My neighbor has an eMachine and we can't get the darn thing to start up. I press the little power button and it won't cut on. I have looked around outside and in the computer and everything is plugged in correctly. I'm not sure what to do. What are the possibilites? It has a 1.0Ghz Celeron (PIII typle) and 128MB of PC100 RAM. What should I do before she takes it to some repair shop? (never encountered this before...) Thanks!
