i have a gigabyte p35-ds3r mobo
the default setting has pme on wake-up enabled
if i enable this everytime i shut down my computer it would just turn itself back on
i have to disable this

can someone explain why this turns on my computer?
it's hooked up to a router thru ethernet cable

disable wake on pattern match in the network card's settings (from device manager), also in the device manager-powermanagement, put a check mark in "only allow magic packet to wake this computer".

i can disable it
i want to know wut triggered the pc to turn on right after i shut down

Any activity over the network to the PC will cause it to immediately turn back on if you don't tick the "only allow magic packets" option.

Hey man, you didn't even answer his question correctly.
He wants to know the exact packets that triggered his PC to turn on.

so lets say i bought this computer brand new , with everything in default setting
after loading my windows, i won't be able to turn my computer off cause "only allow magic packets" is disabled?

no idea;

wake on lan turns your computer back on when certain events happen on the lan, the options i recommend above do not disable the feature, but they narrow down the scope of what will trigger a wake event. You are not likely to accidentally receive a magic "wake" packet.

and if your asking are computers mis-configured, or configured in strange ways when they come from the store? uhhh yeah, all the time... you wouldn't believe it

i see
it's just surprising that a new computer woudln't operate properly without tweaking first

There are very few standards with generic PC components. Each manufacturer when implementing their product may have an implementation that differs from the reference. It's just the nature of the hardware. I've had plenty of components that had weird quirks like this.

like fresh out of the box?
