    My screen keeps switching from desktop to black screen and back since installing FirePro W4100


      Bought a Fire Pro W4100 to power my new acer B326HK Monitor.  It replaced a Radeon 4550 that came with the Dell OptiPlex 980 desktop.  Now after only two days of using it the screen keeps going black every 15 seconds or so.  It has made my computer unusable.  Does anyone have any suggestions to fix this.  It has the latest drivers and I have connected the monitor to the card using a display port cable.
