I agree on checking the console. TEST 50 should give further information about the results of the power on self tests. TEST 0 should run the system exerciser. I'd strongly advise removing the battery. The machine should work quite happily without it except it will not keep time when the power is off and will forget it's boot settings. Check for corrosion on the main board in the area around where the battery lead connects. Check for corrosion on any memory expansion board fitted and see if the machine behaves any better with the board removed. Regards, Peter Coghlan.
