Problem on startup, new computer

[Abula]

I just put together my computer, and everything regarding performance is really good, but i have an issue that i dont know if its normal or not.

Intel Core i7 920
Gigabyte GA-EX58-UD3R
Corsair Dominator 1600 6GB
Noctua NH-U12P SE
EVGA GTX285
Western Digital VelociRaptor 300 GB
Western Digital Caviar Black 1 TB
Antec Twelve Hundred
Antec CP-850
Windows Vista 64-bit

The problem is just at startup, when i push the power the computer starts for maybe a second (all fans light and start including PSU and the Mobo lights up), then all power apparently goes down for about 2 or 3 sec, then all power comes back and everthing from that time on is normal, the voltages of the PSU are well with in tolerance, as matter of fact never seen voltages so close. And the computer is stable from that on, its just on the startup.

Im not sure if this is normal o not, im think its not, but if its not im guessing it could be either PSU or mobo. Maybe there is powersaving stuff that i dont know that might be causing this, im really lost here, maybe someone else have experience somethign similar that can suggest me something.

Thanks in advance for any info or suggestions.

Hm, there are other boards that do something similar...

Is it that the power cuts back, or does it just SOUND like it does? Sometimes if your fan controls are set to manual in the BIOS, they will cut on with the inital boot, then cut back before re-engaging when it gets warmer. This sounds consistent with that behavior.

Check the BIOS and set all of your fan controls to auto...reboot and see if that fixes it.

I've actually got the same "issue". I've also got an i7 and Gigabyte board (ud4p model) but a Corsair PSU. I honestly haven't worried about it. My computer's been stable since I built it (1-2 months ago).

Sorry I couldn't offer any assistance. =/

I'm pretty sure both of you have the same problem. Cut your fans to auto. It will fix it, I bet.

Thx for the suggestions,

I got it fixed by updating bios, even though there is no notes about new bios fixing the cold boot delay/pause, it seems fixed updating from bios F1 to F6.

Yeah, it may have well changed the fan default from manual to auto (which makes WAY more sense, incidentally...why would you have a bios DEFAULT fan speed to manual...that's nuts).

Heh, Gigabyte boards (and others, eg Abit) having been doing this since the P965 Express chipset. BIOS update usually fixes it.
