Power On Question

I just put together a gaming rig and I have an odd startup behavior I'm wondering whether its something to worry about.

When I press the power button, all fans and all lights, motherboard, everything, goes full speed for 5 or so seconds. Then, the power seems to cut entirely for another 4 or so seconds. Then power seems to resume and all fans assume their normal default speeds (ie my graphics card fan is running at about a 1/3, case fans and cpu fan similarly) and the system boots as normal.

Since installing yesterday, I haven't had any problems (save having to make a new XP install cd to deal with my original disc's lack of PCI-E support), again just wondering if this has happened to anyone and whether or not to worry about it.

My system is as follows
MSI P35N
Intel 6600 Core 2 Dual
Thermaltake Toughpower 750W
eVGA 8800GT
Zalman CPU cooler (that runs silently, but I have set to full, which still isn't loud at all)
2 hard drives, a few case fans, nothing else out of the ordinary.

My Dell does this. The first time I turned it on I thought "man, this thing is LOUD!".
Then it ran back down to normal.

yeah, it's normal. Generally newer systems have BIOS controlled or software controlled fan speed setting. They default to the highest speed on startup and then when the code loads, they back down to the corrected setting.

It does the same thing on my Gigabyte 965P! So I believe yours is normal.

Same on my two servers, one a Soyo I865PE P4 HT board, the other a Biostar T-7025 AM2 board, and then my two HP laptops (DV6500 and 9550t laptops) and on my moms Dell Vostro 1500. They all start up hard, then simmer down.

Gigabyte 965P here too, and while it doesn't always do the "power-on for a second, power down then back up", it always starts the fans at full speed, then lowers them once it has the temp readings in and manages fan speed.
