Hi, SeHa! Have you had a look at this guide: https://www.computerhope.com/issues/ch000689.htm before posting?

Hi OP, Did you solve it and how? If not I would like to add are you using UPS? what's the Watts and VA of it and the wattage of your PSU? It might also be the reason if the UPS doesn't have enough power to supply.

Which PSU did you currently using?

Have you tried your computer using any other PSU? Seems like a Power Supply issue
