MacBook Pro 15" stuck on white screen Apple logo + Weird pattern/color

My macbook wont boot up anymore and it is stuck on the white screen. it has this weird pattern color (the apple logo looks greenish) on the white screen.

I did my research and tried several things;

-restart SMC

-restart PRAM

-Run Disk Utility (CMD + R) whenever i run the Disk Utility, the screen pattern dissapear, the grey screen looks normal I dont have those weird colors anymore. I tried to verfy my disk but it found some errors

-Safe boot (SHIFT)

-Verbose Mode (SHIFT + CMD + V)

-Fsck (CMD + S): I typed: fsck -fy in the command-line prompt a couple of times but not luck

-Reinstall Lion in Disk Utility: I can not reinstall Lion OS because it doesnt allow me to select my hard drive

I have problems with my battery allready, it heats up really fast and blocked my trackpad, I cannot click anymore.

Did my battery damaged my HD or motherboard?

Is there somebody who knows what I can do?
