Computer does not power up at all, have tried a new power supply and still the same, all connections are ok, and it is getting power in to the power supply unit. As the power supply is swiched on via the motherboard ? is there any way of finding out what the problem is on the motherboard ? it gets a bit expensive to try a new motherboard, or do I have to scrap the computer for what could be a simple fix.
I have heard that it is possible to jump start the power supply by shorting out the brown/ green cables on the 20 way connector that plugs into the motherboard ?? this would point the fault to the motherboard signal not getting through ??
I have two computers with the same fault, one belonging to my brother
It is an ATX power supply.
Not possible to switch it on so that I can check the output voltages? without a motherboard ?
Thanks for your time

Much of the information contained herein may have changed since posting.If it doesn't work with the new power supply then the problem is the mother, can you remember when this happen? did you smell burn? Check the Motherboard Capacity, if you see that they look weird than others such as like is kind of Thick then that means that the capaciters are damage and your motherboards needs to be replace.
You can also try to unplug unneccessary devices such as printer, speakers, scanners, NIC PCI, only plug-in to your motherboard the basic component like the keyboard, mouse, monitor, RAM.
