Motherboard power on without switch
After a problem with my old system, I upgraded but am stumped with this problem
Got the Motherboard on the bench, it's a Gigabyte GA-MA770-UD3
Using an AMD PHENOM X4 QUAD-CORE 9650 2300MHZ 4MB 95W AM2
With GeForce 9600GT, 1GB, HDCP, HDTV, PALIT Graphics card
And 1 stick of 2GB Crsair Memory
Powers up as soon as I switch on PSU without the power switch involved
Now, Iv'e tried everything I can think of -
Different PSU
Different Proccessor
Different Memory, Different memory bay
Different Graphics Card
No power switch connected
Have made sure nothings shorting out and the board looks physically fine, but I'm sure I came across this problem years ago on another build.
Any Ideas ?
Thanks,
Stephen

I've got a Dell that does that the first time I boot after the power supply is unplugged and reconnected.
It works normally after that, until I unplug it again.Hard Sayin Not Knowin

Look in the BIOS for the settings "What to do in the event of a power failure." Set it to do nothing.
Also look for wake on lan and make sure it's disabled.Imagine a world where dogs took bad owners to the pound...

Wish I could get to the bios to change something - the board powers immediately, without manipulation of the Power Switch pins - so there MUST be a short circuit somewhere on the board and this does not allow a video signal to get to the monitor

You should rather have 2 sticks of 2x1GB memory, as dual channel (having two sticks of RAM in the correct slots) work a lot faster. You should purchase another 2GB stick if you want to get the best performance. Also consider installing 64-bit, Phenoms support it and 64-bit gives you much memory advantage.
