Re: eMachine won't turn on
1) Wont turn on at all:
- Test the power outlet with some other electric device for energy. - be sure the power cable to the back of the CPU is well tighten in place. Take it out and look for burnt smell or signs. If not sure try pushing it in and try to turn computer on, try moving it firmly to all directions and try to turn it on to see if the CPU give you life signals or an easier way is to use the monitor power cable if compatible. If you get a intent to turn on from your CPU the is most likelly you have to change the power cable. - If nothing of previous work, you may have a burnt CPU power supply that would cause other damages in your computer depending on the damage. Very often the protections into the power supply block any power line peaks to save the mainboard so you can try to shift power supplies or buy a new one though theres no warranty non any other part of your PC is broken also.
2) Wont show anything on screen, you can hear sounds from the CPU. the keyboard leds turn on, any CPU leds turn on; - Check for loosen video conector. - Bended or broken pins on video conector. - Any loosen card, ram module, conectors inside the CPU (to check into the CPU body you need tools and this can void any warranty)
- If you need clarification, ask it in the comment box above.
- Better answers use proper spelling and grammar.

To do this properly I need to know which model your computer is - is it an eMachines MB.NBK09.003 Motherboard El1850 Desktop S775 G41T-Ad ? I need this to try to establish the BIOS seller and version. You might try finding the BIOS version by (continuously) tapping the F1, F2 or esc key (or possibly another)immediately after you turn on. The "splash screen" that appears aftrer you turn on may have some lettering which tells what key to enter the BIOS.
In the absence of this information here are two suggestions EMachines that beeps constantly and won boot up
if it is the above it is serious and the computer will need serious (difficult) repair, or main board replacement or whole unit replacement (by which I mean new computer)
The other suggestion was about the RAM not being properly in place, but I doubt this as this usually gives a different beep code
Check the power cord at the wall and the machine. Try a different outlet. Check that the power supply dies not have a switch on the back of the pc for a different power setting. If all else fails, it might have a bad power supply.
There are three possible reasons for the issue: 1. Monitor power cable is loose 2. Video Adapter is faulty 3. Monitor capacitor is gone bad
Please try the below steps to diagnose the issue: 1. Check the power cable on the back on Monitor, if connected properly, like connect the power cord on a different Wall outlet 2. Unplug the signal cable from the video adapter and replug it. Also, check a different monitor (if any) on the Tower. 3. If the above steps fails, then the issue is with the monitor, it is going for repair.
your getting power to your PSU, via the green light on your mobo.
verify the PSU has a green light(most emachines do)
it sort of sounds stupid but, check the connection of the cable coming from the front of the case(the wires that connect to the mobo to the power button on the outside of the case.
if all else fails, take the pc out of the case.. put all components on a static free bag and start to rebuild your PC(without a case)
...this will rule out a short on the PC case, and faulty wiring from the case...
pretty much sounds like you've been through almost every step except replacing the PSU(you just said you tested/but your getting power to the PSU)
