Ok, this is a bit different than the other topics, and the others are about a year old, so I'm making a new one.

Alright, my problem is that sometimes, after about an hour or so, the screen freezes for my PS3. I still hear the noises from going up and down, it happens both playing a game and on the home dashboard thing. I just got it a week ago or so, so I can still return it (refurb 20gb) for another one. Could my PS3 be overheating? Because I don't feel hot air being blown out. So the fan might not be working, I don't hear a fan either... even when I get real close, just a small whirr. I need to know if I shoul just call gamestop and ask for another, or if i could do something else.

1) Spore

2) Gears 2

3) Megaman Star Force 2

4) Too Human

5) Prototype

6) A mess of other games I can't name right now. @.@
