for some reason my ps3 reads the dics but then freezes and the screen is black..... the controler doesnt even work! please help me or is my ps3 dying?
Might be a corruption which is causing an issue.
Try going to settings and then system settings and then restore default settings (this doesn't delete data).
If that doesn't work then I'd try going into safe mode. You can do this by:-
1. Put the console on to standby so there's a red light on it.
2. Press and hold the power button on the console until the light goes from red to green and then back to red again.
3. Press and hold the power button again until you hear two beeps and then a quick double beep.
That should then bring up a menu of 6 options. Select option 3 (restore file system). This will come up with a message saying that the HDD is corrupted and will be restored. Just press ok.
If that still doesn't work then I'd try a full system restore. (This would delete all data from the hard drive so you might want to back up all your data first). Go to settings and then system settings and then select Restore PS3 system. You want to run a full format.
If that still doesn't work then I'd give Sony a call (08447 360 595).
