Problem with NVIDIA GeForce GT 330M 256 MB?
I have never had a problem with this machine until 2 months ago when it began to crash badly (black screen) and frequently. I found one answer -- to disable switching between ordinary graphics and hi quality graphics. I disabled the switching so that the hi quality graphics is always in use and the crashing went nearly to zero. I also disconnected the 2nd monitor I was using. But I am still experiencing random seeming crashes and the reports seem to indicate graphics problems. Is anything to be done? or am I looking at a total replacement? (I also took it to the local Genius Bar and as was reported here, their tests did not detect any problem!)
