Did MGS4 kill my 60gb or can it be saved?

I have two friends whos 60gb ps3's have failed. one was within warranty so he had a replacement with a couple weeks. the other one's ps3 was out of warranty and I convinced him to pay the $200 something to get a replacement, this took a little longer though (he was planning on pay $550 for a new one). they both got 60gb units as replacements (they both had launch units to begin with).
