2 years ago I purchased my PC with a 7850 and had all 3 monitors up and running smoothly with little issues.
My existing monitors all HP 2211x and each has a DVI and VGA connector.
SapphireHD7850 has 2 mini display ports, 1 HDMI and 1 DVI
Initially I was using 1 apple MiniDP to VGA, 1 Apple MiniDP to DVI and a straight DVI to DVI to connect all 3 monitors and all worked just fine until about a month ago when the third monitor would start blinking on and off and then wouldnt come back on until I disconnected it and swapped connections between the two MiniDP connectors.
Currently only 2 are working. I cannot get any image on a 3rd monitor. I have tried every setup imaginable. I can only get any 2 monitors to work at one time.
My motherboard is an ASUS P8Z68-V
Any thoughts or advice? Do I need to buy a new graphic card?

I have 3 DVI cables, 3 VGA Cables, 1 MiniDP to VGA adapter (active according to apple), 1 MiniDP to DVI (not active according to apple) and 1 MiniDP to DVI (Active) Accell MiniDP to DVI Active
