Hello, this is my first post on this board, i've lurked for a while but haven't been able to find the answer to my question so i figured i would join. So here it is: I've got a friends POS emachine. When she gave it to me, she said that the computer powered off normally one day, but the power supply and LED light on the front wouldn't turn off. She doesn't have a switch on the power supply so she turned off her power bar. When she turned the power bar back on, the power supply fan spins, and the LED light comes on, but the computer wouldn't start. So I started in the first logical place, tried a new power supply. Plugged it in, everything worked fine and the computer booted up. Had a drink and said I was a genious Powered the computer down the power supply and LED light wouldn't shut off, and it sounded like the hard drive was spinning too. Hit the power button on the front of the computer but it wouldn't turn off or on. So i switched the power switch on the back and it all turned off. Switched the power switch back on and the computer booted up just fine. Power down and the problem repeats. What the heck is going on?
