Windows 7 boots slowly with black screen after "Welcome"
I'm sure this isn't a new problem or new post asking about that. But I still make this post because every solution I tried didn't work.
Symptom: My Windows 7 64bit boots slowly with a long Welcome screen, then a black screen with cursor for about 5 - 10 seconds and the wallpaper with icons appears.
Video: YouTube
System infomation: Asus K55A
Intel 3230 2.60 Ghz, Intel HD 4000
Not many softwares, Office 2010 is the biggest software I installed
Used solutions:
- Remove start-up programs
- Update drivers and windows system, BIOS
- Run cleaning tool for partition C
- Run defragment tool
- Scan virus, malware with Panda and MBAM
To make sure this is a software problem related to system, I install another Windows 7 on the same laptop, different partition. It has many programs (Photoshop, VirtualBox) taking more space than the first Windows 7 . This Windows boots much faster without disabling startup programs and services. Also It hasn't been updated regularly, even drivers. This windows just has drivers from 2014.
It seems silly, but I have to say that can be explained. To check what happens in booting these two windows, I use boot log.
Bootlog in my first Windows 7 (Slow boot), 461 kb txt file, in the seconds Windows (Fast boot), 18.3 kb
In bootlog of the slow booting OS, many lines say "Did not load driver....", in fast-booting os, just a little
So now I think the root cause is drivers which are loaded in booting proccess. And notice that, I have re-installed, updated the drivers on slow-booting Windows many times, but in fast-booting one, I just installed one time the old version. So maybe many drivers files are exccess or causing something wrong or anything i dont know. But now I think it's definitely because many "did not load driver...."
Boot log on slow booting OS & Boot log on fast booting OS are attached.
Drivers list on slow booting OS:

So what can I do if I dont want to do a clean installation Windows 7?
I'm a technical user, so you can answer with advanced techniques. I just want to do anything if possible to optimize OS without re-installing it. Thanks for your comments!
