My PS3 freezes once in awhile, not a very frequent thing but it freeze and it kinda piss me off. Sometimes it's only the graphics that's frozen. Having said that, I can still hear background sound, and in fact, I can still navigate it without seeing the screen - I can power off the ps3 from the controller. So far my ps3 had frozen about 4 times since I bought it in december...almost once every month. I'm wondering if there's a fix for it.
