Look for blown capacitors like RIFA capacitors in the power supply Check keyboard for liquid splits like drinks and\or animals presents, like urine Power - check voltages Power supply outputs On the board, voltage regulators - check regulators specifications for pinouts and voltages Feel - do any IC (chips) feel hot? If so, replace CPU, Memory, Support IC\chips Listen - listen to the boot up sounds Normal start up sounds like on Apple II series, Commodore PET 4000 series, Apple Macintosh chimes. ** Some computers like C64, Timex Sinclair, etc have no boot up sounds.
