Hi, maybe overheating problem .. so remove the dust and see. Look too on your cables.
Or try Restore point.

Is there possibility that I got infected with trojan?

There is as good a chance as anything that you have a rootkit with a keylogger. Keyloggers, in a way that they access the keyboard controller chip, can trip the reset pin on the CPU which causes your computer to restart. The keyboard controller chip, that keyloggers manipulate, has a direct line to the reset pin on the CPU. Usually you can tell when your reset pin is being affected by noticing that your power switch on your PC will not work when you push it. Reset pins replaced manual power switches years ago, with the exception being the override switch on the power supply, which is located on the back of your PC towards the top.

If it is simply starting up on its own (not rebooting on its own) I would guess that unless you have a "boot from LAN" capability enabled, you are getting a power surge from a faulty power supply.

It could also be that you don't have all cables plugged in when the computer turns on.

Could you elaborate.

What sort of hardware do you have ie. laptop or desktop? Do you work in a clean environment? How old is your hardware?
Any recent software installations? What security software you have running? Do you keep your OS updated? etc.

That post is a bit confusing. Could you add more?

As Earth says, we need the OS, the config, how old, security software. We cannot work on simply, it won't work.

If you cannot see a screen for about matter of seconds then something a problem in the cable that connects through monitor thus it could start automatically with repetition time.

Try to recall what are your last task on your computer.

Can it be the BIOS settings? Because my father's PC has the setting to turn on the computer automatically at a specified time.

thanks for all information.
Problem solved.
It's not trojan.
Just there's too much dust there.
I clean it, and my computer is ok now.

Glad you found the problem and it was solved. Well its regularly to clean your computer cause dust may clogged through fans thus it could not work well and may overheat easily.
