my compaq has been trouble free until yesterday. i did a restart and it just set with the fans running. i could hear the hd find its home track. no disk lights no buzzer. if it sets turned off for 1/2 hour it will restart and run fine untill turned off again. the sensors show the voltages and temp are fine when running. all connectors have been reseated. no componets feel hot not even real warm.
any idea apperciated.
