Multiple BSOD and sometimes will not power on :(

I have started getting many BSOD all with varying codes, some after a bit, some instantly on or during restart. But on top of that, sometimes I can't power the PC on, the power button (case or MB) does nothing, I have to power off the PSU a bit then it will work.

After the PSU is turned off for 10-15 minutes, upon restart the BIOS is reset too. MB is only 2 years old (Z790).

Any ideas here please? I have made no changes to my PC. I do have a 13900k so could that be failing? Thanks.
