It's an emachines about 3 1/2 yrs old. I already tried changing the power supply, but it does the same thing. The green light around the power on/off button on the case is lit but nothing else is working. No fans, no hard drive spinning. If the motherboard is fried am I better off to find an aftermarket replacement or junk the whole thing and buy something else? I put a new power supply in this computer about a year ago, and for the last month or so it has been doing strange things like not recognizing my ipod, freezing up, and finally it froze up shut itself down and won't power up again. Also, if the board is fried, is it likely to have fried the processor with it?

Emachines are known for their flaky motherboards. Try resetting your bios with the J5 jumper on the board. --unplug power to case and put the jumper on the other set of pins(ex--if on 1-2 switch to 2-3) for about 20 seconds then move it back to original position. Unplug everything but the hard drive and the video card and try to boot. Sounds like youre right--most likely the board is gone. CPUs are usually ok when the board fries. If it is and you choose to replace the board get one with the same northbridge and southbridge chipsets. That way your puter has a chance of booting as your hard drive has the drivers for those chipsets on it and if you use a different type board you may not be able to boot at all. If you have an operating system laying around it wont be so bad but your recovery CD probably wont work with a new board. If you have an old cpu and IDE hard drive you may want to weigh the costs of fixing your puter versus buying a new low-end tower.

If you replaced the psu ( which would be the first thing to check ) then it probably is a bad motherboard. Having the green LED on could still be a bad motherboard, since there is a battery on the motherboard.
In all honestly if its a 3.5yr old emachine, nothing is worth keeping, just upgrade to a new system, but hey keep the hard drives, they're probably the most useful parts. And to keep the cpu ( if thats not the problem ) still not worth it. Just upgrade to a new computer all together.

I'd just go for a new machine - it's nearly at the end of it's useful life anyways (around 4 years for a PC).
As for the parts, you're probably right about it either being the power source or the board itself. I couldn't tell from here which it is - you'd have to switch some parts around to test it.
For the processor, if it's under 1.5GHz (or even 1.8) I'd just not worry about it. And if you did want to try and use it you'd need to find a motherboard that fits it which might be tough at 3.5 years.

Check that the wires from the power switch are still attached to pins on the motherboard. Check for bulging capacitors. They should not bulge or leak.
The processor is probably OK, although you may not be able to buy a motherboard for it outside a museum.
If your motherboard is dead, I'd scrap the computer. Your power supply may be worth saving.

If the machine is having issues recognizing componenets/external things then I would say the board is not happy. Might just be the board and not the processor; but impossible to say w/o getting a replacement.
Look at the cost of a new board & processor vs the cost of a new machine.

well it might be since no fans or any live sign appears. Try to test it with a new power supply first.

You may have a loose screw between your motherboard and case, it could be grounding the motherboard.
