Black un-docked panels / windows multi monitor. Low memory

[pkofman 4]

In the past few weeks I seem to be having low memory problems. I am running three monitors on two video cards 780gtx

 

I don't run them as a surround set up just discrete monitors so that i can undock windows and place them on the screens

 

I am running w7 fsx 1,2 qccel  2x780gtx and 32 gb memory  4770k 4.3 overclocked . The video cards are not o/c

 

The problem is that when running certain aircraft. Carenado/PMDG  two things happen

 

I start to lose textures ( skeleton aircraft , black un-docked panels . Eventually this stop running.

 

Not sure what is causing this but I have started to experience this and nothing has changed.

 

Any thoughts???
