Try your old card again?

 

This sounds like a case of a bad GPU or a badly refurbished GPU that you bought. If swapping out the GPU with your older card works and swapping back the replacement you bought still does the same results you can factor it's a bad GPU and you should get it RMA asap. That problem your describing sounds like a dying GPU not something a new GPU should do. Going white unless it was damaged or old shouldn't happen in new GPU that works. It would be good if you could provide a link as to the exact GPU you bought so other can see what the seller actually says about it to get a better idea where your coming from.

 

I got my 780M to work. I will post some instructions someday
