Very slow boot times after upgrade.

[Jaridan]

OK so did an upgrade today with parts as follows
I7 9700k
Asus Rog Strix z390-f Motherboard
Samsung 970 evo plus V-Nand ssd
Fresh install of windows 10 pro on the samsung.
All drivers updated for components except bios flashing for the Motherboard.
My boot time is averaging three and a half mintues, ive barely added any programs etc.
It just doesnt feel like a normal boot time to me.
What should i be checking?

Last bios time was 131.7 secs
Ive updated to latest bios, and latest samsung driver. It just seems to sit on the Republic of gamers screen for quite a while and then the rog screen reappears and the little spinning circle will appear to show activity.
Not really sure what else to try.
