I have an Emachines W2686. For a while it would work fine, smoothly, and efficiently. But just recently it decided to REALLY act up. When I turn the tower on, it sounds as if everything runs smoothly. Hard Drive, Fans, Power unit. But it doesnt seem to be reading at all. Ive checked and changed the memory, checked the hard drive, unpowered it for a day, and yet nothing. It still turns on, but just doesnt read it. Ive even switched out monitors, checked monitor connections, and changed the cords. There are lights, for example, the smart card light is on, the CD light flickers, (no cd), and below the power button, a orange light flickers once in a while. The main power button, that usually turns green, stays off. I know my first mistake was getting an emachines, but is there any possible way to fix this? Might it be the Motherboard?
