Put it together and nothing happening - Advice?

Hi everyone, I am in the middle of building my first PC and after carefully assembling the components and making what I believe are the right connections to the motherboard, I don't have any power.

All the components are brand new, so I assume I just screwed up something in the connections. Does anyone have any thoughts as to a rookie mistake that I might have made that would be the problem. My component list is in my signature below. Thanks for any advice!

Antec P160WF case
Antec NeoPower 480 Watt power
AMD Athlon 64 3500+ CPU (Venice)
MSI K8N Neo4/SLI motherboard
OCZ D400 2x1GB PC3200 Ram
Maxtor DiamondMax 10 300 GB Serial ATA

Have you gone thru the mob manual and made sure all of the correct power connections are done properly? All to the connectors seated proberly?

Rugger, thanks for the response. Yes, I feel I've been pretty meticulous about making sure I've followed the motherboard instructions. The only weird discrepancy is that the connections for the front panel with the power and reset buttons are slightly different from what the Antec case manual describes compared to the actual connections I have:

the Power Switch connector on the board is two prongs, with one that has a + sign on it and the other is just colored and I assume negative. The instructions from the case say to connect the Power Switch connector to it, but there doesn't appear to be + or _ on the connector. One wire is blue and one is white. I think I've tried switching them but maybe I didn't.

The Reset Switch instructions say to connect the colored wire to "Pin 1" and the black wire to the ground. In actuality, one wire is colored and the other is white - I assume the white is the ground. On the actual motherboard, the connections I'm instructed to use by the manual are just colored blue. Neither one is listed as a ground. There is also a #9 connector that the motherboard shows not to use that has a + sign. Should I use this connector at all?

This stuff isn't really intuitive to me, so I just followed the instructions according to the manual and unfortunately, that doesn't seem to work.

Have you read hte FAQ in the mobo forum? That has some easy steps to help t/s a system that won't start. It is either the PSU or the mobo. Walk thru those steps and let us know what happens.

Rugger, thanks for the top with using the screwdriver to start the system. That worked, so now I know it's either a defective power button on the case front or somehow my connections to the motherboard were incorrect. I double checked them via the manual, so I'm leaning towards the bad power button as the culprit. Hopefully, I'll get this solved this evening after work. Thanks again for the help.

Got the case at NewEgg, so if I can't get it working by tinkering again with the connections this evening, I'm sending the case back. Thanks again for the help.
