Hanging start up

I have a issue with windows 10 taking 30+ seconds to load up. It gets stuck on welcome screen and i never used to have this issue before. Here is my logs. It used to take 2-5 sec tops.

Bootlog shows multiple times
BOOTLOG_NOT_LOADED \SystemRoot\System32\drivers\dxgkrnl.sys


my cbs log shows
