You say it like PCs never get overheated or crash. I've had to change my PS3 2 times because it was overheating and crashing. I followed every tip there is to follow on the PS3, it had lots of space and all that. Could be anything. Your room could be dusty or moisture, for example. In Norway the air is very dry, the living room was no exception. And I was living with my mom, who cleaned the house at least once a week. I doubt it was either dust or moisture.
