Amiga 3000 CIA issues

[Greywolf12]

I'm having problems playing games on the a3000 as soon as I load one the pointer goes to the top left corner of the screen,  thinking this was a cia issue when the game initializes the joystick I switched them around to see if I would get different results, and I did everything worked for about 10 min then started doing the same thing just not as bad.  Any ideas...

It looks like it's Heat related,  Let it sit for a couple of days went back to it worked fine for 10min then I got the same issue with the joystick, mouse works fine mouse buttons seem to be hit or miss after 10min also.  So how do I fix this heat issue???  Oh and the games are Wings and Bally III
