[sew333]

Hi. I have 12900K stock

32 GB 2x16 GB DDR4 3600mhz

Palit Gamerock Pro OC rtx 4090

1300W Seasonic Platinum Prime

Windows 11 2H22. Updated new nvidia drivers.

I unplugged 3090 ti. And plugged Rtx 4090. And on first boot was black screen ( no signal ) on monitor, and motherboard was lightning in red. I waited 4 minutes then i heard windows 11 boot ring sound. And display appear. And its fine now. Why that happehed on first time? Just black screen no signal and red ligt in motherboard ( like before windows ). Now its fine. Should i worry?

Tested 3dmark and its fine.
