Hello,i have built a new computer for no more than 2 months now its pretty high end, ryzen 7 3700x rtx 2070 super etc... so sometimes when i boot my pc windows has a blank black screen with the loading circle and takes about 10-15 seconds to leave from that screen and actually take me to the login screen,any idea why? should i worry? or is it completly normal.. btw this happens sometimes, not every boot..
