3 Beeps Froced Shutdown

Hey guys, I have this really annoying problem and wondering if you know how to solve it.

It's on the ps3 and whenever I play a game, now its inFamous and Wolverine, about 1 hour playing into the game, the console sets of 3 short "beeps" and just switches off while the red light (standby) is blinking on and off.

People have told me to put the console away from a wall because it could be overheating, but I have done that and its not the problem.
If anyone has any solutions on how to fix this and not just call Sony, please tell me.

Also, if anyone knows, if I keep on playing the games and then shuts down and turn it on again over and over, does it destroy the console?

Thanks

Bug reporting is for site bugs I think >_>

Sounds like your PS3 is overheating.

This forum is for site bugs, the PS3 forum is where this belongs.

Make sure you are not blocking the airflow with something, cause this sounds like overheating. 

Hit it with a sledgehammer. Works everytime.
