Power Supply Issue
Ok - so I bought an emachine computer a year and a half ago and the other day the thing simply won't power up. We had been gone for a few days and the computer was fine when we left but totally dead when we got back.
I confirmed that it wasn't the outlet, the cord or anything else. The computer had zero power. (no lights, no beeps, no nothing)
So I bought a replacement power supply off of ebay. The power supply was not the exact same one as the original but the seller swears up and down that it's compatible. I installed the new power supply and here's what happens ...
As soon as the computer is plugged in the lights on the front of the machine turn on and the internal fan starts running. However, the on/off switch has no effect on anything. The front light stays on and the internal fan just keep running - but the computer cannot be powered down or booted up.
Any ideas as to whether it could be the power supply is not working properly or whether I should be replacing another component as well?
