Question PC sometimes freezes

[PieWantte]

I have a bizarre problem with a PC I put together.
The pc freezes/crashes sometimes, the bizarre thing is that this usually happens in the first half hour after booting up.
If I reboot after the crash/freeze I have no problem the entire evening.

• The image just stays on the screen but no longer responds.
  If I unplug the display cable once and plug it back in I get a black screen.
• Keyboard and mouse dont respond anymore.
• I don't get a BSOD
• ALT-CTRL-DEL does nothing
• I have experienced this twice this week when watching a youtube video, so there was no heavy load on the system at the time of the freeze.

Specs:

• CPU: AMD Ryzen 9 7900X
• Motherboard: Gigabyte X670 GAMING X AX
• Bios: F6a
• GPU: NVIDIA GeForce RTX 4070 Ti | Geforce Game ready driver: 531.68
• Memory: G.Skill F5-6000J3238F16G
• PSU: Corsair RM850x
• OS: Windows 11 win 22H2

Any help is appreciated

Is Event Viewer or Reliability History showing anything?
