I have a Gateway E6300 (with an Intel Motherboard) and it has quit turning on. When I press the power button, the fans and lights come on and does nothing else. The screen is black, fans do not quiet down, etc. I have tried unplugging everything except the front power button/light, P4 connector and power (24 pin connector) from the motherboard, and having just 1 stick of ram, with a ps2 keyboard and monitor hooked up(and power). Same. So I took all the sticks of ram out of the computer to see if the motherboard's speaker would beep to indicate no ram. It didn't. How do I tell if it is the motherboard, or the CPU (a P4 at 3.4ghz, socket 775) that is bad?? I think it may be the mb but I really don't have a clue.
