every time I reboot my pc it stays on a gray/black screen with the mouse moving after around 5 minutes it loads my wallpaper and I can use my pc

things I try:

1.- running new task as manager of explorer.exe = nothing

2.- opening file location of a program running = open explorer but still cant run anything takes 5 min

3.-shortcut to refresh gpu drivers = nothing

4.-runing devmgmt.msc as a new task with admin privileges = nothing

I can let the computer alone for 5 minutes on lock screen and no problems shows up
