Just been playing a bit of Dirt 2 and I've noticed that my launch day PS3 Slim is now and again showing up some artifacting. It starts off in the middle as a small vertical line or two, then it grows slightly (more vertical lines from the middle outwards) and then disappears completely and I may not see it again for a while (hours). This has only started happening today and I had a bit of a Google around but it seems to be results with 'my original PS3 is artifacting, I may upgrade to a slim'. Anyone had this issue? The PS3 doesn't seem to be very warm (to the touch) but it is pumping out quite a bit of warm air as you'd expect. It's not in a cabinet or stored away anywhere that would hinder cooling so I'm in two minds as to possibly get it replaced or not. It's a hassle I'd rather not go through but if the thing is gradually toasting itself it'll be guaranteed to go bust one day after the year's warranty expires. I'm assuming I would be within my rights to go straight to the retailer given that it's not that old? Thanks for any help.
