Windows 10: Black screen for minutes?

Hello I have a very annoying issue.
My system is taking forever to get to the lock in screen, I have black screen for a very long time!
My security is: Bitdefender Total Security+Heimdal(Thor)Pro & Voodoo-Shield Pro.
My Maintance Programs: WiseCare 365 Pro+Ccleaner Pro Plus.
It is not something that just now has happened, it is over time(6 Months maybe),but now it has reached a point where I would like to have something done about it.
I have tried to unninstall some programs I did not use very often, and I had to get rid of Malwarebytes, and it has helped a little but not enough, please help me.
My system is Windows 10 Home 1809 with the latest updates, my Notebook from Acer(Aspire E 15)has only 4 GB DDR4 Ram with a Dual-Core Processor A6-9210 with Turbo core Technology up to 2.8 GHz.
Thanks in advance.*Sad
