motherboard power light on, nothing else starts. Sabertooth x58 motherboard


Hello,
I have a sabertooth x58 motherboard, and a Cool Master II Advanced case. When I plug in my computer, the light on the motherboard to indicate that it is receiving power is on. However, when I try to boot it, nothing else turns on, not even the fans. I have all of the connections tight and secure. However, there is 1 wire which I have not yet plugged in. It is part of a bundle that comes from the top of the case, where the power button, restart button, usb ports, and esata ports are. Because of this, I fear that the wire is coming from the power button. However, there does not seem to be any place to plug this in. Any help on this matter would be greatly appreciated. Thank you in advance for your help.

Look at page 2-36 of the manual. There is a 20 pin header that connects the power LED, power switch, speaker, HDD activity LED and reset button. The power switch is probably a 2 wire plug. If not marked you will need to trace the wires and verify where they go.

If you are comfortable enough you could also remove the RAM/memory from the DIMM's (remove all the memory). If the board isn't toast you should receive some beeps which indicate board errors. For example: missing video card, missing RAM/memory (this would be you if you removed the RAM/memory), no processor, etc. You can check this site for generic codes: ComputerHope.com.

Good luck, I hope the board is ok! If you do remove the RAM/memory and it beeps at you, there is a good chance one of your RAM/memory modules is toast. Try one RAM/memory module at a time.

Furthermore, if all of the wiring checks good disconnect any peripheral i.e. disk drives etc. If still nothing then remove any PCI cards. If still nothing and removing RAM does not help try reseating the CPU.

I always try 'jumping' the power switch before pulling parts. By 'jumping' I mean 'starting without the switch'. All the switch does is connect the 2 pins that the switch is hooked up to, if you connect those 2 pins with a conductive tool (eg a screwdriver) the system should start.

Its amazing how often a dodgy power switch and/or wiring can stop the 'start please' signal getting through.
