problems booting the first time

[subgenius]

I've installed all the hardware according to the manuals, which weren't the best references to begin with, and then I went to boot up for the first time. When I booted, the fans turn on, I got a green light on the motherboard, and the LEDs turn on, but after about 3-5 seconds, the computer just shuts off (no beeps, and didb't even make it to BIOS setup).

My theories:
1. 4-pin power supply not connected, but I can't find where it should go
2. My surge protector not powerful enough to handle 380W ps
3. Heatsink not connected properly
4. No bootup CD in drive. I couldn't find out if I'm supposed to put either the motherboard support CD, or WinXp install CD in the drive when I try booing up for the first time, so I left it empty.

Here's what I got under the hood:
ASUS N7V8X deluxe
AMD Barton 2500+ & heatsink
Sonota Case w/ TruePower 380 PS
1GB Crucial RAM PC2700
Matrox G550 video card
Pyro DV Capture Card
LinkSys 10/100 card
52x LiteOn CD-RW
16x LiteOn DVD-ROM
160 GB Maxtor Ultra ATA HD

Thanks in advance for any help

Hmm...perhaps something goofy with your power switch?--like you're turning the machine on, but holding in the button so it shuts down after 4sec. I suppose it could be thermal protection and the board saving your CPU. It wouldn't hurt to reseat the HSF.

Check to make sure the motherboard isn't shorting itself by having part of it hitting a drive cage or something.

k, first check # 2 by skipping the surge protector. #4 shouldn't matter b/c the computer wouldn't shut itself off just cuz there's no disk. (use xp first- the mobo cd prob has some utilties for temperature monitoring, overclocking or out of date VIA drivers (if this board uses via chipset))

I'd then rip everything out again and start over, this time using only floppy w/dos boot disk, graphix, 1 stick of ram, mobo, ps, and cpu. Like knightlife said, check to make sure don't have anything metal touching the sides or bottom of mobo. if it works, then add one item in at a time (harddrive, capture,cd,dvd,sound,network)

make sure you have got some grease or at least a heat pad on the bottom of the heatsink/fan, too. (you got case fans in there, too, no?)

Also, just cuz I'm that sorta fellow, I would rather have more wattage w/ all the stuff u got in that case

Sounds like the HSF is not connected to the correct header or the mobo is shorted to the case.
