    Thanks for responding. It doesn't even POST. I am very new to this. I thought it may have been a simple fix. Like the power button. Do you have any recommendations of where to buy another motherboard? I also would like to know where I could find some kind of spec sheet, on the motherboard. I am not to fond of this motherboard anyway. I would like to find one similar, or that would fit, that doesn't have the on built in video card. As the one in it doesn't have the power to run most my games.

    thanks again for you response. The power supply isn't even coming on, no fan, nothing. I will go out today and try to find another power supply to fit. I think I'll get a little bigger watt. All the research I have done says that this eMachine's, at least my model, the power supplys had to low of wattage, that was a major factor of burning the motherboards out. But first I'll try a new power supply. My motherboard mearures 9 1/2 X 9 1/2. I think the motherboard for the Asus A7V8X was 12 X 9.6

    Replaced power supply, still nothing, no light, no fan, no noise. I guess its time for a new motherboard?

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.

    Remember that if you here the post with RAM and CPU and Keyboard, remember that you can't see anything if you don't have a video card. SO, the first part is to HEAR a post, the next is to SEE a POST and boot process. 'Cause the video card could be bad.

    Remember that the cards and components being pulled out can help to reseat all things so the contacts are re-established.

    Always remember to take the necessary precautions with the static electricity and sensitivity with the components. If you aren't comfortable with this, then have a service center evaluate it for you.

    Is the powersupply even coming on? Can you hear the fan in the back, "do the wheels turn". If not, replace the power supply first. It's a 250 Watt and you'll have to find one the measures correctly in your case.

    Spec Sheet can be obtained following this link. The motherboard replacement can be ordered at the same site.

    Here is a recommendation for a new motherboard.

    Asus A7V8X, you can find one on ebay. It might come with other components too, but Asus is a good buy. I think your case requires a Micro ATX, so you need to make sure the size of the MB is the right size for the case. Or pick from this list of your choices.

    The type of motherboard you're looking for is an A 462 Pin AMD Athlon 333FSB. This is to be able to use the current components in the system. If you want to redo the components, you should bypass the upgraded and buy a new computer that has the specs you want to play the games.

    You might be able to use the remaining components in the computer, but remember that some might be bad. This might still be the reason why the computer doesn't post. Just a reminder.

    If I have FixedYa, please rate accordingly, thanks.

    Yes. The power supply should be coming on with some kind of power draw when things are functioning. A larger wattage will help, yes. I think there are always good sales on EBay or NewEgg.com. I like their stuff.

Green turn on button will not come on just orange lite. green button don't turn on at all nor will computer boot up. model T2865 bought in 2007


Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((motherboard to your hard drive))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error hope this helps

Computer will not turn on


Best way to check is to open your case. Near the power supply plug to the motherboard should be a little led light. If it is getting power to the board this light should be green. If it's unlit then most likely your power supply has gone bad. Hope this helps.

NEED TO KNOW WIRING


i have been to fic's web site, i cannot find any mb labeled au31.

do you have anymore information about the board, how old, which processor, what socket, which north bridge, south bridge, which model system, etc?

 

however the pins are usually marked "pwr sw" or "pwr" and are usually with all the other front panel connector pins.

Unit will not turn on


Our experience with that model has been defective motherboards. You can replace the board with a generic board if you cannot find the emachine board. You might have to reload Windows if you do.
