nonono i know what to do this JUST happened to my friend
if you turn it on from the back (when theres the red light) hold the power on (on the front) untill you hear a beep
do this 10 times and it will fix itself
this fixes either a fan problem or a harddrive corruption
CAUTION: you may lose some of your saves! you also have to sign back up for psn, but you can use ur other account by useing an existing account
this happens because the resets make the ps3 do a system restoration
hope this helped
