30 seconds black screen before welcome in windows 7?

Question

Windows

Laptop is 4 years old. The hard drive was covered, installed a new one. Installed Windows, restarted quickly. Then I installed firewood and basic applications such as a cleaner, a player. And after that, when loading before the greeting, it started to hang on a black screen for 20 - 30 seconds. Did a clean boot, no effect. What could be the problem? This is not the first time this has happened on different laptops.

Answer 1

Then I installed firewood and basic applications such as a cleaner, a player. And after that, when loading before the greeting, it started to hang on a black screen for 20 - 30 seconds.

Well, of course, that's the reason.
Where did you put the firewood from? Did you download from the official website of the laptop manufacturer? - in this case, there should be no problems.
But if the firewood is downloaded from any other place - this is normal, as it should be.
With applications, the situation is the same, by installing a couple of players, you can quietly put a bunch of malicious software like ccleaner, a couple of miners, and a dozen trojans on the system.

Answer 2

basic cleaner type applications

The basic system of self-destruction - well done, always do it, we have more work to do!

Answer 3

Cleaner is basically a useless program.
See Windows log. Computer Management - Event Viewer - Windows Logs
As an option to put 10-ku, she does not ask for firewood either.

Answer 4

Look at what you (in the system) have installed in this window;
Path: Control Panel/System/Advanced Options in System Properties under Startup and Recovery

Answer 5

I just launched it, the desktop appeared in 10 seconds, I didn’t even have time to blink. I thought everything was decided by itself, but I need to check, restarted and again this black screen
