Having problems with your HP Media Center M370N (DM163A#ABA) PC Desktop ?

Won't turn on with new power supply

\015 My computer mysteriously wouldn't come on one day so I replaced the power supply in hopes that it'd fix the problem but it didn't. There is a green light that turns on on the motherboard when the power cord is plugged into the power supply, but the computer still won't turn on. Can anyone help?\015

Answers :

Well there are two types of Power supplys.
One is a 20 pin and the other is a 24 pin.
If it is a fairly new computer, it will be the 24 pin model.
Look carefully at the plugs that connect to the motherboard.
There should be a 4-pin connector with two yellow and two black wires. That is the 12 volt connector that supplies power to the CPU.
Make sure it is plugged in behind the CPU and seated all the way down.
I have seen this happen before - you will plug in the drives and the main connector, but forget the CPU connection.
Sounds like the switch is out to me or it is mis connected to the motherboard
