I have built pcs in the past, no issues. For some odd reason, I now am having a bit of an issue with a new build.

Have an Epox socket939 board, athlon 64 cpu, new Antec 380 power supply. OS is Win XP MCE. Installed fine, runs fine. Boots without issue.

Windows shuts off. The motherboard and powersupply do not, unless I hit the switch at the back of the PC. having to do that all the time is a PITA.

the motherboard people told me to check connections, etc etc. checked them all. bios is the latest and greatest, the connections are all exactly as they should be according to the manuals. I can restart the PC no problem. but if I shutdown from windows or from the power button, the screen goes black and windows is off, but the motherboard and psu are still on. and then no power button or reset on the front works at all.

I have tried almost everything I can think of, and right now I am beginning to suspect a bad board.....any ideas??

thanks

Maybe you could disable power management in the bios to see if it helps? Did you by the way install any drivers recently?

well, it hasn't powered down since it was built---i set it up last weekend, fresh install, fresh drives, and adding things piece by piece. with a bare pc or not, it has been doing it all along.

the only recent drivers came yesterday with new nvidia drivers for my geforce5200. which is flickering when i click certain icons, but thats minor to me now

i brought home my older athlon xp motherboard and cpu, just to rule out RAM and OS among other things. really suspecting the motherboard at this point

Unless it's something simple like a reversed power LED connector, I'd be suspecting the motherboard too.


Or perhaps a faulty power switch in the case?

i triple checked the connectors. they all worked on the old board/cpu/psu combo. using windows xp or power button to turn off all worked.

im about to shut down and check to see if the old board still works. if so, ill be doing a replacement with epox.

i once had this happend with a older computer repaired i reloaded and it was the keyboard .!
i would check the front panel connection to the board .

definetly not the front connections. unless they are bad on the board itself. I have connected, reconnected and checked them at least 3 or 4 times today alone, plus another several last night. nothing works. it runs fine, powers up fine, resets fine. just doesnt want to shut down at all.

i know the connectors are fine cabling wise. they worked perfectly fine on my old shuttle mainboard up until i retired it last week.

i pulled all extra cards and drives, and alternately pulled my DIMMs. nothing. unless I completely missed something, the culprit is definetly the motherboard itself, something I decided on earlier because the onboard diagnostic LED, when I tell it to shut down, displays code FF when the board/fans/PSU remain on. FF in the manual indicates a couple of issues possibly, and the only one I have left is a mainboard problem.

so, as annoying as it is, Ill end up somehow returning this/replacing. but i may opt for a different board now, so I can have the system running without missing a beat.

It's a quite recent board, and perhaps this is a matter which might be resolved with a BIOS update, but apart from that I'm in agreement with you.

I have updated/reverted to the newest bios and what it came with. Nada. It's the biggest problem with the board, but not the only one. Had some good reviews, but maybe I was just unlucky. Time to hunt for a new one, me thinks

thanks for all the help, and I'll let you know how I make out

I was meaning that it may be a problem which, wuth your paticular configuration if hardware equipment, will need to be resolved with a future BIOS update. Such things do happen.
