I was playing with my ps3 and the suddenly it shuts down....and when i ever turn my ps3 on again its shuts down automatically.....

Your disk drive has broken and will need to be repaired/replaced.

I would first try a simple reset. To do this turn the PS3 on my pressing the power button, except hold it down, keep it held until it beeps again and shuts down.

Once it shuts down from you holding the power button, turn it on normally and see if your video settings have returned.

if u were online someoone haked it and toook all your progresse if u see a sudden jump in internet bills stop all conections it will end up costing u up to 7000000 dollers in cash and thts not good people have had this problem before so ur not the only one dont worrie they cannot get ur computer or other things just complete controll orf ur internet bill and your ps3 sorry theres one thing tht will 4 sure work......get the internet shut down and get a new ps3

Turn on your ps3. In the main menu of the ps3 go to "Game Data Utilities". Delete the Nba 2k10 file. It should start playing again and you saved files should still be there.

This is coused by overheating of the console, make shure that
the hot air from in the console can get away and the console
stands completely free so that fresh air can reach the console.

Mate if you turn your PS3 off when the hard drive is still operating or the power shuts of while playing a game and the PS3 is collecting or writing data to your hard drive, it will most definitely corrupt or even destroy your hard drive it is very common in PC's to.
Hint:
1. Do not shut down your PS3 while it is saving a game or collecting info from the hard drive. Rather quit the game then press your off key with one quick touch and let go of it, it will shut down when it is ready or hold down on the remote's PS button and select switch off system on screen.
2. If you live in a area where the power shuts off for no reason please please get your self a computer UPS(UN-INTERRUPTED POWER SUPPLY).
3. If you replace the hard drive make sure you buy a good quality hard drive like a Western Digital or Seagate.

sounds like powersupply is bad. you can find one on ebay for about 40. not that hard to replace yourself. hope that helps.

if it beeps 3 times its probably toast.

How long were you playing it? if you were playing for a couple of hours, then it could of just overheated, in which case the ps3 will shut itself off suddenly to keep from damaging something. It should work after about half an hour, adequate time for it to cool down, if not, then you might of damaged something.

Did you check a fan maybe not working and ps3 is overheating and automatically shut down
