What could it be other than a head gasket?

I have a 2002 Cadillac Deville Limousine and I just replaced my radiator due to crack. I'm not sure if you're car has electric fans or not.You might to see if there are turning. I'm trying to find out why mine aren't.

Thanks. This last time it really got hot. It told me to turn the engine off and I did, since the battery immediately went dead. I hope I didn't ruin the motor. I'm saving up to get it looked at.
