Need Help on Booting up New Computer

[chopp]

I have gone through great trouble for helping my friend building his new computer. Ive gone through the hassle of changing wiring, getting new parts, and visisted various websites, but I am still having trouble building my friend's new computer. The problem is after putting together all the parts, we turn on the computer and nothing shows up on the monitor, and I dont hear the beep noise that computer is suppose to make when you turn it in. I suspect the problem could have to do something with bios loading from the motherboard. I would greatly appreciate some advice to fix this problem, so I am able to boot up the computer and access the bios. Any advice or help would be great thanks.

Make sure that the jumper for the clr cmos is set to 1-2, not to 2-3.
If that is not the prob, have you reset the BIOS by taking out the CMOS battery whilst the computer is unplugged?
Do you get fans spinning and LED's switching on?
What are your system specs?
What pwer supply?
What cpu/mobo/case etc?

Have you connected the mobo speaker properly?
Have you taken out everything and replugged it?

What happens when you unplug everything from the mob except power, cpu+fan, mobo speakers?
Add a vid card, what happens?
