Breadboarding

Do you have a case speaker attached to the motherboard? if those components are all you are using then no you wont be able to hear bios beeps.

a case speaker and speakers are very different. Real speakers require alot more power than the case speaker as a case speaker is really just a piezo buzzer. You can get one here

I don't think mine has a case speaker. There is a bunch of lines for the front panel leds and switches, but there is no line for the speaker.
I'll try Fry's tomorrow to see if they carry case speakers.

I agree here mostly, the only thing you cannot tell, and this is a big one as a lot of people cannot seem to get a board installed correctly into a case, is if the board is shorting to the case somewhere. Happens a lot with first time builders. In all the PC's I have built, I only had one board years ago that I had to take out of the case and actually breadboard, and after hours and hours of trying everything under the sun even while it was out of the case, it suddenly beeped and POSTED out of the blue. Reinstalled it and everything was fine. Never did figure out why it wouldn't boot at first.
Anyway, yeah a lot of people put boards in without standoffs. The only way we can really help them from here is to find out for sure if they have the board mounted correctly, and that means taking it out of the case, and breadboarding it to start the troubleshooting.

A word of advice to all new builders.....Order a motherboard speaker when you buy your new motherboard. Most boards do not come with them anymore, (at least my last couple of boards did not) and neither do cases. They only cost a couple of bucks, and if you have a problem that is the first thing you need!
