Hi,

my pc turns on in middle of the night for no reason if I forget to turn of the psu. And yes I turned off network port function to turn on the pc. So what can it be? Bad PSU, motherboard, crapy case power on button? I have chieftec PSU, asrock 790gx motherboard and coolermaster elite 370 mid tower chassis. Also sometimes when I turn on PSU back on, pc turns on, dont even press power on button on the chassis.

What do you mean by the "network port function"? Try going into the power options within the BIOS and disable "Wake On LAN".

Either you have ghosts or something is not working right. Over the years I've ran into these problems with my computers waking up. Fixes for me have been the "Wake On Lan", Bad Motherboards or Mobo Power Settings, Bad PSU, Bad Case Buttons or Short. While in sleep mode I've had more issues of waking up with things such as Windows updates, Bad Mice, Shared Printers ect..

Best place to start looking is Windows 7: Lastwake Command

In the command prompt, copy and paste the command below and press enter

powercfg lastwake

Its says wake history count - 0, does that mean I have to check it when it wakes and not in morning when I start it myself?

That's not telling me much, perhaps try that command again when you find it awake.

Also disable "Wake on Magic Packet" and "Wake on Pattern match".

And in Power Options-->Advanced Power Options-->Sleep. Set "Allow Wake Timers" to Disable.

Well I bought better brand PSU and it didn't turn it self on for a week now. So if someone has the same problem PSU might be to blame.

A bad PSU most assuredly falls into the realm of mysterious power-ups. Just keep the old PSU as a backup. I'm glad you found a fix.

I would suggest we check if we was just putting the computer to standby mode but not shut down during the night. So any single movement on the keyboard or mouse or network unstable electricity current may trigger the computer to power on again. I have seen some mouse pad with uneven surface triggers the PC to work again from standby mode.

Try install the latest mobo chipset driver and must reboot the computer once after the latest chipset driver installation.
The latest chipset can help to maintain a better system integrity.

Hope this helps.
