Newly built computer - no power

I just finished putting together my first computer. When I went to power it up, it just sat there. NOTHING is running, including the power supply fan. Is this a bad power supply or a wiring problem? Is there a way I can check the power supply without using the power switch on the front of the machine? This case also has a power toggle on the back of the case.

By the way, it's an ATX with an Athlon XP 1700+.

probably a wiring problem if case and PS are new. Disconnect everything from mother board including ram. leave only the processor connected and case switch wiring. double check your switch connectors. you could have the front power switch on the wrong pins. If you are shure about the switches, then do what I said and power it up just long enough to see any action (fan,beep etc)then shut it down. next plug in your ram, power it back up, then do the floppy drive and so on. Remember, usually it is a loose connector, backwards connector or connected to the wrong spot.
Also did you check for any jumper configurations for your board? Wierd things can happen when jumpers are set wrong. Good luck

Is it possible that the connector is on the right pins but is on backwards?

]Is it possible that the connector is on the right pins but is on backwards? I suppose it is possible but i don't believe it really matters since the switch is just shorting the pins to activate the circuit. The link that was posted in the previous message is very good. Check it out.

Sound like the exact same thing I dealt with on a computer I put together. Turned out that the motherboard CMOS jumper has to be moved to the other position, then power it up.

Make sure your selector switch on the back of the power supply is set to 110 and not 220.
