Question Strange power outage

[Vollkornbrot]

Hi,

recently I havea strange problem occuring for the second time today.
When it happens I can hear the fans of my Pc switch off for a split second and the screen freezes. Immediately after that the PC fans are starting again (Sounds like when I turn on the PC).
After 10 seconds it unfreezes and I can use my PC again, no need to reboot.
I am a bit clueless what is happening here. The Screens and the light in my room always stay on when this happens, so no power outage in my room/house.
Can this be PSU related?
Any tips are appreciated.
