If you restore your ps3 system it will clear you HDD, just want to make sure you know that.
You can try to restore your ps3 system like this it might fix your problem.

1.)Turn off PS3 so the red light is on.

2.) Hold and keep holding the power button. The console will turn on, and eventually turn off again.

3.) Once off, with the red light on again, press and hold the power button. You will hear one beep, another single beep after that, and then two beeps in a row. After the two beeps, let go of the power button so it doesn't turn off again and you'll end up in the system recovery menu.
