power and no boot

Sup ya'll it's been awhile, but another hardware prob,computer wont boot, it's a emachine model 2646, and it has a power button on the front, asa soon as i connect the power cord to the back the power button lights up but i get no power it seems anywhere else, no fans or power supply fans nothing? hmmm confused and it's a customers lol, tryed a diffrent power supply and got the same, i get nothing on the screen at all and it's onboard video, all i can guess is onboard video gone?? going to look to see if i have a spare card around for testing while i wait for post thanks ya'll

If the fans on the board arent running....then its probably the board

seeing you swapped the power supply already

Ensure that you have the power supply properly connected to the board

yeah i plugged another supply with the same results but it's strange shouldnt i get beeps of some kind for the board to go bad and thatnks for the quick reply

No...its the board that beeps at you telling you no video, no keyboard etc....

If the board is fried...it cant beep...

If the fans dont run..it is not getting\handling the power supply properly.

cool man going to go with board prob then, thanks alot

Well...it could also be the power switch.....not connecting and initiating the power supply....may want to check that out before trashing the whole thing

Sorry..not familiar with the hardware..dell??

the board is not getting power for some reason....

Howdy.

?Maybe the new power supply has killed the board when the power cord was connected. Was there like a spark noise when you connected the power cord?
A wierd smell coming from the board?

cheers

I agree with Morgana~

It is either the switch or the board, but I don't know that hardware either.

Take a look at the switch, you may have to "hot wire" it. Also look to see if the switch has a small glass fuse in its circuit to the MoBo...................OK I haven't seen one of those in ages, but it is just possible?

You say that the power button lights up? that tells you that power must be reaching the switch, if I understand you correctly.

if the power sw light is coming on, then it implies that the sw is OK
as the wiring would be such that the light is connected AFTER the switch
otherwise the power light would be on as long as a power cord was plugged in :eek:

I am inclined towards Morgan, and would ask / suggest that if you have access to another PC or Mo/Bo that you play part swap to find what, exactly, is not playing fair ........

Hey Foxy~ I see what you are saying mate, but I have seen them where the I/O switch button lights up, but you don't get power to the box until you actually trip it............sort of like an "all in one" standby indicator?

If the switch is faulty in that situation, you would get the symptoms described.

Someone else is having the same problem as you over here:

Emachines noturiously have bad power supplies - however it sounds like a MoBo fault in this case.
Not sure if you have an ATX MoBo but if you do they usually have a little LED on them that tells you if it is receiving power (there should always be 5v circulating on an ATX MoBo when power is connected to it.)
You could have a look for this - but like has been said - if you have changed to power supply it will either be the power switch or the MoBo - my money is on the MoBo - however have a quick check towards the bottom right corner of the MoBo to double check you have not pulled the power connector for the switch when you replaced the Power Supply.

Good Luck!
