Hello everyone, I'm Joel. I repair computers in my spare time as a hobby... and although I don't consider myself a master by any means, I can troubleshoot pretty well..... just signed up and searched your forums for an answer to this question, but this seems to be something no one I know has heard of, and from the looks of it, maybe not here either, but I'm going to try anyway....... and yes, I have read the thread stating what a piece of junk emachines are. A friend of mine has an emachine. It's a T series, I think 2800 or something like that. Here's the problem(s): She first told me that the computer was booting up normally, but when she got to the logon screen and sometimes just after, the computer would automatically shut-down immediately. By the time I got over there a few days later, she said when she pushed the power button, the computer made sounds like it was starting, but nothing would ever appear on the monitor. When she'd power it down, she would push the power button and it wouldn't turn on at all. In which case, she'd have to unplug it, re-plug it, and push power again.... at which case, the same thing would happen. When I first arrived, I witnessed what she was talking about. Afte that, we pulled the plug (since it won't power down), and when I plugged it back in....... the processor fan automatically turned on and wouldn't turn off. So, I opened it up, and thought it could be the power supply. I replaced it with a spare I had around (and know it works), but nothing changed..... same thing. As soon as you flip the switch on the back of the power supply, the processor fan turns on. I got online w/ tech support from emachines and he mentioned it could be the power switch..... I found it highly unlikely and instead thought that maybe the motherboard was fried..... So, we went and bought a new one and hooked it up to the new power supply....... nothing changed. Same thing happened. I've tore that thing apart up and down, left and right, to the point where I threw the motherboard, RAM, and power supply on the bench and powered up..... same thing! I tried a different case, just to see if it was the switch, but nothing. As I said, I know that emachines are considered junk, but I really feel I've done something, or not doing something that's looking right at me! Any suggestions?
