Is my PS3 dying?

[PEDXING]

Over the past few months I've had some weird technical issues with several games, but only these specific games, everything else works perfectly fine.

In inFamous and Motorstorm Pacific Rift there were weird lines that would come out of objects in the game, for example in inFamous where ever there were a stack of barrels black lines would jet out from the edges of the barrels and continue on like a horizon line, same as in Pacific Rift.

Red Faction Guerilla and God of War Collection just keep freezing on me whenever I get to the same point. The game will stutter once, then freeze, but the music keeps going, and then it won't even let me go back to the XMB, I have to manually turn of the console itself.

Then last night in the new LBP Pirates level after I got the two coins for the pirate with one eye these giant triangles would pop up and jet around covering like 80% of the screen. The triangles kind of looked liked when there's glass or ice in front of Sackboy, but it was jittery and over almost the whole screen.

Has anyone heard of any of these problems or know what it might mean? I'm using a 60GB I've had since laungh. Sorry for the long talky post but thanks in advance!
