Pc randomly turns on

[bigdaddy64]

Ive built my pc about 2 weeks ago and 2 days ago when i turned it off it turned on after about an hour, on its own. Yesterday it did the same and i turned it off again and now its been turned off all night. Also when i turn it off the process takes about 10 seconds, why is that?

Yea, enter BIOS and disable all Power Management.
And set "AC Power Loss State = Stay Off"

Overall, when you turn off your PC, you should turn off its main power as well after it actually powers off. Never force the PC off after it's first turning on, it will be loading the OS during that time. So during a PC power on, either enter the BIOS and then power it off, or let it fully load up into the OS and shut that down properly. Don't force power off during OS loading.

Which Motherboard is this?

List your full specs and OS please.

But yea disable anything power, standby, wake-on-lan; etc.

Overall, none of this really matters if you just turn off the PSU when you're done using your PC, simple as that.

Most boards by default should have all these options set to off until the user manually adjust them to prevent this kinda unwanted scenarios. Never hurt to double-check though.

Disable Wake-on-LAN in BIOS. Otherwise certain network activity may turn it on.

I meant turn off the main PSU switch after a system shutdown + power off.
To ensure it can't turn back on, period. The main PSU switch is just stand-by power.
