I had a look online. Both games you mentioned have black screen issues for a lot of people. For some its solved by updating flash, others by changing resolution to 720p and then back to 1080p, for others it was adjusting their monitor from 59 to 60 ghz...but I dont think it's a problem with the card or other hardware if other games are running fine.
