Ps3 problems NEED HELP

My name is isiah and i have been getting stressed about this problem.
Okay so I turned off my PS3 when it froze on a game. I didn't really pay much attention to it so I turned it off and did some other things around the house. I turned it on, and all it just did was turn in to a black screen no theme sound or anything I have tried everything i can to the press and hold for two beeps and then to the 2 fast beeps and all it does is do the same thing black screen nothing else I need help!
