As I said, my PS3 had no previous problems before Skyrim, and there's a reason why i'm not the only one experiencing game freezing, except this my case, it was a little worse.
I did read your previous posts. The fact it was playing other games is irrelevent. While Skyrim may have attributed to the system failure (corrupting files), it did not cause the failure. Games do not cause system failure.
If the system is under warranty, get your replacement. If it is not, these systems only seem to run an average of 2 years so... it was on it's way out anyhow. Mine is crashing more and more right now, is it the game? No. How do I know this? My system has been aging, although it is new, I get odd HDD clicks, fan buzzes, and odd hums at times. Noises of failing components. This browser also causes quite a few (way more than Skyrim) freezes and crashes. System was bought new as system bundle with Killzone 3, so still under a year old. Due to all of this, I know it is not Skyrim that will cause my system's death, but it may be making a contribution.
