Darn thing won't shut off.

[Callas]

This is my first experience with an ATX, so maybe I don't understand how they work. I have an expensive Enlight case that I've put an FIC motherboard in. All new stuff. It won't boot up to the BIOS, and the power switch won't turn off the power. I have to unplug it, however, when I plug it back in, the power has been reset to off. QUESTION: Do I have some kind of remote relay that's not working properly or is the problem with the mobo? Your advise would be appreciated.

ATX is designed to support wake on LAN and other quick power up functions that leave some power on at all times. That is why you must unplug it to kill all the power inside.

As for the rest of your situation, I don't have enough experience yet, but am sure someone else will respond!

Thats a typical occurance for an overclocker! ATX power on and off is controled in software from the MB and from the power switch connected from the MB to the front panel. There is no direct connection from the power switch to the power supply.

If this is a result of a system change such as fsb/multiplier/cpu setting you will have to reset the cmos by temporarily placing the ccmos jumper in the clear cmos position then putting it in its normal position.Then you can change sys parameters to those that will work.

Software problems can also cause a PC not to shut down, but usually the OS is up first.

It is the design of the power supply type and sometimes this happens!

Try just holding the power button in for a couple of secs.

Boards with the award bios sometimes use a 4 second powerdown. This means you need to hold the power switch down 4 seconds to make the system poweroff. The system should poweroff after you select shutdown from windows

as for not booting to the BIOS, What do you see when you power up?? Do the drives spin?? do the case and CPU fans run??

So once you get to, "Safe to shut down" or something like that it does not turn off? Press power for 5 seconds, if that is no go, the power buttin is set for wake/suspend, set it to on/off in bios. I hate ATX.

While were on this subject. When the power goes out. An ATX computer will stay off when the power comes back. Is there anyway to have it power back up like an AT computer?

[Hurt_Me_Not]

Yes their's an option under bios as to what you want the comp to do when power returns.
ie Stay off,Turn on,As last state etc

Hey... thanks for all the help. I'm sure you've provided me with the answers to the shutdown mystery. I intend to try your suggestions just as soon as I can get the motherboard to boot to the BIOS. At this point, I've got it beeping when I take the memory out, but it still won't boot with it in.

Funny, I read in my manual that holding the power switch in for 4 seconds will kill the PS but it just didn't seem to cooperate!

This usually only happens to me when I try a overclock combo that don't work.

I really am talking about the "won't boot up to bios part" when I said the Clear cmos thing will work.

I did usually hit the manual on off rocker switch on my power supply to kill it if it wont shutdown automatically tho.

I'm glad that the holding of the button worked for you but if it ever doesn't, just remember you can do the CCMOS thing!

Thanks to everybody that chimed in, I'm up and running now. Even upgraded the BIOS. As for the delay in shutoff, It's okay for now. If I decide that I want it to shut off instantly, I'll check the other tips I was given.
In gratitude, I'd like everyone to take what they want from my freesite = http://nexad.com/freestuff.html ... Thanks again gang ... enjoy!

You may want to check your motherboard manual to see if it has a permanent on/off jumper in addition to the momentary on/off jumper... All you have to do is move the power switch over to the permanent pins, and then when you push it, it cuts off with no whining or arguments, and no dopey 5-second wait. http://www.sysopt.com/forum/smile.gif
