Problem with ATX Power switch !!

[Gia]

Yesterday I have tried to build my PC for the first time...I think my case has strange LED connectors!! I don't have any Power Switch !! I got these 4 little connectors from my case :
- POWER LED(3 pins but there is no space in the middle!), black and green

- RESET LED 2 pins connector, grey and red

- HDD LED (IDE Device Activity Led I suppose), black and red

- The last one has no name on it and it's just 2 separate pins white and blue !! I think THAT is my Power Switch connector because it's rely to the Power switch but I'm not sure...
My mob is an Asus P2B

Also I discoverd that a pin lack in my floppy connector... Is the system can power on anyway ?

Well Thanx a lot...

The power switch connector is the one that connects to the power button on the case

Your computer can boot without a floppy. Just change the bios to boot first from your harddrive. If the connector is connected to the actual switch, then it is your power switch. Try putting the connectors on backwards also.
