PS3 not booting after black screen error

After about 2 hours of playing my ps3 blackscreen suddenly appeared, so shut it down let it cool down for the day. Tomorrow morning I tried it again and it worked normally again but after i choose a game saved in my ps3 the blackscreen appeared again. But this time after i tried to restart it, the screen does not show any image, it does not detect the hdmi cable plugged in the ps3 to the TV. I tried what they call the recovery mode and safe mode but it does not work. I tried to press and hold the on/off but all I can hear is two single beep. One for turning it on and then it shuts down after the 2nd beep. I dont know what other reason for my ps3 to fail but Im sure its not overheat because I let it cools down before I try open it again.
