Won't Keep Running!
Upon start-up, blue power light is lit momentarily and emachines is shown across lower part of screen (while dark across the top part of screen). Then screen and power light go blank, for seconds and more often even moments at a time. Please help with any experience with this problem. I hook up a Dell from my second PC and no problems at all.
