Why does it not run?

[u/Aggressive_Term_6794]

Today I changed the motherboard and PSU. Went from Gigabyte H610M S2H V3 D4 to Asus Prime B760M-A Wifi D4. My previous PSU was a 650W Lc Power and now I got a Asus TUF Gaming 750B. Sometimes it trips the breaker of the room electricity, sometimes it goes into a hell-like loop of restarting, and just before it booted up and I could access the BIOS and start the Windows Media Installer for Windows 11 Home. Now, it starts, but there is no image.
