I have got a computer from a friend, and its not working. He said that one day he woke up and the computer didn't turn on. I went in the computer, and checked inside for any bad connections, but everything seemed fine. I thought it was the PSU because he said before it became completely dead, it turn on and then suddenly turned off. I disconnected all the cables from the motherboard to test the PSU. It didn't turn on. I found online that if you use a paperclip to connect the green wire's connector of the 24 pin connector to one of black wire's connectors, you can turn on your power supply without having it connected to the motherboard, and it will turn on when I do this. But when I actually have it hooked up to the motherboard, the power supply wont turn on. Would this be an issue with my motherboard, or do I probably just have something hooked up incorrectly? Also when i disconnected the cables I also disconnected the Power LED and Power SW out. I do not remember exactly how they go, so it might be that the problem. I have try to put them in different ways, but it still doesn't work.
Type of Computer and Info:
- Emachines Model: W3653
- New PSU (Passed the paper clip test)
Then I'd say it's a dead motherboard. See if this is the board http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail...
You can download the manual and properly connect the power and reset switches. Try connecting the ATX power cable, shorting the 2 wires and then turning on the power supply. See if the board starts this way.
Alexoiu: Thank you I got the cables connected correcly, but I do not understand what you mean with (Try connecting the ATX power cable, shorting the 2 wires and then turning on the power supply. See if the board starts this way.)
Rolli59- Alright, Well I did try another PSU, and it didn't work, but then I put the PSU from the computer that wasn't working to a working computer, and it turned on fine.
I meant to turn the power supply on having the green and the black wires connected together (force the power supply to start when connected to the board). But if there's a short there are chances to damage the power supply. So better not trying it.
- The Second System is Newer
- I removed all the cables except the basic ones to test, but the motherboard doesn't beep or anything. The Fans don't spin, and even though the PSU works, when I connected to the motherboard it doesn't turn on.
