Good day.
One of the users' computer turns on intermittently.
We press the Power button, the BIOS is loaded and everything is silent. The computer goes into standby mode.
The screen light is blinking and the computer itself is loading something there ... it takes about 3 minutes and it starts to load the system
, turn it off and then turn on the computer, it starts immediately without any hitches
and it may be that it starts right away, maybe not immediately, maybe not start at all you have to grind it to get it going.
thoughts were on the video card. but it disappeared because. after a while, the computer still turns on.
maybe a bad op? in a couple of hours I'll take it for diagnostics, but for now, throw in options for what it could be if anyone has come across such a situation.
Thank you

If you want to get practical advice on the issue, then it’s worth laying out the PC config, which PSU, motherboard, percent, memory, HDD, etc.
If, in fact, I would start with a 99% probability PSU.

1) PSU
2) RAM
3) motherboard is possible, but unlikely

Look at the Windows logs. There may be a disk check, and at that moment the default display switches. Obviously, Windows is doing something at this moment, putting some updates, updating something.

in general, guys, it was a defective vidyukha.
At first, I pulled out all the devices, leaving only a 220v wire. if you do not cut down the PSU, then everything turns on properly, but if you turn it off from the network, then 50 \ 50. then it does not work. then replaced bp. the story is the same, replaced the RAM - it did not help (changed the slot), replaced the hard drive with a new Windows, the problem remained, put everything old back but changed the video. the problem was eliminated. I put the video on another computer and he fell ill with the same thing. And the computers are new.
