K8N Neo4 Platinum power on/off problem

Hi all.

I just got a K8N Neo4 Platinum, and have a problem with switching it
on and off.

When I switch on the mains to the PC PS(before turning the PC on), the
fans start turning, and I hear disks spinning up. The PC power LED is
off, but the HD LED is on. There is no picture on the monitor.

If I then switch the PC on, it boots normal, power LED is on, and the
HD LED is normal. The PC is working absolutely normal.

But when I power it down again, the fans remain on, power LED off, HD
LED on. And I can't switch the PC on again, till I have toggled the
mains supply.

I have tried measuring what comes on the power connector. It looks
like there is still 12V when the PC is supposed to be switched off.
Don't know if that is right.
There is also 5VSB and PWR OK, but I think they are supposed to be
there.

I hope I have been able to explain the problem in understandable
english

Do you have a USB-Hub with own Powersupply?

 

Yes I do, but is wasn't connected.

When I install a new mainboard, I always start up with only CPU,
memory, videocard, floppy drive, CD-drive and harddisk.

Sorry, if you did that first.

 

I didn't know that site. Thanks for the link.

I tried a search there, but didn't find anything that looked like my
problem. But then again, my german is far from perfect, so I could
have missed something.

Sorry, my first idea reading "Jens" was, he is a german boy.
so try this
http://forum.msi.com.tw/

 

You er right Manfred, Jens could be german. But in my case it's
danish.
I will try to ask the question in the MSI forum, and see if anybody
has a solution. Mut by now I think it's the motherboard.

Good Luck.

Back to MSI with it. When I read the first reviews of the Neo4's I
decided to delay my "must have". I'll wait for the next revision. But my
next board will be MSI. Asus never again!

It was the motherboard. I have verified it with a new board today.
