Your post is a little vague, but I'll try to work through it. Does the second sentence imply that you a) tried shutting off the computer or b) exiting the application? If a), how did you do this, hold down on the power button for 5-10 seconds or just tap it once? If b) were you trying to click the red dot/x in the upper left or Force Quitting 
apple:+option+escape)? To shut off the computer completely you will need to hold down the power button, and to make absolutely certain its off and not just idle/sleeping, its not a bad idea to remove the battery and the power adapter as well. Let the computer sit for a good 5 seconds before putting the battery back in and reconnecting the AC power. Start it up, see if you can login. Try launching Safari, see what happens.

I don't even see the mouse in the screen when i move it. i don't see the dock or anything. It's just a blank screen that's BLUE.
Try the battery trick, then see if the computer starts up normally. You should hear the startup chime (bong) as it starts up.
