Why Does My 120gb Ps3 Freeze When I Play Games?

When I play FIFA 10 it freezes when I start a 2 player game.
Also, on COD Modern Warfare 2, the next mission wont load because the games freezes.

I have checked the discs and there are a few fingerprint marks on the back but nothing to serious, is it the discs or my ps3? Should i just return the games?

Please Help!

Suggestion:

try getting your playstation looked at and ur games cleaned if thats still not working take it back
