I have a new problem with my TR3AP.

When I turn the computer on i get the windows logo as normal but then the screen is black for about 5 minutes before the blue windows screen and regular desktop window show up.  Then everything works like normal after that.

I have run all the appropriate virus/adware stuff and have always had my computer protected with PCcillin. 

This just started a few days ago.  What could this be?  I dont want it to get worse or lead to something else?
