Serious Problem loading up minecraft

The error comes up in a notepad file in the minecraft folder; it reads:
a fatal error has been detected by the java run time environment.
exception_illegal_instruction

When i load up minecraft (its a cracked version, also tried it on a real version and it still doesn't work)
i press enter game on my cracked version once i've selected my name then it goes to a blackscreen and then closes the game; it doesn't even reach the mojang load up screen.
if anyone could help i'd be extremely happy.

update java
make sure u got the right java 32/64bit version
update ur drivers
