Make sure the PSU switch is set properly 110/115V or 220V which ever applies as well as flipping the switch on the back of the PSU to "1" position if your PSU has one. Also make sure the ATX case power switch is plugged into the right spot on the board. Most new Soyo boards have an LED that lights up when the ATX power supply is attached and voltage is present.

I have purchased 4 MSI Turbo 2 MB's, 4 AMD 1600 XP CPU's, 4 cooler master Fan& HS's, and 4 enhance 300W PS's.

I got one computer completely running with no problem. With the other 3 I can only get the PS to turn on for about 2 seconds.!!!

I have checked the jumpers, all the same. I have checked the PS setting, also the same.

Please help me!!!

This is a basic answer but could help so will post it.

Maybe you have thought of this but in the first case get another known working power supply to try. Also if you have access to a volt meter check the cord to see if 110v is going through it.

In the second case try the known good working power supply on one of the non working computers.

This should at least tell you whether it's the supply.

To Mike Duarte, take the non-functioning boards out of the cases and set them up on a static free mat hook everything up and test outside the case, perhaps you have shorted out something on the motherboard when installing in the case.
