The computer turns itself on about once every 12 hours. What to do?

Question

Iron

For more than two years now I have had a desktop (PSU 500W, C2D8400 3.0GHz, 4 Gb, Radeon 4870 512 Mb, W7U), connected through a surge protector, for the most part it works properly and does not cause any trouble. Yes, I must say that I almost never turn it off, but only put it to sleep, after which you can return it to consciousness, in theory, only with a button on the panel.
And from this place strange things begin: all my life the computer is turned on not only by this button, but also by pressing any button either on the keyboard or on the mouse, which, in theory, should not be done. But I'm already used to it - it's convenient. I am not surprised by his manner of waking up even when taking out some USB device (for example, a flash drive), although this is even stranger. I also got used to this, not fatally, and I understand that even a weak electrical impulse, in principle, is capable of awakening the system. And so, about one and a half to two weeks ago, this infection began to turn on regularly without demand. Herself. You sit like that, read a book, and then - wshshshshsh! - rustled, dear, already showing the wellcome screen. And it's okay if during the day, but after all, at night, it happens, it cuts. Such a habit of turning on at all without any intervention from someone's side puts me in complete bewilderment. What the hell is this autonomy? Mysticism is also added by the fact that it turns on - attention! - every day strictly between 2 and 4 o'clock in the afternoon, and sometimes between 2 and 4 o'clock at night. Most likely a coincidence, but it's uncomfortable ...
So here, actually, questions:
- What unknown forces force it to do it?
- How to stop it?
How can I make sure this shit doesn't happen again?
“Where can I buy protection against the uprising of machines?”

Answer 1

Feed.

Answer 2

Go into BIOS Setup and disable in the Power Management section (or something like that) all unnecessary wake-up events ...

Answer 3

And in the task scheduler nothing is indicated for this time? for example, installing updates with the right to turn on the computer for such an action

Answer 4

I had this when the electricity in the house began to jump actively. There was a jump, and the computer started up by itself. I fixed it simply - first I turned it off for the night / time of absence, then I bought a filter and UPS.
PS. Sometimes it turned on from a power surge not noticeable even by the lamps in the chandelier.

Answer 5

Wake on lan disable.

Answer 7

And from this place strange things begin: all my life the computer is turned on not only by this button, but also by pressing any button either on the keyboard or on the mouse, which, in theory, should not be done.

Oh, I remember such a problem, I myself suffered. The solution is simple: Go to the control panel, device manager, find the mouse, keyboard in the equipment and uncheck the box "Allow this device to wake the computer from standby / hibernation" in the properties.

Answer 8

perhaps automatic defragmentation is still running ... by default, it usually starts just around 3 o'clock in the morning. at the expense of the rest, as advised above - you need to dig deeper into the BIOS with the power settings.

Answer 9

About six years ago, my computer also turned on by itself. It turned out that Wake-on-Call was enabled in the BIOS, and the computer woke up on any phone call thanks to the Dial-up modem.

Answer 10

Have you tried resetting the BIOS? Well, that is, pull out the power and remove the battery for a couple of minutes to be sure. With the default settings, this should not be the case.

Answer 11

Can.
Read the event log.
Roll the update, rearrange the Windows, check the memory.

Answer 12

I also recommend looking into the system logs - maybe there is something there.

Answer 13

If everything is in order in the BIOS, then an obvious iron glitch. We change everything little by little or all at once in a crowd :)

Where can I buy anti-machine uprising protection?

SkyNet in St. Petersburg is already working.
So it's too late to drink Brojomi ...

Answer 14
