[Emachine C2684] Systems appears to be getting power, but won't boot.
Greetings all. I'm in the process of trouble-shooting a friend's emachine and looking for a bit of assistance diagnosing the root problem.
Symptoms: As soon as I connect the power cord to the PSU, the CPU fan immediately starts running and the green power LED around the switch lights up. However, no matter how often I press the power switch or how long I hold it in, there's absolutely no change. The only way to shut off the machine is to unplug the power cord.
I've gone ahead and removed everything from the system except for the CPU and PSU and tested powering up piece by piece. Each time has the same result as mentioned above.
My research on the net so far suggests it's either a motherboard or PSU related issue, but perhaps I'm overlooking something?
Any and all assistance is sincerely and truly appreciated.

Track down the motherboard manual, the motherboards of branded machines are usually made for them by PCChips or Foxconn or someone similar.
In the manual identify wich connectors on the motherbaord is the front power switch. Disconnect the front power switch and plug it all abck in again to see what happens with the power switch disconnected.
If you feel brave enough you can momentarily short the motherboard powerswitch connectors and the machine will start.
the front power switch is a momentary switch so only short the motherboard pins long enough for the machine to start.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Step 1: Most people who own an eMachine computer will find that they will need to reset the computer at some point. It is a fact that PCs are more prone to viruses and malware than Macintosh computers. Sometimes the only way to restore an eMachine is to simply reset it. Fortunately, it is not a difficult process to reset an eMachine computer.
Turn off the computer. If the computer is in a state that it can be properly shut down, follow the normal shutdown process. On the other hand, if the computer is not reacting to anything, simply pull the cord from the wall. Restart the computer. Plug the computer back into the wall and press the Power button. Wait for the eMachine to reach the screen that reads "Press F11 to start recovery." Once this screen appears, press the F11 key on the keyboard multiple times to make sure that it registers. If the recovery screen does not come up, you will need to turn the computer off and back on again and attempt to press the F11 button again when the prompt appears. Select the proper option. After the recovery screen appears, there will be a list of recovery options. Scroll to the option that says "Full System Restore (with Backup)." Choosing this option will copy all of the contents of the hard disk to the c:\\My Backup directory. This will ensure that important files that have been created on the computer will not be deleted. However, the applications on the computer will need to be reinstalled. Allow the system restore to run its course. Depending on the age and effectiveness of the eMachine computer, it is possible this process could take up to 45 minutes. When the system restore is complete, the computer will restart itself. Reinstall applications. Any of the files created on the computer should be saved. However, the applications that created them need to be reinstalled. b>
You may need to check to make sure Windows XP was installed properly, if the computer had crashed, you can do a repair, I am a computer technician, and I can tell you, that replacing the power supply will not do that.
Well I can't exactly get you the layout of the motherboard because I don't know what motherboard you have. Find out what model the emachine is and Google it. You'll find everything you need out there. Or you can e-mail the model name to me and I'll help you out: firstname.lastname@example.org
There should be 2 thumbscrews on the back part of the case where the side panel would slide back and off. On some other cases, there is a button on the bottom you need to press to have the side panel swing open.
A C100 error is a registry error. I suggest that U format the drive and reinstall the 98SE. There are programs (bought) available that may fix this problem, but another perferred choice would be to purchase a XP operating system. Boot up on the XP cd and replace the 98SE with the XP. It's better, faster, prettier and more reliable.
Do you hear the system POST (Power On Self Test). In layman's terms that's when the system beeps and does a systems check. If you don't here this, the motherboard is usually dead. It could be another component though.
So, if you disconnect everything externally and internally down to the CPU and a few RAM chips (only what's required to do a POST) and a keyboard, to then see if it POSTs.
If it doesn't POST, then, if possible, try a new CPU, RAM, and Keyboard, other than this, you would replace the motherboard.
If it POSTs, you need to let us know how far it gets in the boot process and what error messages appear. If the boot is short of successful, you can still do the same things listed above to see which component is failing. The replace it. A process of elimination.
