Hey guys I been having problems with my ps3 I got in 2009 and

here are the problems that been go on for two months

1 Corrupted system file

3 Littlebigplanet 2 and remember me freeze

4 today ps3 freeze at start up screen

5 Green light when ps3 is freeze blink like crazy

I´m going to sound like an idiot but why not send it for repairs to a certified Sony technician ? Of course, since I´m not tech savvy that´s what I would do.

Thanks and my ps3 has die it went to console heaven at 10:30
