AFter starting or a restart, the following happens.
Windows shows a welcome screen.
It looks like a normal startup.
The screen goes black.
There is no activity on the Hard Drive Light.
For two minutes the screen is black.
Then the screen comes back, and the startup proceeds normally.
I have run Malwarebytes and removed anything found.
I uninstalled unnecessary programs.
I ran Performance Toolkit and tested and repaired the registry.
AVG Internet Security is Installed.
AVG PC Tuneup has an exclaimation point on the taskbar.
When I click on it, the menu offers me the chance to turn it on, which I don't.
The computer has been coming on. The wait is disturbing.
