Problems - ASUS A7V

[hiltunna]

I believe that what I'm seeing here is a defective motherboard, but who knows, it wouldn't be the first time I'd been wrong.
Here's the deal: building new computer for little brother, who's off to college. Using an ASUS A7V and TBird 1 GHz. Put the entire system together, excluding expansion cards besides the video, and plugged the power cable in the back. When I flipped the toggle on the power supply, the computer booted by itself, without me so much as looking at the actual power switch. I turned it off, thinking there was a serious problem here. I started eliminating variables (shorts, connections to power switches, connections to drives, connections to switches and LEDs, etc.) until I was left with a motherboard, a processor and a cooling fan. It still boots itself when the power supply switch is on.
Is this a problem with the board's internal ATX logic switch for soft on? Am I retarded? Should I throw the box out the window? Perhaps slice my wrists with the generic pc-133 RAM I purchased?
If you've got any real suggestions, i would be so glad to hear 'em.

Check the BIOS and see if power on is left to LAST STATE or similar. This causes the mobo to power on when U power on via the Powersupply.

I too just built a TBird/A7V system.

Does it actually try to boot up or does the fans and internal light come on?

This MB is kinda wierd, it seems to try to boot but is really in more or less in a wait state.

You have to push the power switch to actually boot up. When you shut it down, if you hold the power switch down for less than 4 seconds it goes into hybernate mode, but not off.

This MB must retain some type of charge for a short while as well. If you look between the AGP and 1st PCI slot, there is a green LCD. If you pull the power cord off the machine, the LCD remains lit for a 4 or 5 seconds.

Guess I'm rambling, but make sure that the motherboard is just "warming up" instead of booting up. When you plug in the power, the fans will start spinning up but will shut down in about 2 or 3 seconds. (Unless my MB is wierd too!!!)

its not weird, its a cmos setting that makes it more convenient in case you turn your computer on with a power strip, that way you don't have to hit the button. The other setting allows you to turn it on with the case switch. I'm at work and can't look to see exactly what each is named, but it's fairly simple, though slightly alarming at first boot when it powers on then off.

The Asus with power up for about 2-3 seconds for a self test if you unplug it and plug it back in, that is quite normal and some other boards do it too like a few MSI boards.
