Turn off the computer via start. Is shut down, but then it is included. Rearranged Windows on the other, nothing helped. What could be the problem?

Try the following suggestions, maybe something will help:
1. In the settings BIOS and there are options that can "contribute to" samovyrajeniyu computer: Power on Alarm, Wake Alarm, Power by Mouse, by Keyboard, Power, Modem Ring Resume, Wake on Lan, Power on After Fail Wake Up by PCI Card, PCIPME Power Up control USB Port Wake Up PME Event Wake Up, and similar parameters. They should all be in the "Disabled" state. May be slightly different names depending on the version and BIOS. Depending on the version BIOS and these settings can be placed on such tabs as "Power Management Setup", "Power Management Event", "Integrated Peripherals".
2. As already mentioned here in the answers, try to reset the BIOS removing the battery and just in case, replacing it with a new one.
3. To disconnect the Internet cable from the network card or modem, if you have. It is unlikely that will help, but try it for luck.
@Norris.Aufderhar, any luck with this problem? - emmy.Gra commented on April 4th 20 at 00:40

Circuit power supply, the motherboard receives an impulse to activate.
No, this explanation is far-fetched. In reality the feeds have a computer for it as many as 5 pieces (+3.3 volts, +5, +12, -5, -12), and a short on any of these channels leads to protection in the PSU, not allowing at all to turn on the computer. In addition, from the PSU to the motherboard there is a signal called "Power Good" (PG), failing which the OS boot begins. With the closure according to any one of the above channels, this signal is not available.
So here, I think, something more cunning. - tomasa commented on April 4th 20 at 00:42
@tomasa, never tried with a screwdriver to turn a disassembled PC?

Other ways the computer is off: short press the power button, Alt+F4 on the desktop Win+D.

The problem may be the power supply. Try the other one.
