Hi guys,

I've noticed something this past week with my newly built PC and can't seem to figure out why it's happening. I'll use my PC, shut it down and it will power itself off. However after like 12hours maybe longer the pc will just switch itself on again.

At first I thought it was maybe one of the kids, accidently hitting power switch when dusting or something like that. However it's been shut down since Sunday night and no one has been near it till this morning and it was on. It wasn't on yesterday morning before I went to work. But sometime between yesterday morning and this morning it has come back on.
 
very strange, never heard of that.

is there any options in the bios to have wake on LAN enabled at all? try turning this off if its enabled.

not sure if this what could be causing it but might be worth a try
 
I was laughing and joking about it when it first happened saying I had bought a Knight Rider style PC because I says on the phone on my way home when I get in I'll be going on the PC and when I walked into the room it was booting up.

I was thinking about the lines of maybe it's not actually shutting down but going into Hibernation? But I am using the shut down option from the windows 8 menu so I see no reason for it to go into hibernation instead of shutting down.

I'll have a look through the BIO's I'm using the MSI Z97I board so it maybe something linked through the killer LAN settings?

check the bios for any LAN options, they should have some in there and maybe disable the wake on lan one (if its there and enabled)

normally PC's turn themselves off and not on unless you wanted it too lol

It's probably powering on via USB. My media PC does this if I touch the mouse by accident.

Only have my Razor Blackwidow Ultimate and Cyborg R.A.T 7 mouse connected via the back USB ports. The mouse is connected to the normal USB slot on the back of the board and the keyboard requires 2x connections and is connected to one that's labelled SS USB but have no idea what that is.

No one has been in the room to touch mouse of keyboard, or would they not need to be touched?

SS USB is the USB 3.0 ports, they will have a little blue bit in the USB slot on the PC rather than black which is 2.0
 
i had a problem like that, an old rig would power up during the night and spin all the fans, try a boot and shut back down, turned out to be a short on the PSU
 
Had this only last week on a Z87 sniper, disabled the options in device manager like magic packet etc hasn't done it since
