia drivers for my graphics cards, are the drivers bugged or is there some other issue I am not noticing here?

Deinstall the new driver(DDU) and install an older version. I had some big problems in last months with newer nvidia drivers.
