I have a problem w/my G5 games

I cannot get into my g5 games. When I go to the games and click on them it goes to the blue G5 screen as it always does but, instead of going to the continue to game screen it juat stays on the blue screen and I can't X out that screen . It's doing it on all g5 games I'm playing too, mahjoun , mah. Egypt, mah. Rome, mah. Wild west, jewels of Egypt, Rome and, Wild west, Supermarket mania and wordplay. This goes on all day then sometimes around 10 pm it will let me in to play all the games until I stop and go to bed, but when I get up and try to enter them again it won't let me all day long again
