upon pressing the power button the following happens:

immediately red light at "CPU"
(it lights up for like half a second)
as it turns off a yellow light appears at "DRAM"
(it also lights up for only half a second)
after that there is no light for 3 seconds.
followed by a solid white light at "VGA" for 3 seconds.
then the white light turns off

after the white light turns off, there is the msi mag screen on my display, i suppose that means its booting. the login screen appears and i enter my password.
i reach desktop and use my pc as i normally would until it eventually crashes.

my system:
MB: msi mag H670 tomahawk
BIOS ver: E7D25IMS.H90
BIOS build date: 11/july/2022
CPU: intel i5 13600K
GPU: msi rtx 3090 surpim x
RAM: 2x16 GB corsair DIMM DDR4-3600
PSU: thermaltake 850w

I build this pc about 4 weeks ago and have been using it without any issues so far.
about 4 days ago it shut down without any warning sign like stuttering or freezing.
last night i wiped the M.2 where the system is stored and freshly installed win 10 from the bootable USB drive i used 4 weeks ago.
i now downloaded and installed most recent GPU drivers from nvidia.

i turned my pc off and on again to see if the lightshow remains - it did.
not knowing what to do or where to even start, maybe someone here knows how to fix this.
thanks in advance for reading and any answers you guys might have!
