Grow up first of all buddy, were here to help problems not be an immature goon like yourself..
Second of all, this could actually be an issue if it turns out this happens to more then just your PS3 and the issue itself actually comes from the game.
Was your Playstation 3 well ventilated, is dust noticable on the back of it?
How long have you had your Playstation 3?
What is the model?
Can you explain exactly what happened?
Is it responsive when you hit the "on" button, if so, what happens?
Was there any USB connections in the Playstation 3?
Please approximate how many gigs you had before/after installation.
Is your playstation standing in an upright position or is it laying down?
