What is wrong with my ps3?

May be...

when I tried to last night it wouldn't load any games and when I restarted the ps3 the screen was flashing different colors and it just froze it did it twice 2day and it gets hella hot hella fast.

The system ha a overheating problem try to keep it in a cool open area an if the preblem keeps persisting you want to see if you can bring it in for a warrantee or you need to just go get another.

place it in a cooler spot
