Hello everyone...I have a confusing problem. My computer, an eMachine D2880 w/ a 2.66 GHz celeron processor and 1GB of aftermarket RAM, worked fine until a power outage last week. Now I have a green light on the motherboard when I plug in power, but no fans or beeps I try to turn it on. First, I tried a different power supply, then bypassing the power switch with a jumper, and then another power cable and wall outlet, all with no change. I figured it's the motherboard and so I installed an Intel D865GVHZ. I disconnected everything except CPU, fan, and power and still I have a green light on the board and no fans/beeps. Finally, I have tried a 2.6 GHz Celeron and still nothing. Does anyone have any ideas?

eMachines are notorious for using garbage PSUs...usually Bestec units. "I tried a different power supply, then bypassing the power switch with a jumper" With a jumper? The power switch on a PC is a momentary switch like a doorbell button. You don't press the button & hold it, you press & release. Using a jumper is the same thing as holding the button in & could possibly damage the board or PSU or both.

Even though the power switch is a momentary switch, if you start with a shut down computer and press and hold the power button the system will power on for a few seconds before powering off again. I don't get that much from my system. Even with a completely different PSU if get no fans, etc. Thanks though.

I'm having similar problem. The fan continued to run for some time when I attempted to turn off, I eventually held in the start button to power off. Left for 2 days. When I returned I noticed the green light never went out. When attempting to start I get a lot of cliicking but the fan barely moves. What was really scarry was when I removed the power cord, the green light remained on for at least 15+ seconds. I tried leaving it unplugged overnight while removing all extraneous connections. Nothing! I hope you find an answer soon so I can try the same remedy. Can't run my business if I can't get to the programs and files.

vivbarnett For best possible help you should start your own thread here rather than piggyback on this one. Use a descriptive title and post all your relevant system information and a brief description of your problem, including what led up to it.

I would remove the board and the new power supply and bench test them.......any non conductive surface. 1.It is easier to get at. 2.Board may not be lining up right in the case and shorting out. If you tried the new board out with the old power supply it may have fried the new board. If not yet don't use the old one.
