This infection is not so?

There is a PS3.Today, the beginning itself is included.I disassembled it and there:the mother– dust the car and the cart.Cleaned.Chips dried up thermal grease,has struck,has collected.Run...To the main menu comes without problems,but should run anything... Black screen,and the light was green and she was working. This infection is not so?









In the course,something broke.Just climb in the main menu,and she passed out,but the red light was burning.I read a little in the Internet,they write,they say the HDD is dead.So I not only game can not run,I elementary to PSN can not enter and run the YouTube.What is it?Overheating?So I cleaned it
